OBJECTIVE FORESTRY

Detailed explanation-1: -food web, a complex network of interconnecting and overlapping food chains showing feeding relationships within a community. A food chain shows how matter and energy from food are transferred from one organism to another, whereas a food web illustrates how food chains intertwine in an ecosystem.

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: -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.

Detailed explanation-4: -An organism which feeds on a producer are called primary consumers and will also be herbivores, since producers tend to be mostly green plants. The next organism in the food chain is the secondary consumer which will be eaten by the tertiary consumer.
