While trees are not the largest level in the pyramid of numbers, they are still the base for both the pyramids of biomass and pyramids of energy.

A. True

B. False

TRUE

Explanation:

The ecological pyramid is the graphical representation of the relationship between different organisms of an ecosystem split into various energy levels.

There are various types of ecological pyramids:

1 Pyramid of energy

2 Pyramid of biomass

3 Pyramid of numbers

The pyramid of numbers represents the number of individual organisms at each trophic level without considering the mass or the size of the organisms. Therefore, in terms of the number of the organisms in an ecosystem the trees may not be the largest tough they may be the largest in terms of the mass and the energy they reserve and hence they are at the bottom of the pyramid of biomass and the energy pyramid.

A. True

While trees are not the largest level in the pyramid of numbers, they are still the base for both the pyramids of biomass and pyramids of energy.

Explanation:

To understand this answer we need to explain certain things. First of all, a pyramid of biomass is an instrument used to represent the relationship between biomass and trophic level. Valuing the amount of biomass at each trophic level. Now, even though trees are not the specimens with more population in this trophic levels, they are the base to all of them.
