Question

Why do naturalists suggest that we plant more trees? Plants use CO2 but do not release any, thus maintaining a balance of CO2 in the atomsphere. Plants release CO2 through respiration and use it for photosynthesis, thus decreasing the amount of CO2 and maintaining its balance in the atmosphere. Plants do not use any CO2, thus maintaining low levels of CO2 and balancing its level in the atmosphere.

Answer 1

Answer: Plants release CO2 through respiration and use it for photosynthesis, thus decreasing the amount of CO2 and maintaining its balance in the atmosphere.

Explanation: respiration process in plants takes place usuallly at night and it's rate is lower than the photosynthesis, that is why plants keep balance and use the CO2 liberated by them and the animals

Answer 2

Naturalists suggest planting more trees because plants release CO2 through respiration and use it for photosynthesis, thus decreasing the amount of CO2 and maintaining its balance in the atmosphere. So option 2.
