All plants and animals depend upon one essential natural chemical process for food. name and define this process

MRCORRECT has answered the question

Explanation:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

The process by which animals make use of food is called respiration. By this process the animals free the energy captured by plants and other photosynthesizing organisms. They use this energy for maintaining their bodies, breathing, digesting, moving, growing, and reproducing.Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.

answer; i believe that the correct answer is (lung);

b) the inside picture would look at a very high temperature in a very low ph
