Question

Stability of ecosystem depends upon
(a) primary productivity
(b) interchange between producers and
consumers
(c) number of producers
(d) number of consumers

Answer 1

Stability of ecosystem depends upon interchange between producers and consumers.

• Option (b) is correct.
• The network of food chains, a food web interconnected at trophic levels increase the stability of an ecosystem ( a self sustaining and a self regulatory unit) by providing high interactivity between producers and consumers, in turn making ecosystem independent of outside factors for its stability.

Answer 2

The stability of ecosystem depends upon  interchange between producers and consumers.

Option (B) is correct.

Explanation:

• Stability of ecosystem depends upon interchange between producers and consumers.
• Producers and consumers occupy different trophic levels of a food chain.
• The ecosystem becomes more independent and sustainable when the interaction between producers and consumers is extraordinary as compared to outside factors for its stability.

Thus, the stability of ecosystem depends upon  interchange between producers and consumers.
