- Different types of food webs.
1. Soil food web.
2. Aquatic food web.
3. Food web in forest.
4. Food web in grassland.
- Schematic representation of food web in grassland is given below.
- Food webs are constructed to describe species interactions (direct relationships).
- The fundamental purpose of food webs is to describe the feeding relationship among species in a community. Food webs can be constructed to describe the species interactions. All species in the food webs can be distinguished into basal species (autotrophs, such as grass), intermediate species (herbivores and intermediate level carnivores, such as mouse and snake) or top predators (high level carnivores such as Hawk).
