Question

Describe how changes in light, temperature, water, and carbon dioxide affect the rate of photosynthesis.

Answer 1

Photosynthesis is affected by... because
Light, because higher the light intensity, the higher the rate of photosynthesis.
The same applies to carbon dioxide concentration an and water.
When the temperature exceeds the leafs' limit, the stomata close themselves due to too much water loss in the form of water vapour.

Answer 2

Well the whole process depends on these factors or at least some of them. WIthout them the whole system would collapse. Like in machines they all have systems that rely on each other. Now if one part broke down the whole thing is possible to collapse if the part isnt fixed or replaced.
