Question

If there were 2,000 units of biomass among the primary producers of a food chain, how much biomass would be expected among the tertiary consumers in that same food chain? 200 units 2 units 20 units 100 units 1,000 units

Answer 1

Answer:

2 unit

Explanation:

According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.

Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.

that is 2000→200→20→2

note: only 10% of the total biomass is received by the next trophic level.

therefore tertiary consumers will receive 2 units of biomass.
