Food web is constituted by
-
Various interlinked food chains in a community
-
Relationship between animals and plants
-
Relationship between organisms and their environment
-
Relationship between animals, plants and microbes
A food chain can have trophic levels
-
Three or four

Food chain in an ecosystem is defined as the passage of food from one trophic level to the next higher trophic level. The transfer of food from one trophic level to the next level results in the passage of energy through these trophic levels. A food chain can have 3 or 4 trophic levels. Plants are producers which are present in first trophic level. Primary consumers are second trophic levels which eat plants. They are herbivores. Secondary consumer are present make third trophic level. They eat primary consumers and are carnivores. Tertiary or top consumer make fourth trophic level. They are carnivores
Food levels of an ecosystem are known as
-
Producer levels
-
Herbivore levels
-
Consumer levels
-
Trophic levels
A food chain is series of plants/animals which are interrelated in the form of organism being eaten as food by the other. A food chain consists of producers abd consumers. In the given food chain, plants are producers. They are present in the first trophic level. It is also called as T$ _1$ trophic level. The animals eating plants are called as primary consumers. They are herbivores and occupy the second trophic level in an ecosystem. It is also called as T$ _2$ trophic level. Animals eating primary consumers are called as secondary consumers. They occupy the third trophic level in an ecosystem. It is also called as T$ _3$ trophic level.
In general, food webs consist of producers, consumers, and decomposers.

-
Flow of energy - Always unidirectional
A. Gross primary productivity (GPP) is a term used to describe the rate at which plants and other photosynthetic organisms produce organic compounds in an ecosystem. Hence 'GPP - Photosynthetic organisms' are related to each other.
