What is food chain explain and some examples?
Scalar energy is utilized by green plants or producers. From producers this energy.
transferred to the primary consumers (or herbivores), which directly feed on the plants. From herbivores, the energy is transferred to the next trophic level of secondary consumers (primary carnivores). The energy from secondary consumers is finally transferred to the top carnivores or tertiary consumers.
Therefore, all biotic components at different trophic levels from producers to consumers are linked together for their nutritive needs.
Impact of changes to trophic pyramids
This chain of organism (at different trophic levels), in which organisms are linked together for their food requirement, is called food chan. Food cham can better be expressed as ‘a sequence of eaters, being eaten.
A food chain in an ecosystem represents the flow of energy and matter. It can be shown as below- Producers Primary Consumer > Secondary consumer tertiary > consumer Food chains in different types of ecosystems is basically the same but differ in Composition because the nature of producers and consumers is different.
