Answer: a. what life may have been like before the evolution of photosynthesis
Explanation:
The mid-Cayman rise is an area that has little light coming in but still has life in it.
Plants are able to provide food for themselves and the rest of us by using photosynthesis to make food. Photosynthesis uses sunlight to make this food.
One would think that photosynthesis was around for as long as plants were around but this is not the case. Life on earth had existed long before photosynthesis became a valuable process to plants.
There is therefore curiosity as to how this life fed itself without using photosynthesis and this is why the life in the mid-Cayman is being explored. The way the life makes food there in the absence of light will shed light on how plants made food before photosynthesis.
