Secondary productivity is rate of formation of new organic matter by consumer.

#16. Which one of the following processes during decomposition is correctly described?

#17. Which one of the following is not a functional unit of an ecosystem?

PAR is less than 50% of the total incident solar radiation.

#28. The breakdown of detritus into smaller particles by earthworm is a process called

#29. The biomass available for consumption by the herbivores and the decomposers is called

The biomass available for consumption by the herbivores and the decomposers is called Net Primary
