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.

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

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.

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded

hope this any more questions i am here plz mark brainliest
