Question

What type of model would be most useful when trying to determine the flow of energy in a marine ecosystem?

A model that connects the higher trophic levels with the ones below them
A model that determines the overall population of each type of organism
A model that predicts how different organisms will behave around each other
A model that shows all of the habitats that exist in the ecosystem

Answer 1

a model that determines the overall population of each organism

Answer 2

The correct answer is "A model that connects the higher trophic levels with the ones below them".

Step-by-step explanation:

In a food chain, a trophic level refers to the position at which an organism belongs respect to the start of the chain. Trophic level 1 belongs to primary producers as plants, trophic level 2 belongs to primary consumers such as herbivores, trophic level 3 belongs to secondary consumers as carnivores. A model that connects the higher trophic levels with the ones below them, would allow to establish the flow of energy in a marine ecosystem, because a food chain not only determines how organisms eat each other, but how the energy flows within an ecosystem.
