Question

______________ in the food chain forms the food web.

• A. Only plants
• B. Only animals
• C. Only carnivores
• D. Organisms linked

Answer 1

The correct option is D Organisms linked

A food chain is a chronological series of organisms each depending on others for food. A food web is a complex interlinked network of food chains.

The sun is the ultimate source of energy. The energy flows from the producers towards consumers in a food chain.

Autotrophs (like grass ) are the organisms which are able to synthesise their own food. They obtain the energy from the sun and convert it to chemical energy in the form of carbohydrates. Hence, it is a producer.

Energy from the producer is obtained by consumers (primary, secondary and tertiary). Primary consumers are herbivores (rat) whereas secondary (snake) and tertiary (hawk) consumers are generally carnivores called primary and secondary carnivores.
Different organisms link to form the web, not just producers (plants) or consumers (herbivores or carnivores). Hence option d is correct.
