A gas produced by animals during respiration that plants use for photosynthesis.
A
Oxygen
B
Carbon Dioxide
C
Photosynthesis
D
Radiation
Explanation: 

Detailed explanation-1: -Answer: Solution: Animals, during respiration, take in oxygen and release carbon dioxide gas. Plants, on the other hand, utilize this carbon dioxide gas in the process of photosynthesis to produce food and release oxygen in the atmosphere.

Detailed explanation-2: -All animals take in oxygen and release carbon dioxide during respiration.

Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
