Grassland Ecosystem is an area where the vegetation is dominated by grasses and other non-woody plants. It possesses various food chains.
A food chain refers to the chronological series of organisms each depending on others for food. These organisms occupy different levels in the food chain and each level is referred to as the trophic level.
Producers occupy the lowest trophic level. They are able to synthesise their own food utilising the energy coming from the sun. These are called autotrophs and examples include grasses and shrubs in a grassland ecosystem.
The herbivores (deer) called as the primary consumers directly feed on the producers and they occupy the second trophic level.
Herbivores are further eaten up by the carnivores which come later in the food chain at third (fox) and fourth (tiger) trophic levels referred to as secondary and tertiary consumers respectively.
