Question

Nearly 30 percent of the native flora in the United States is considered to be of conservation concern. Without human intervention, many of these plants may be gone within our lifetime. For the native birds and mammals of the United States to survive, plant life must be conserved. What product of photosynthesis do plants provide to all animals?

A. oxygen
B. carbon dioxide
C. light
D. hydrogen ​

Answer 1

A.) Oxygen

During the process of photosynthesis plants will take in Carbon Dioxide, which is exhaled by humans and animals, and they take that Carbon Dioxide and turn it into Oxygen. They then release the Oxygen into the air, giving fresh air to breathe for animals and humans.

I hope this helps!
