a.) producers break down dead organisms, whereas consumers eat other organisms.
b.) producers eat other organisms, whereas consumers make their own energy. c.) producers eat other organisms, whereas consumers break down dead organisms.
d.) producers make their own organic molecules, whereas consumers have to eat other organisms.

D.) Producers make their own organic molecules, whereas consumers have to eat other organisms.

Explanation:

A food chain is a sequence of transfer of food and energy when one type of organism is eaten by another type of organism. A marine ecosystem typically comprises of aquatic plants and animals.

Among the options given, D.) Producers make their own organic molecules, whereas consumers have to eat other organisms. is the correct option this is because of the fact that producers are able to conduct the process of photosynthesis in order to produce their food in the form of organic molecules such as glucose to obtain energy. But consumers are incapable of producing their food hence, they are dependent on other organisms for obtaining their food like plants or other animals.
