Organisms in a Midwestern Grassland Biome – PowerPoint Presentation

Midwestern Grassland Biome

  • žBiome is a grassland expanse in Midwest
  • žBiome has tall grass prairie
  • žBiome is moderately dry\
  • Soil is rich in minerals
  • Temperature ranges from 45°C to -40°C

The Midwest is a distinct geographical region characterized by the USA Census Bureau. It is in  the northern central region of the US.

The biome has tall grass prairie in a mid latitude area from 55° N to 30° S.

The biome is moderately dry with most rains in early summer and late spring.

The soil in the biome is rich in minerals with prairie grass roots  holding soil together firmly. The plants in the area have deep roots to survive dry conditions.

The average temperatures in the biome range from 45°C during hot summers to  about −40°C during winter.

Midwestern Grassland Biome

  • žBiome has mesic prairie
  • Biome is usually humid
  • Marked temperature variations
  • žSummer and spring have thunderstorms
  • žChinook winds moderate temperatures

The biome has mesic prairie, which is defined by good drainage and arable soils. It is good for farming. The biome is usually humid as it has a humid continental climate. There are marked temperature variations; very hot summers and very cold winters. The summer and spring are defined by thunderstorms, some of which are violent. Chinook winds flow through the biome, moderating temperatures especially during winter.

Organisms in the Biome

Cottonwood  has a symbiotic relationship with the other plants in the biome: Elm, Cranberry Viburnum, Gray Dogwood, and Common Chokecherry. Cottonwood uses the nutrients added to the soil by the decaying tissues of the other plants. The other plants use the nutrients added to the soil by the decaying tissues of cottonwood. Cottonwood  has a symbiotic relationship with the animals in the biome.

Cottonwood uses the nutrients added to the soil by the decaying tissues of the animals. The animals use cottonwood for camouflage and shade.

Cottonwood grows well in temperatures of over -43°F and under 46° C and has a limited tolerance to limited water conditions. It thrives in coarse, fine or medium soils (Denver County  Extension Master Gardener, 2010).

Elm has a symbiotic relationship with the other plants in the biome: Cottonwood, Cranberry Viburnum, Gray Dogwood, and Common Chokecherry. Elm uses the nutrients added to the soil by the decaying tissues of the other plants. The other plants use the nutrients added to the soil by the decaying tissues of Elm. Elm has a symbiotic relationship with the animals in the biome. Elm uses the nutrients added to the soil by the decaying tissues of the animals. The animals use elm for camouflage and shade.

Elm thrives in tropical-montane and temperate climates and has a limited tolerance to limited water conditions. It thrives in coarse, fine or medium soils (Elmcare.com , 2015).

Cranberry Viburnum has a symbiotic relationship with the other plants in the biome. Cranberry Viburnum uses the nutrients added to the soil by the decaying tissues of the other plants. The other plants use the nutrients added to the soil by the decaying tissues of Cranberry Viburnum. Cranberry Viburnum has a symbiotic relationship with the animals in the biome. Cranberry Viburnum uses the nutrients added to the soil by the decaying tissues of the animals. The animals use Cranberry Viburnum for camouflage and shade.

Cranberry Viburnum has a limited tolerance to limited water conditions. It thrives in coarse, fine or medium soils.

Gray Dogwood has a symbiotic relationship with the other plants in the biome. Gray Dogwood uses the nutrients added to the soil by the decaying tissues of the other plants. The other plants use the nutrients added to the soil by the decaying tissues of Gray Dogwood. Gray Dogwood has a symbiotic relationship with the animals in the biome. Gray Dogwood uses the nutrients added to the soil by the decaying tissues of the animals. The animals use Gray Dogwood for camouflage and shade.

Gray Dogwood has a limited tolerance to limited water conditions. It thrives in coarse, fine or medium soils.

Common Chokecherry has a symbiotic relationship with the other plants in the biome. Common Chokecherry uses the nutrients added to the soil by the decaying tissues of the other plants. The other plants use the nutrients added to the soil by the decaying tissues of Common Chokecherry. Common Chokecherry  has a symbiotic relationship with the animals in the biome. Common Chokecherry uses the nutrients added to the soil by the decaying tissues of the animals. The animals use Common Chokecherry for camouflage and shade.

Common Chokecherry has a limited tolerance to limited water conditions. It thrives in coarse, fine or medium soils.

Bison has a symbiotic relationship with the plants in the biome. The plants use the nutrients added to the soil by the decaying tissues of bison. Bison uses the plants for food, camouflage, and shade.

Bison thrives on plains, river valleys and prairies. It thrives in open grasslands, sagebrush, scrublands and semiarid lands. They can live 8,000 feet above the sea level. They eat grass and scrubs.
