Which statement is TRUE regarding photosynthesis and cellular respiration? [B.2G]Select one:a.These processes recycle matter and transform energy through the ecosystem.b.Matter is used once and is no longer available.c.They are the same process but one occurs in a plant cell while the other occurs in an animal cell.d.Both processes require extra amounts of oxygen to occur.

The correct answer is:

a. These processes recycle matter and transform energy through the ecosystem.

Explanation:

Photosynthesis and cellular respiration are two fundamental biological processes that recycle matter and transform energy in an ecosystem.

Photosynthesis is a process used by plants and other organisms to convert light energy, usually from the Sun, into chemical energy that can be later released to fuel the organisms' activities. This process consumes carbon dioxide and water, produces glucose, and releases oxygen as a byproduct.

On the other hand, cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break down large molecules into smaller ones, releasing energy in the process. This process consumes oxygen and glucose and produces carbon dioxide and water as byproducts.

Therefore, these two processes are complementary. The oxygen produced during photosynthesis is used in cellular respiration, while the carbon dioxide produced in cellular respiration is used in photosynthesis. This way, they recycle matter (carbon dioxide and oxygen) and transform energy (light energy to chemical energy and vice versa) through the ecosystem.
