How is Secondary production defined in the context of an ecosystem?

AA) The total amount of solar energy converted into chemical energy by green plants.

BB) The accumulation of organic matter by plants through photosynthesis.

CC) The biomass accumulated by heterotroph organisms feeding on autotrophs.

DD) The energy utilized by plants for maintenance and respiration.

Answer:

C. C) The biomass accumulated by heterotroph organisms feeding on autotrophs.

Read Explanation:

  • In an ecosystem, autotrophs, which include green plants, algae and certain bacteria, synthesize organic food by the process of photosynthesis or chemosynthesis.

  • In the process of photosynthesis, plants take Carbon dioxide from atmosphere water from environment and radiant energy from the sun and produce food in the form of carbohydrate.

  • The accumulation of organic matter by plants is called Primary production

  • Heterotroph organisms feed on autotrophs and accumulate biomass in their body, that is termed as - Secondary production
