Answer 1

The correct option is A A food chain is a series of organisms feeding on one another, a food web consists of a number of interlinked food chains.

• A food chain is a linear path in which an organism gets food, it starts with plants and ends with animals. A network of many food chains is called a food web.
• A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains.
• Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

Thus, the correct answer is option A.
