Alternative Title: primary plant succession
Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.
Primary succession
Primary succession
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.

Ecological succession
Pioneer species
Lava-sterilized landscapes, newly formed sand dunes, and rocks either deposited or scoured by retreating glaciers are examples of settings in which primary succession often occurs, because these places either lack soil or their soil cannot sustain life. On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not grow tall but do reproduce quickly. After these plants germinate and grow, they die and decompose, and their remains create pockets of soil in which other plants, as well as fungi, can become established. Over time, such fast-growing vegetation covers more and more of the island, and seeds from other, hardier, taller-growing plants arrive on the wind or are transported by birds that begin to use the island as a stopover during migration.
Surtsey
Surtsey
Surtsey, a volcanic island off the southern coast of Iceland, emerged from the Atlantic Ocean in a fiery eruption in November 1963. Shortly thereafter plants such as sea rocket (Cakile arctica), sand ryegrass (Leymus arenarius), oysterleaf (Mertensia maritima), and seaside sandplant (Honckenya peploides) colonized the island. Much of Surtsey's vegetation is composed of lichens and mosses. However, some higher plants such as the dwarf willow (Salix herbacea) and tea-leaved willow (S. phylicifolia) have grown on the island since the 1990s.
ARCTIC IMAGES/Alamy
These new arrivals shade out sun-loving grasses, shrubs, and other pioneer species, and their cast-off parts decay and add to the soil, altering it by mixing with soil particles left by the decay of earlier plants. More plants and animals arrive (the latter rafting over on flotsam or flying from nearby islands or the mainland), and some become established on the island. The ecosystem changes with each new arrival. Over several decades, the biological community transitions from collections of pioneer and intermediate species to a climax community—that is, a relatively balanced ecological stage whose ecological structure and species composition are far less volatile than those of earlier stages.

2. How is the synthesis of ATP in the electron trans-
port chain of mitochondria similar to the syn-
thesis of ATP in chloroplasts?
Answer:
Explanation:
They’re nearly identical in the actual events of ATP production.
Both take protons that have been ‘pumped’ into a membrane-contained area of the organelle (chloroplast or mitochondrion). These protons flow through the F1/F0 ATP synthase, which does the actual jamming of a phosphate onto ADP to create ATP.
Both pumped those protons by ‘harvesting’ the energy of electrons through passaging those electrons between special protein complexes in a membrane (electron transport chains).
The key differences are in where those energized electrons came from in the first place. In mitochondria, the electrons were ripped from sugar pieces in the Kreb’s/TCA cycle. In photosynthesis, electrons were energized by sunlight (and are then replaced by taking non-energized electrons from water, which is where oxygen is made)

HELP!! I WILL MARK BRANLIEDT!! HERES A PIC ITS ABOUT NATURAL AND SELECTIVE BREEDING:)
Answer:
Natural Selection
- The process happens due to environmental activity
- It takes a relatively long period of time.
- Excessive warmer temperatures in a region have caused rabbits with longer fur to slowly disappear.
Selective Breeding
- Organisms do not choose to thrive but are selected because they are best adapted to the environment.
- A Labradoodle is created by scientists to be hypoallergenic but still look like a Labrador.
- It takes place over a relatively short period of time.
- Humans have a decision in the outcome of the offspring.
- Apples have gotten much larger over the last 30 years due to customer demand
Explanation:
From the above, I have been able to place them in their respective categories.
Natural selection simply has to do with nature. It is a process in nature that leads to the better adaptation of organisms to survive and reproduce in their environment. This type has to do with the natural environment. As nature plays out, it can take longer time and the environment can affect survival rate. Natural selection can lead to speciation.
Selective breeding can also be referred to as artificial selection. This process has to do with the input of man in developing new organisms that possess desirable characteristics and that can adapt to a specific environment. In other words, humans control and decide the outcome of the species that are reproduced. Such breeding process take relatively short time.

