In a food web nitrogen moves from the air into the soil, into living things , and back into the air. True or false

True

Explanation:

True

Explanation:

Most organisms take in nitrogen form the air or water and use it to carry out their life processes. In the food web, nitrogen moves from the air into the soil, into living things, and back into the air. The air around us is about 78 percent nitrogen gas, but most organisms cannot use this "free nitrogen".

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
