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

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

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.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
