Which trophic level contains more energy: a trophic level of herbivores or a trophic level of carnivores? Why?
Bas_tet [7]
Hello :)

The answer to your question is a trophic level of carnivores


Only a fraction of the energy available at one trophic level is transferred to the next trophic level.

Since carnivores are above herbivores in the trophic levels, herbivores have more energy than carnivores.

Hope this helps and have a great day!

_________ would deal with determining the age structure of a city's residents.
RideAnS [48]

Option D, Demography. I’ll go over why the other three options are wrong.

Ecology studies organisms and how they react to each other, not the age structures of cities!

Anthropology is the study of humans from the past, which doesn’t really have anything to do with the ages of people in a city.

Biology studies life and organisms, but doesn’t specifically cover ages of people in a city.

Demography, on the other hand, is the study of statistics of populations of humans. Obviously, this option is the correct option.
