Question

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

• A. A) The total amount of solar energy converted into chemical energy by green plants.
• B. B) The accumulation of organic matter by plants through photosynthesis.
• C. C) The biomass accumulated by heterotroph organisms feeding on autotrophs.
• D. D) The energy utilized by plants for maintenance and respiration.

Answer 1

Answer:

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

• 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
