Question

how are the blue whale and adelie penguin alike as consumers?

Explanation:

Both blue whales and Adelie penguins are consumers in the food web. They are heterotrophs, meaning they cannot produce their own food and rely on consuming other organisms (like krill, small fish, etc.) for energy and nutrients. They are also part of the marine ecosystem's consumer levels (e.g., blue whales are often top - level consumers or secondary/tertiary depending on diet, Adelie penguins are consumers that feed on marine organisms like krill and small fish).

Answer:

Both the blue whale and Adelie penguin are heterotrophic consumers (they don't produce their own food) and rely on consuming other organisms (e.g., krill, small marine life) for energy and nutrients, and are part of the marine ecosystem's consumer community.
