In an aquarium, fish eat shrimp, and a shark eats fish. What would happen to the population of shrimp if the shark was removed from the aquarium?
The balance of the ecosystem is dependent on all biotic and abiotic sources. One cannot survive without the other. If a particular population declines, it affects the whole ecosystem.

Which food might a first-level consumer eat?
Usually, in a food chain, producers are eaten by first-level consumers, Those are then consumed by second-level consumers, and so on. This chain continues in this form and at one point, decomposers feed on these consumers and decompose them.

_________ flows through a food web/chain and powers each organism at every trophic level.
The food chain ensures a unidirectional flow of energy through the ecosystem, that is, from one tropic level to another. Also, energy flow decreases with each tropic level.
