Latika has prepared a food web which is a network of interconnected food chains. Which of the following are involved in a food web?
1. Producers
2. Sunlight
3. Herbivores
4. Secondary consumers
- Only 2 and 3
- Only 1, 2 and 3
- Only 1, 3 and 4
- Only 1 and 3
Answer
Only 1, 3 and 4
Reason — A food web is a network of interconnected food chains and includes different living components of an ecosystem. Producers form the first trophic level. Herbivores are primary consumers that feed on producers. Secondary consumers feed on herbivores. Sunlight is the primary source of energy for producers, but it is not itself a living component of a food web.
