NEET BIOLOGY

Detailed explanation-1: -Food webs, simply put, describe all of the trophic relationships and energy flow between and among the component species of a community or ecosystem. A food chain depicts a single pathway up the food web.

Detailed explanation-2: -Food webs describe the relationships-links or connections-among species in an ecosystem, but the relationships vary in their importance to energy flow and dynamics of species populations.

Detailed explanation-3: -Biology, Ecology A food web is a detailed description of the species within a community and their relationships with each other; it shows how energy is transferred up food chains that are interlinked with other food chains.

Detailed explanation-4: -Food chains and food webs model feeding relationships in ecosystems. They show how energy and materials are transferred between trophic level when consumers eat producers or other organisms. A food web is a diagram of feeding relationships that includes multiple intersecting food chains.

Detailed explanation-5: -Consumers may be identified by their position in a chain: first order (primary) consumers eat producers; second order (secondary) consumers eat primary consumers; third order (tertiary) consumers eat secondary, and so on along a chain. Consumers high in a food chain do not necessarily eat all species lower down.
