Energy Flow + Biomass

Question 1

What is biomass?

Answer 1

Biomass is the total mass of living organisms, or organic matter, in a given area or ecosystem, derived from plants, animals, and other living things.

Question 2

What is biodiversity?

Answer 2

Biodiversity is the number and population of different species in an ecosystem.

Question 3

How does energy flow in a food chain?

Answer 3

Energy flows unidirectionally from producers to consumers as they are eaten, with energy being lost as heat at each level. The sun is the original source of energy in a food chain.

Question 4

What is the 10% rule in energy transfer?

Answer 4

When energy is transferred from one trophic level to the next, only about 10% of the energy is passed on; the rest is lost as heat or used for metabolic processes.

Question 5

How can you compare pyramids of biomass and energy?

Answer 5

You can construct and compare pyramids of biomass and energy to interpret how they depict matter and energy transfer.
