What do you call the rate of formation of new organic matter by consumers?

The correct answer is Secondary productivity.

Key Points

• Primary productivity is the pace at which producers - plants and other photosynthetic organisms - create new organic matter.
• The rate at which consumers are creating new organic matter is known as secondary productivity. Protists, fungi, bacteria, Deer, cows, goats, horses, etc. are a few examples.
• The entire dry biomass of all living things at a certain trophic level is referred to as a standing crop.
• It stands for biomass that is above ground. It could vary during the course of the year.
• There are two forms of primary productivity:
  • Gross primary productivity, which measures the total rate of photosynthesis and the amount of organic matter consumed during respiration and is influenced by chlorophyll content.
  • The difference between gross primary production and ecosystem organisms' respiration is known as net primary production.

Additional Information

•  Tertiary productivity:​
  • ​The quantity of fresh biomass (weight) that carnivores (animals that eat meat) create over a certain amount of time.
• Primary Productivity:
  • ​The process by which organisms produce their own sustenance from inorganic sources is known as primary productivity. Terrestrial plants and microbiological life, such as algae, make up the majority of primary producers.
• Net Productivity:
  • ​The total amount of food or biomass produced by primary producers minus energy losses, which is also the total amount of food stored by producers, is referred to as net primary productivity.
