What is a Food Chain?

Food chain can be defined as the passing of food along with energy from one organism to other by the relationship of eating and being eaten.

Characteristics:

1. Functional units of ecosystem.

2.They includes trophic levels.

3. Food and feeding habitats are pre-determined.

4. Acts as a base for food web.

Types of Food Chain

A. Grazing Food Chain:

It generally starts from autotrophs, goes through herbivores and usually ends in carnivore. It's comparable larger yet limited food chain.

It's of two types:

1. Predator food chain: Includes plants and consumers.

Grass -> Grasshopper -> Lizards -> snakes -> Hawks

Phytoplankton-> zooplankton -> small fish -> large fish

2. Parasitic Food chain: one trophic level exploits other trophic level by parasitism.

Bacteria -> Ascaris -> Humans

B. Detritus Food chain:

This includes dead and live animals with organic matter. It ends with inorganic compounds. It contains less number of trophic level.

Dead organic matter -> Fungi -> Bacteria -> Humus

**Sometime both detritus and grazing food chain are interlinked forming a Y structure hence called as Y food chain.
