Select all that apply.

Select all that apply.

Energy is transferred from decomposers to plants to herbivores to carnivores.

The total biomass of the top trophic level is greatest because the top consumers are large.

About 1% of net primary production is available to secondary consumers.

Answer 1

Ans- First statment is wrong because energy transfer in food chain form producer to consumers ,not form decomposer to plant and other trophic level.....

Second statment is wrong because top trophic level have greatest biomass because their are large no. of primary producer but in this statement given consumer so this statement is wrong.

Third statement is correct because according to 10% rule primary producer produce 100% energy and they transfer only 10% to primary consumer , primary consumer transfer 10% energy of primary producer as 1% energy to secondary consumers. So net 1%energy of of net primary production by producer for secondary consumers.
