Question

1. Why doesn't the level of oxygen in the atmosphere decrease?

2. why doesn't the level of carbon dioxide in the atmosphere increases?

3. Which process in plants regulate the level of oxygen and carbon dioxide in the atmosphere?

please give me different correct answer of the following questions ​

Answer 1

Answer:

1. Yet, the percentage of oxygen in the atmosphere is constant for many years and does not decrease because the green plants which are capable of photosynthesis take up CO2 from the atmosphere and produce O2 in return. It is this process which keeps the oxygen levels fairly constant.
2. The level of carbon dioxide does not rise in the atmosphere because the plants utilise the carbon dioxide for the process of photosynthesis.
3. photosynthesis
4. The process for regulation of oxygen and carbon dioxide is known as photosynthesis. Plants use light energy to use carbon dioxide as food. And in this process release oxygen.

Answer 2

Answer:

The process for regulation of oxygen and carbon dioxide is known as photosynthesis. Plants use light energy to use carbon dioxide as food. And in this process release oxygen.

answer 1: Yet, the percentage of oxygen in the atmosphere is constant for many years and does not decrease because the green plants which are capable of photosynthesis take up CO2 from the atmosphere and produce O2 in return. It is this process which keeps the oxygen levels fairly constant.

answer 2: The level of carbon dioxide does not rise in the atmosphere because the plants utilise the carbon dioxide for the process of photosynthesis
