Question

Q50. With reference to the food web, consider the following statements
1. The same food resource is part of more than one chain
2. A food web complexity decreases the chance of survival of the organisms in an Eco-system by Competition.
Select the correct answer using the codes given:

• A. (a) Only 1
• B. (b) Only 2
• C. (c) Both 1 and 2
• D. (d) None of the above

Answer 1

The correct option is A (a) Only 1

A food web illustrates, all possible transfers of energy and nutrients among the organisms in an ecosystem, whereas a food chain traces only one pathway of the food. If any of the intermediate food chain is removed, the succeeding links of the chain will be affected largely. The food web provides more than one alternative for food to most of the organisms in an ecosystem and therefore increases their chance of survival
