A
Increase in the population of coral reefs
B
Decrease in the population of plankton

Decrease in the population of algae
D
Increase in the population of smaller fish species
Verified step by step guidance

Understand the role of sharks in the ocean ecosystem: Sharks are apex predators, meaning they are at the top of the food chain. They help maintain the balance of marine life by preying on smaller fish and other marine organisms.
Consider the impact of removing sharks: Without sharks, the population of their prey, such as smaller fish species, can increase because there are fewer predators to keep their numbers in check.
Analyze the food chain dynamics: With an increase in smaller fish species, these fish may consume more plankton and algae, potentially leading to a decrease in these populations.
Evaluate the indirect effects on coral reefs: Coral reefs may not directly benefit from the removal of sharks, as the increase in smaller fish species could lead to overgrazing on the reefs, potentially harming them.
Conclude the likely consequence: The removal of sharks from the ecosystem is most likely to result in an increase in the population of smaller fish species due to the lack of predation pressure.
