c) In dense rainforest, plants that grow close to the forest floor tend to have lower rates of photosynthesis than the very tall trees. Suggest why this might be.

This is because the leaves of the trees above are so dense that they block any sunlight from reaching the forest floor. As a result, it is dark and most plants do not receive enough light to perform photosynthesis, which is how plants make food out of water, carbon dioxide and sunlight.

Please mark me the brainliest!?!
