Answer:
O C. The population's growth rate is increasing exponentially
Answer:
Plants perform photosynthesis and cellular respiration.
Explanation:
- Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
- Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
- Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
- Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.
