b. coral.
c. plankton.
d. kelp.
The correct answer is option C, Plankton
Reason -
In open ocean food web, the organism that lies at the bottom is planktons. Photo plankton consists of chlorophyll and is able to produce food of its own. The zoo planktons then feed on the photo planktons. Corals also survive by eating planktons. Small fishes survive by eating zooplanktons. Larges fishes then feed on smaller fishes. Thus, plankton is at the base of a complex aquatic food web.

Answer: Fatty acids are fats that have acidic carboxyl groups on them. Something like CH3-(CH2)n-COOH Unsaturated fatty acids have double bonds between 1 or more of the carbons in the chain. They are unsaturated with hydrogen, but can be hydrogenated chemically. Fatty acids have many roles, but a very common one is to form the lipids in membranes. In that case two fatty acids are usually joined to phosphate plus some others.
