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.
Phospholipids have 2 faces or poles: one hydrophobic (the tails which "run away" from water) and one hydrophilic (the heads which "like" water).
This means that when in a double layer in a aqueous environment, the heads will face the water and the tails will face each other.
