Question

How do pyramids of net production and pyramids of biomass differ? a. Unlike pyramids of biomass, pyramids of net production are based on measurements per unit time. b. Pyramids of net production include fewer trophic levels than pyramids of biomass. c.Unlike pyramids of net production, the shape of a pyramid of biomass varies with the size of the organisms in the ecosystem.

Answer 1

Answer: c.Unlike pyramids of net production, the shape of a pyramid of biomass varies with the size of the organisms in the ecosystem.

Explanation:

The pyramid of net production defines how energy is added to the bodies of the living organisms in the form of biomass. The pyramid of biomass is the amount of matter that is stored in each organism of the ecosystem. Productivity can take units of either biomass or energy.

The pyramid of net production defines how energy is utilized in metabolism and maintenance in organisms. But in the case of the pyramid of biomass the distribution of biomass varies with the size and weight of the organisms.
