EVERYDAY SCIENCE

Detailed explanation-1: -Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.

Detailed explanation-2: -Producers use energy and inorganic molecules to make food. Consumers take in food by eating producers or other living things. Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment.

Detailed explanation-3: -A food chain is a model that identifies the feeding relationships and the flow of energy in an ecosystem.

Detailed explanation-4: -Decomposers such as bacteria and fungi break down dead or undigested material (faeces) and enable nutrients to be recycled in an ecosystem. Decomposers feed by a process called saprotrophic nutrition, which involves released digestive enzymes onto the dead material and absorbing the digested molecules.

Detailed explanation-5: -A food web is all of the interactions between the species within a community that involve the transfer of energy through consumption. A food web incorporates different food chains within an environment. These types of interactions occur between producer and consumer, and between predator and prey.
