Question

how does CO2 affect photosynthesis​

Answer 1

Answer:

For land plants, water availability can function as a limiting factor in photosynthesis and plant growth. If the level of carbon dioxide in the atmosphere increases, more carbon dioxide could enter through a smaller opening of the stomata, so more photosynthesis could occur with a given supply of water.

Answer 2

For land plants water availability can function as a limiting factor in photosynthesis and plant growth.

If the level of carbondioxide in the atmosphere increases, more carbondioxide could enter through a smaller opening of the stomata, so more photosynthesis could occur with a given supply of water.
