Please help I reallly don’t understand this please just explain how photosynthesis and how water chemical mechanical energy works and how movement of matter and energy from plant work pleaseee help Construct a model to show the movement of matter and energy from plants into other organisms. Show how mass and energy are conserved before and after each interaction. For example, the beginning substances before an interaction equal the ending substances, and vice versa.
Answer:
▪Photosynthesis is the process by which green plants transform light energy into chemical energy.During photosynthesis, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen.
▪Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
Photosynthesis is the process by which green plants transform light energy into chemical energy. During photosynthesis, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen.
What is photosynthesis?The term photosynthesis has been defined as the process in which green plants prepare their own food in presence of sunlight and during this process heat energy converts into chemical energy.
Cellular respiration has been known as the set of the metabolic reactions as well as the processes that take place in the cells of the organisms to convert chemical energy from the oxygen molecules or nutrients into the adenosine triphosphate (ATP), and then release waste products.
The energy and matter present at the start of any reaction will be same at the end of it as they can neither be created nor destroyed but can change from one form to another.
Therefore, Photosynthesis is the process by which green plants transform light energy into chemical energy. During photosynthesis, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen.

All the organisms living in and around the streambed, such as ducks, meadow voles, monarch butterflies, and others All the organisms living in and around the streambed, together with the rocks, substrate, water, surrounding air, and other non-living components Non-living components of the streambed and the organisms living outside the streambed Non-living components surrounding the streambed and the organisms living inside the streambed
Answer: All the organisms living in and around the streambed, together with the rocks, substrate, water, surrounding air, and other non-living components
Explanation:
An ecosystem is interaction between living and nonliving things in an area. There are biotic and abiotic factor, abiotic means non living things such as air and biotic means living things such as animals.
All the organisms living in and around the streambed, together with the rocks, substrate, water, air, and other non-living components, make the ecosystem. Thus, option B is correct.
What is an ecosystem?
An ecosystem is where biotic factors like plants, animals, and microorganisms live and interact with the abiotic factors like water, trees, land, soil, rocks, air, etc.
The ecosystem of the flocks of ducks around the streambed will include the ducks, microbes, and other biotic factors along with the streambed, rocks, air, water, etc.

What do you think climate change is? List as many facts in your definition as you can!
Answer:
Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. In the time since the industrial revolution the climate has increasingly been affected by human activities that are causing global warming and climate change. The climate system receives nearly all of its energy from the sun. The climate system also radiates energy to outer space. The balance of incoming and outgoing energy, and the passage of the energy through the climate system, determines Earth's energy budget. When the incoming energy is greater than the outgoing energy, earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and earth experiences cooling.

What is another name for macroevolution? A. speciation B. genetic economy C. globalized evolution D. Mendel's Law
Another name for macroevolution is speciation, which is present in Option A as macroevolution refers to large-scale evolutionary changes, including the origin of new species.
What is speciation?Macroevolution refers to large-scale evolutionary changes that occur over long periods of time, such as the origin of new species, the diversification of major groups of organisms, and the extinction of entire lineages. Speciation is the process by which new species arise from existing ones, and it is one of the primary mechanisms of macroevolution. Allopatric speciation occurs when a population is geographically isolated from the rest of its species and undergoes genetic divergence over time, eventually resulting in the formation of a new species, and sympatric speciation occurs when a new species arises within the same geographic area as its parent species, often as a result of reproductive isolation caused by ecological or behavioral factors.
Hence, another name for macroevolution is speciation, which is present in Option A.

Identify the types of breezes and the areas of high and low pressure that cause them.
Answer:
Explanation:
Breeze are formed from difference in air temperature .
We have the land breeze and sea breeze,
The sea breeze blows from the inward part of the ocean to the land. It takes place during the day, when sun heats up the land it increase the temperature in the ground causing land to heat up resulting in warm air and low pressure but it takes a longer time for ocean body to heat up hence the pressure in the ocean is usually higher, this result in sea breeze.
Land breeze is the breeze that blows from the land to the ocean. At night, land looses the heat cause by increase temperature and becomes cooler but because it takes a longer time for ocean body to get warm heats accumulated are not easily given up hence the pressure on ocean is usually low at night while the pressure of land is higher the difference beings about air breeze from land to the sea.

What is an ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors.
Numerous diverse living things that interact with one another makeup ecosystems. Producers, consumers, and decomposers are the three groups of living things that make up an ecosystem. Each of them contributes significantly to the ecology. The flow of energy is always unidirectional in an ecosystem.

What are two things that chlorophyll does for a plant.
hello,
here is your answer:
**********
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. Chlorophyll gives plants their green color. Chlorophyll’s job in a plant is to absorb sunlight. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide and water into glucose (a type of sugar). Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts. The process of photosynthesis produces oxygen, which is released by the plant into the air.
