Question

the flow of energy in a grassland ecosystem is shown. based on the diagram, which two populations best represent trophic levels that receive the least amount of the total energy provided to the ecosystem by the grass? crickets and sparrows toads and spiders rabbits and mice hognose snakes and owls clear all

Explanation:

In an ecosystem, energy transfer follows the 10 - 90 rule where only about 10% of energy is passed on to the next trophic level. Higher trophic levels receive less energy. Hog-nose snakes and owls are at higher trophic levels in the food - web compared to the other options. They are either secondary or tertiary consumers and thus receive the least amount of the total energy provided by the grass.

Answer:

Hognose snakes and owls
