Explain the concept of food chains and food webs.

• Food chains display the transfer of energy and nutrients in a linear sequence, while food webs depict the intricate network of feeding relationships in an ecosystem.

• Food chains always start with plants as the primary consumers.

• Food chains are only applicable to aquatic ecosystems.

• Food webs are a simplified version of food chains.
