Question 10(Multiple Choice Worth 1 points) Which trophic level is most likely to contain the largest population of organisms within an ecosystem? First trophic level Second trophic level Third trophic level Fourth trophic level Fifth trophic level

Answer 1

First trophic level

Step-by-step explanation:

The energy distribution among the trophic levels varies greatly. In general, we can say that the lower the trophic level is, the more energy it has, and the higher the trophic level is, the less energy it has.

This same principle goes for the population size in the trophic levels as well. The lower the trophic level is, the higher the population is, the higher the trophic level, the lower the population is.

These two things are connected. The populations in the lower trophic levels are higher because there is much more energy, while the populations in the higher trophic levels have lower populations because the energy available is much smaller.

The first trophic level has the highest populations by far, and the reason behind it is that the organisms of this trophic level are actually able to produce their own food, thus energy.
