According to Blue Planet Biomes, the temperate grassland food chain includes plants, insects and a wide range of larger animals that work together to meet the needs for energy within the ecosystem. The temperate grassland food chain begins when a producer is consumed.
According to Georgia State University's HyperPhysics, an autotroph, or producer, is an organism that produces food using energy sources such as the sun, soil or surrounding nutrients to survive. Grass and trees are examples of autotrophs. The food chain begins when insects and other animals eat these producers. The birds, small animals and omnivores that consume producers are called heterotrophs.
Grasslands are located on most of the continents. Each region has a unique variety of flora and fauna that builds the food chain. Temperate grasslands are comprised of flat plains with tall grasses that house a wide variety of insects and smaller animals such as rodents.
According to ScienceDaily, the food chain begins with producers and ends with the predators at the top of the food chain. Some common grassland predators include bears and cougars in North America, lions in Africa and wolves in South America. Scavengers, animals that work to remove any food left behind by predators, are also at the top of the food chain. Types of scavengers living in the grasslands include hyenas, vultures and flies.
