GENERAL KNOWLEDGE

Detailed explanation-1: -Energy stored at the consumer level is called as secondary productivity. It is the rate of energy storage at consumer level. Consumer level includes herbivores, carnivores and decomposers. Gross primary productivity is the rate of photosynthesis.

Detailed explanation-2: -They show net primary productivity, which is how much carbon dioxide vegetation takes in during photosynthesis minus how much carbon dioxide the plants release during respiration (metabolizing sugars and starches for energy).

Detailed explanation-3: -Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it’s the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

Detailed explanation-4: -Net primary productivity (NPP) is the rate at which all plants in an ecosystem produce net useful chemical energy. While gross primary productivity (GPP) is the rate at which primary producers save and collect biomass for energy conservation. NPP is the difference between GPP and cellular respiration.

Detailed explanation-5: -Complete answer: Primary productivity is the rate of formation of new organic matter by producers ie. Plants and other photosynthetic organisms. Secondary productivity is the rate of formation of new organic matter by consumers.
