Question

A lobster’s diet includes fish, other crustaceans such as crabs and other lobsters, clams, mussels, sea urchins, and some of the larger, plant-sized algae. Similarly varied diets are common among many species, including our own. What does this suggest about the species shown in food pyramids?

A.
Many probably feed at more than one trophic level.

B.
Many probably feed mostly within their own trophic level.

C.
Those in the top trophic level are the most numerous.

D.
Those in the bottom trophic level have the most predators.

Answer 1

It's A!

Step-by-step explanation:

Option A is the correct answer because it correctly describes the information provided in the statement about the lobster's diet, and it is consistent with the general patterns of feeding seen in many other species.

Why it's (likely) not the other options:

Option B, "Many probably feed mostly within their own trophic level," is not supported by the information given. The statement mentions that a lobster's diet includes a variety of organisms from different trophic levels, so it is not accurate to say that they feed mostly within their own trophic level.

Option C, "Those in the top trophic level are the most numerous," is also not supported by the information given. The statement mentions the different types of organisms that lobsters eat but does not provide any information about the abundance or distribution of these organisms in the ecosystem.

Option D, "Those in the bottom trophic level have the most predators," is not directly relevant to the information provided in the statement about the lobster's diet. While it is true that organisms at the bottom of the food chain are often the most heavily preyed upon, the statement does not provide any information about predator-prey relationships in the ecosystem.

Hope this helps, I'm sorry if it doesn't! If you need more help, you may ask me! :]
