Question

Sharks feed on a wide variety of prey and have low mortality rates. It is important that an

ecosystem containing sharks contain a high degree of biodiversity. If an ecosystem
containing sharks does not contain a high degree of biodiversity, the sharks will consume
A the immature members of key species, and the ecosystem will no longer be stable.
B many members of a key species, and the ecosystem will no longer be stable.
C the adult members of key species, and the ecosystem will remain stable.
D a few members of a key species, and the ecosystem will remain stable.

Answer 1

B. Many members of a key species, and the ecosystem will no longer be stable.

Step-by-step explanation:

An ecosystem that contains a high degree of biodiversity will have numerous organisms of different species. According to the question, sharks are stated to feed on a wide variety of prey. This means that sharks can feed on any other species of organisms at lower trophic levels.

In a situation whereby an ecosystem contains a low degree of biodiversity i.e. low variety of species, the sharks will have to consume a large numbers of a key species, which will cause the ecosystem to lose stability.
