Question

Total energy fixed by an ecosystem is

• A. Primary production
• B. Gross production
• C. Net production
• D. Secondary production

Answer 1

The correct option is B Gross production

In a food chain, energy stored at the producer level is called as primary productivity. Producer level includes plants. Consumer level includes herbivores, carnivores and decomposers. Primary production is the total energy produced by the plant by photosynthesis. Gross production is the total energy fixed by an ecosystem. Net production is the rate of storage of organic matter which is not used by the consumers, Secondary production is the total energy produced at consumer level.

Thus, the correct answer is 'Gross production.'
