Answer 2

"Food chains refer to the process of energy transfer from producers to consumers through various levels. It is usually classified into two types:

""Grazing food chain""

""Detritus food chain""

Grazing Food Chain:

Grazing food chain involves transfer of energy from the producers to the herbivores to the carnivores. These ecosystems are ""directly dependent"" on solar radiation for the initial energy input.

Detritus Food Chain:

Detritus food chains comprises the ""breakdown"" of dead organic matter by microorganisms and to those species which feed on this broken down matter (detritus) and its predators. These chains are dependent on how much organic matter is available in the ecosystem.
