Prairie Infographic

By: Arvind and Varun


Average Temperature During The Summer: 70° F

Average Temperature During The Winter: 20° F

Annual Precipitation: 10-30 inches

Examples and Regions

Regions Where Prairies Are Located: 55° N to 30° S area, Great Plains, North Central Plains, West Canada, Manitoba

Limiting Factors

Overcrowding: If coyote population goes up, the overhunting of smaller mammals, which will eventually lead to their starvation, which means the prey population will go up.

Diseases: Since animals populations in prairies are packed close together disease can spread quickly.

Natural Disasters: Tornadoes and other disasters could upset the balance of the food chain which could upset the natural balance of the ecosystem.

Human interaction: Human activity is what limits the expansion of the biome and can limit the parameters of the area animals can occupy.

General Range of NPP

Range: 2000-3000 (Kilocalories / square meter / year)

Explanation: The organisms in the prairie biome biome annually accumulate 3000 kilocalories per square meter

  • They have brownish skin color to blend into surroundings.
  • Are nocturnal to avoid predators.
  • Sharp claws and teeth allow them to dig though dirt easily.

Current Issues

  • Global Warming could cause prairies to become deserts
  • Urban expansion reduces the are of parries
  • Lack of plant diversity can increase risk for disease
  • GMOS have expanded into and taken over prairies

Biome Importance

  • They provide habitats for many animals and plants.
  • Grow healthy crops to feed animals.
  • Provide thousands of products to feed animals.
  • The plants improve water quality.
  • Produce some of richest soil in the world
