What is an autotroph and what is a heterotroph
Usimov [2.4K]

Autographs are organisms that make their own food/energy. The only example I can think of (and the only one I think exists) is plants. They make glucose from the sun and other stuff

Heterotrophs are organisms that needs to get its energy from other sources. You and me are heterotrophs (well unless you are a plant lol). We have to eat food to get energy to survive.

Hope this helped!!!

The row of energy in a grassland ecosystem is shown
bixtya [17]

The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.

<h3>Trophic Level</h3>

The higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.

More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.

In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.
