How does competition affect an ecosystem? Explain in your own words how competition works in an ecosystem.
(asking again because the only answer i got was not helpful, brainliest ti best one that helps)
Answer:
competition affect an ecosystem because there has to be an equal amount of prey and consumers. That there's more consumers than prey, all the prey will get eaten up in the ecosystem will eventually die off because there's nothing for the consumers to consume anymore.

3. Explain how you can use the classification tree to distinguish heterotrophic bacteria from heterotrophic protists.
Answer:
Heterotrophic protists are not capable of making their own food. In order to live, they have to obtain carbon containing nutrients from the environment or by ingesting other living organisms. This lesson will describe a few of the mechanisms they use for feeding.
What are Protists?
Because they are such a diverse kingdom, it's easier to define protists by describing what they are not rather than describing what they have in common. The biggest shared feature of protists is that they don't belong in any of the other eukaryotic kingdoms. Protists are not plants, animals, or fungi. For example, kelp or seaweed appear to have leaves and roots like plants, but do not have the same specialized tissues.
All organisms need to obtain organic carbon and energy to stay alive. Protists have a variety of ways getting both carbon and energy. Some protists are autotrophic and are able to make organic carbon-containing nutrients like glucose. Other protists are heterotrophic, and can't make their own carbon containing nutrients. Heterotrophic protists have to obtain carbon-containing nutrients by ingesting them -- by 'eating' other organisms or decaying organic matter in the environment.
How Do Heterotrophic Protists 'Eat'?
Heterotrophic protists have many ways to obtain nutrients from the environment. Some have specialized structures designed for obtaining food while others are passive and have to wait on the nutrients to come into contact with their plasma membrane.
Many protists are predatory and have specialized structures designed to capture and aid in bringing nutrients inside their cells. Some have structures that are kind of like mouths, and others fold themselves around and slowly dissolve their prey in order to obtain the carbon necessary to live. Moreover, some protists have 'weapons' that allow them to trap, paralyze, or kill their prey.
Filter Feeding
Protists such as paramecium use cilia to filter feed. Some filter feeders such as the paramecium have trichocyst, which are specialized cilia that the organism projects in order to paralyze or kill prey. Filter feeders use their cilia to create a current that brings prey close their oral groove that connects to the cytopharynx, which is a structure directs the ingested food into the cytostome. The cytostome is similar to a mouth in that it functions as an opening to allow food to enter the cell. Once inside the cytostome, the food will enter a food vacuole that contains enzymes that break down food into smaller components the protists can then use as nutrients. Once the food is digested, the waste is expelled from the cell through the cytopyge, which serves as the anus.
Figure 1: Paramecium uses the cilia surrounding their oral groove to filter food from the environment.
Filter Feeding
Phagocytosis
Phagocytosis is a process where a cell extends its plasma membrane around a large particle to be internalized. Extensions of the plasma membrane are called pseudopodia. Some amoebas use phagocytosis to ingest prey. To accomplish this, they extend and wrap pseudopodia around the organism to be eaten. Think of the process as a fatal hug. Once inside the amoeba, the prey is digested in a food vacuole.
Figure 2: Amoebas embrace their prey until they are taken inside of a food vacuole and digested.
Phagocytosis
The foraminifera are amoebas that have shells. The presence of a shell makes phagocytosis a bit more complicated, so these amoebas extend thin pseudopodia called filopodia, which capture prey. Once the prey is trapped, the amoeba is able to steal nutrients.
Figure 3: Amoebas with shells entangle their prey in filopodia.
Filopodia
Peduncle
Some species of dinoflagellate protists form a peduncle ,which is a tube-shaped structure used to suck nutrients out of prey. Some dinoflagellates even steal mitochondria and chloroplasts from their prey. When dinoflagellates steal chloroplast, they temporarily gain the ability to do photosynthesis in addition to carbon containing nutrients.
Figure 4: Protists like the dinoflagellate dinophysis can steal nutrients, chloroplasts, and mitochondria using a peduncle.
Peduncle
Pallium
A pallium is similar to a peduncle except that instead of being tubular, it is shaped like a veil or net. It is as if the protists wrap their prey in a blanket from which there is no escape. The pallium encompasses the prey and removes the cytoplasm.
Figure 5: Protoperidinium uses a pallium to capture and remove the cytoplasm from its prey.
Pallium
How Can They Eat if They Don't Have Mouths?
A few species of protists do not have specialized structures to catch or ingest nutrients. These protists must absorb nutrients from the environment through their plasma membranes. Many of these organisms are saprophytic and feed on dead organisms. Since most carbon-containing nutrients are too large to fit through the plasma membrane, specialized proteins embedded in the membrane bring the nutrients into the cell.
Explanation:
It provides information about the differences of both bacteria and protists.
The classification tree provides information that bacteria and protists are two different organisms on the basis of their structure of cell and other characteristics. Heterotrophic bacteria are those bacteria which obtain nutrition or feed on other organisms such as Agrobacterium, Pseudomonas, Salmonella, Escherichia, Rhizobium, etc.
Heterotrophic protists are those protists which obtain nutrition by feeding on other compounds such as bacteria, decaying organic matter, and other protists. Examples of heterotrophic protists are amoebas, paramecia, water molds, and slime molds etc.

