Question

unit 3 test.m
predict how it would benefit the environment to have more living plants than animals.
excess carbon in the environment, generated by humans in non - respirative ways, such as combustion, can be removed by plants and converted into glucose.
excess water in the environment, generated by humans in non - respirative ways, such as combustion, can be removed by plants and converted into glucose.
excess carbon in the environment, generated by humans in non - respirative ways, such as combustion, can be removed by animals and converted into water.

Explanation:

To solve this, we analyze photosynthesis: plants use carbon dioxide (from combustion - a non - respiratve human carbon source) in photosynthesis to make glucose ($\ce{6CO_2 + 6H_2O ->[light][chlorophyll] C_6H_{12}O_6 + 6O_2}$).

• The second option is wrong as plants don't use excess water from human non - respiratve ways to make glucose.
• The third option is wrong because animals don't remove excess carbon from combustion to make water; plants use carbon for glucose.
• The first option is correct as it matches the photosynthesis process where plants take excess carbon (as $\ce{CO_2}$) from human non - respiratve sources (like combustion) and convert it to glucose.

Answer:

The first option: "Excess carbon in the environment, generated by humans in non - respirative ways, such as combustion, can be removed by plants and converted into glucose."
