Humans affect the carbon cycle in many ways through the use of fossil fuels, clear cutting of forests, and controlled burns. which of the following processes can counteract these human interactions?
a. photosynthesis
b. respiration
c. decomposition
d. building proteins

The correct answer is A.photosynthesis

In the process of photosynthesis plants use the energy of the sunlight and absorbed CO2 from the atmosphere to create simple sugars. In this process, plants also create oxygen molecules that are released to the athmosphere.

Human activities that involve burning fossil fuels cause a release of a huge amount of CO2 to the atmosphere. Photosynthesis in plants can reverse the effects of this, but only to a certain extent. This is, but all means, not enough to stop the global warning effect that the CO2 build-up in the atmosphere is causing.

The correct answer is -

A.photosynthesis.

Explanation:

Human activities such as burning of fossil fuels (like coal and oil) , clearing of forests can lead to the accumulation of CO2 (carbon dioxide) in the atmosphere, which affects the carbon cycle.

This can lead to many harmful effects like global warming (overall rise in the earth temperature).

These human interactions can be counteracted through photosynthesis.

Photosynthesis is a process of formation of food (glucose) in green plants and algae using CO2 and water in the presence of sunlight.

It releases oxygen in the atmosphere as a byproduct of this process.

The atmospheric CO2 can be reduced through photosynthesis and therefore, it can help counteract the given human activities.

Thus, option A) is the right answer.

c

explanation:

the scientific method.
