Biology

Animals obtain energy by consuming food (which contains glucose and other nutrients), and then breaking down glucose through cellular respiration. In this process, glucose is converted into ATP (adenosine triphosphate), the energy currency of the cell, which is used for various cellular activities like growth, repair, and movement.

For A: Animals do not perform photosynthesis. Photosynthesis is a process used by plants, algae, and some bacteria to convert sunlight into chemical energy (glucose). Animals are heterotrophs,...