Explanation:
Plants use carbon to photosynthesize, animals exhale carbon, emitting it into the air, contributing to the carbon cycle.
Answer:
Pretty sure it's D.
Photosynthesis is an important part of the carbon cycle, due to the massive use of carbon during its life. Plants take in carbon and release oxygen to survive and help them live, which lets us survive as well. Respiration is in our bodies, made up of our lungs, which helps with gas exchange. Therefore, another part of the carbon cycle due to the intake and release of carbon and oxygen.

The process of hearing is very complex. Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones into the inner ear. The inner ear is also called the cochlea. Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that sound is.
What energy transformations occur between entering the ear and the brain?
Electrical energy to sound energy to mechanical energy
Sound energy to mechanical energy to electrical energy
Mechanical energy to electrical to sound energy
Sound energy to electrical energy to mechanical energy

Which of the these combinations result in the expression of a recessive trait?
a. two dominant alleles
b. A Y chromosome
c. two recessive alleles
d. a dominant allele and a recessive allele
The combination of two recessive alleles results in the expression of a recessive trait. So the correct option is C.
What is the law of dominance?
The law of dominance was given by Sir Gregor Mendel. The law states that ‘In crossing between homozygous organisms for contrasting characters of a pair, only one character of the pair appears in the first generation.’
This law of dominance was the first law of heredity that was proposed from the findings of Mendel. It studies the characters and explains that all characters present in an individual organism are controlled by separate units called factors. These factors are present in pairs.
These pairs can be homozygous or heterozygous. In the case of heterozygous pairs, only one of the factor present will dominate the other. The dominating character is called the dominant character, and the unexpressed character is the recessive character.
The recessive character is latent, but it is transmitted to the offspring in the same manner as the dominant character is transmitted. The recessive character will only be expressed when the offspring receives both copies of the same allele and this results in a homozygous individual.
Therefore the correct option is C.

Which of the following are pieces of evidence that Wegener used to support his idea? (Check all that apply.)
Question 58 options:
climate zones
glaciers
rocks
biomes
Answer:
glaciers
rocks
Explanation:
Alfred Wegener used the following evidence to support continental drift: ⎫ The fit of the continental margins across ocean basins ⎫ Matching rock sequences and mountain ranges on different continents ⎫ Climate evidence such as glacial deposits in areas that are now close to the Equator
Glaciers following are pieces of evidence that Wegener used to support his idea.
What is glacier?
A glacier is a sizable, enduring mass of crystalline ice, snow, rock, silt, and frequently liquid water that forms on land and slides down a slope due to gravity and its own weight.
The average annual temperature is almost below freezing.
Winter precipitation results in considerable snow accumulations, yet temperatures throughout the rest of the year prevent the snow accumulation from being completely lost.
The snow eventually becomes a significant enough amount after several decades of continuous accumulation for the process of turning snow into glacier ice to start. Size is used to classify glaciers (i.e. ice sheet, ice cap, valley glacier, cirque glacier).
Therefore, Glaciers following are pieces of evidence that Wegener used to support his idea.