Clearly explain the role of mutations in evolution.
Answer:
Mutations are changes in DNA and changes in DNA affect all aspects of an organisms life. The first step to evolution is mutation since it creates new DNA sequences for certain genes. By doing so, is creates new allele. The allele is able to spread through reproduction. All genetic features were initially caused by mutations. Mutation is practically the only way in which a species can have a new variation and so, mutations are the raw material of evolution. Although only hereditary mutations cause evolution, mutations have a large impact on evolution.

Explain how this simulation does and does not represent real life Make a baby lab
Answer:
The simulation represents real life make a baby by showing the probabilities that the child has of inheriting a trait and how the expression of them works. That is to say, the dominant and recessive traits. It does not represent reality in the sense that gene inheritance and expression are not determined by the flip of a coin or the absence of crossing over, which gives gen diversity.
Explanation:
The make a baby lab explains in a simple way how inheritance and dominance of one gen over another works. It shows that there are probabilities to inherit a trait by using coin flipping as an example. Even though the process is more complex, the idea of how dominant genes, recessive genes, and inheritance from both parents work is explained simply with this activity.
The way that this simulation does not represent real life making a baby lab is that; in regards to the dominant and recessive traits. They do not represent true reality in the aspect that gene inheritance and expression are not truly determined by the flip of a coin or the absence of crossing over, that the simulation used to give proof of gene diversity.
Dominant and Recessive GenesThe simulation being referred to in this question is called "Create a body Lab".
This simulation tries to prove the inheritance and dominance of one gene over another one. That is dominant gene over the recessive gene.
This simulation uses a coin flipping technique to make us know that the probabilities of one inherit a trait.
Now, the way that this simulation does not represent real life making a baby lab is that in regards to the dominant and recessive traits. They do not represent true reality in the aspect that gene inheritance and expression are not truly determined by the flip of a coin or the absence of crossing over, that the simulation used to give proof of gene diversity.

Using two spring scales students pull on opposite sides of a dynamic card at rest 5 N of force is pulling left in 5 N force is pulling right describe the motion of the card
Answer:
The card will remain stationary, and will not move.
Explanation:
The card will remain stationary, and will not move because the resultant force acting on the card is equals to zero.
To understand the concept of resultant forces, we can think of a tug of war game. The difference between the forces of the two opposite teams refers to the resultant. It is more like a force imbalance. The team with the higher force wins. If the forces of the teams are equal, the resultant force becomes zero and there is a stalemate.
The same happens in or physical system in which the dynamic card is pulled. Because the two forces pulling the card are equal and opposite, there is a stalemate, and they cancel out each other, thus making the card stationary.
A species of bird ate many types of seeds, each type coming from a different species
of tree. The birds' beaks varied in size, with some individuals having slightly smaller
beaks and others having slightly larger beaks.
slightly smaller beak
slightly larger beak
A few years went by without much rain, and the only species of tree that survived had
large seeds. Many generations later, almost all the birds had the slightly larger beaks.
How is this best explained?
Answer:
I took this in middle school option 3
Explanation:
Answer:
The bird most likely had to adapt so they had to eat whatever they could. Doing so made their beaks larger, the muscle under neath probably started to grow from all the movement trying to eat the large seeds. LOL i really dont know but it seem reasonable i guess.

Discuss how temperature and amount of precipitation can affect the type of plants and animals found in
the rainforest biome.
Answer:
mark as brainliestExplanation:
Temperature and the amount of precipitation, a combination known as climate, affects the type of plants and animals found in the rainforest biome by directly influencing the ecosystem. The high temperatures and rain create a warm, damp environment that insects enjoy living in, which in turn attracts animals that eat insects, and animals that eat those animals. As a result, many kinds of plants, animals, and insects have all evolved to suit the rainforest environment that nurtures life so passionately. This variety of creatures is known as biodiversity, which is what makes rainforest biomes unique. In conclusion, temperature and precipitation caused biodiversity in rain forests, which affected and still affects plants and animals living in the climate.
