Answer 2

Respuesta:

                                              IT DEPENTS

Explicación:

Plants respire all the time, day and night. But photosynthesis only occurs during the day when there is sunlight.

Depending on the amount of sunlight, plants can give out or take in oxygen and carbon dioxide as follows

​1. Dark – Only respiration takes place. Oxygen is consumed while carbon dioxide is released.

2. Dim sunlight – Photosynthesis rate equals respiration rate. A plant consumes all the oxygen photosynthesis generates. It also uses all the carbon dioxide respiration creates. As a result, no gas exchange takes place with the environment.

3. Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen. Extra oxygen is released into the atmosphere.
