Which of the following would be considered a limited resource in the lower depths of the ocean? a. water b. sunlight c. prey d. predators

Answer: Option b Sunlight

Explanation:

A limited resource is the one which is available in the least quantity in a given environment.The amount of sunlight is not available uniformly along the depth of the ocean. The uppermost layer of the ocean receives the most sunlight and is called the photic zone, whereas the lower depths of the ocean are called as the aphotic zone as they do not receive any sunlight at all.

Thus, in the lower depths sunlight is considered as the limited resource.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
