Biodiversity and Food Chain

A food chain exists because of bio-diversity. Animals (includes man) sustain life & manage changes through food chain. 4/5th of the atmosphere is Nitrogen. Legumes with the help of microbes in the nodules on their roots convert Nitrogen into plant protein. All Plants make food (carbohydrates) from sunlight and carbon which is the primary producer in the food chain.

Herbivores which eat plants are the Primary consumers. Secondary consumers eat herbivores; tertiary consumers are carnivores that eat carnivores and quaternary consumers like VULTURES feed on live or dead animals.

Then there are detrivores which are organisms that break down body. So, a bear eating berries is primary consumer, secondary when it eats rodent and tertiary when eats salmon. Then there are unique sea weed eating sheep the ‘North Ronaldsay’ in Orkney Islands of Scotland.
