Answer 1

When primary producers expend energy to build new tissue, this is net primary productivity and the amount of energy available to consumers.

What is primary productivity?

• Primary productivity is the rate at which energy is transformed into organic materials by chemosynthetic producers (chemoautotrophs), who receive chemical energy through oxidation, and photosynthetic producers (photoautotrophs), which obtain energy and nutrients by utilizing sunshine.
• Photoautotrophs are the primary producers of almost all of Earth's primary productivity.

• Gross primary production (GPP) is the sum of all biological productivity in a territory or ecosystem.
• The net primary productivity, which is available to consumers, is what is left after producers (or autotrophs) in a food chain have used up a specific quantity of organic material to support their existence (or heterotrophs, which are made up of herbivores and carnivores in each environment).
