Is secondary productivity storage of energy or the conversion of energy to organic products?

Question

Sir/Madam, 

I have read that Sec. productivity was production of organic matter.

So where does storage of energy fit into sec. productivity?

Hope that you will be able to help me.

Answer 1

1. Secondary productivity is the rate of storage of energy at consumer’s level - herbivores, carnivores and decomposers.
2. Consumers tend to utilize the already produced food materials in their respiration process and also convert the food matter to different tissues.
3. The consumers, either directly or indirectly use the food material from the producers and convert it into different forms.
