Question

Minimum components needed for an ecosystem to survive are

• A. Producers and primary consumers
• B. Producers and primary carnivores
• C. Producers and decomposers
• D. Primary consumers and decomposers

Answer 1

The correct option is C Producers and decomposers

An ecosystem consists of biotic and abiotic components. Biotic or living components include producers, consumers, decomposers. Abiotic components include air, water, temperature. Minimum components needed for an ecosystem to survive are producers and decomposers. The energy enters into an ecosystem through producers. Producers convert solar energy into chemical energy. This chemical energy is then utilized by consumers. Decomposers are the microorganisms which decompose organic matter. They break down waste organic matter from dead animals and plants and recycle the essential minerals back to the environment. Hence, they are essential for recycling of minerals.

Thus, the correct answer is 'Producers and decomposers.'
