Question

carbon dioxide is a waste product of cellular respiration.
fill in the blanks below.

1. photosynthesis and cellular respiration are complementary processes.

photosynthesis removes carbon dioxide from the atmosphere while returns it.
photosynthesis
cellular respiration

Explanation:

Photosynthesis uses carbon dioxide (\(CO_2\)) from the atmosphere to produce glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)). Cellular respiration breaks down glucose to release energy, with carbon dioxide as a by - product. So, while photosynthesis removes \(CO_2\) from the atmosphere, cellular respiration returns it.

Answer:

Cellular respiration
