Temperate Grassland Biome
Transcript of Temperate Grassland Biome
The temperate grassland biome is found in the middle of the United States, the central/south area of South America, half of Asia, most of Africa, half of Europe, and most of Australia.
A biotic factor is a living factor in the environment. Some examples of biotic organisms in temperate grasslands are blue eyed grass, chipmunks, african bush elephants, cattails, indian grass, black oat grass, wood betony, zebras, antelopes, and prarie dogs.
An abiotic factor describes the nonliving part of the environment, including water, rocks, light, and temperature. In temperate grasslands, temperature (a summer high of 100 degrees F and a winter as low as -40 degrees F.), rainfall (moderate rainfall occurs in late spring and early summer with a yearly average of 10-35 inches), the soil (having the most richest soils in the world, used for farmland), fires (keeps the grasslands full of short plants instead of trees and shrubs), and droughts (not having enough of water per year to be able to support living trees), are all examples of abiotic factors in temperate grasslands.
A problem with the resources in temperate grasslands are the overgrazing by livestock. With this problem, there could eventually not be enough resources/food for the organisms. This could cause an organisms population to drop, or even die out. It could cause an obstacle in the food web. This can happen when there are too many animals in a certain area.

Competition is when two or more individuals or populations try to use the same resource, such as food, water, shelter, space, or sunlight. An example of competition in temperate grasslands is foxes and hawks fighting for rabbits
Predation is the act of killing and eating other animals (the act of preying on other animals.) An example of predation is an owl and a small mammal.
This act of predation is done by the owl (predator) eating the mouse (prey).
Parasitism is the relation between two different types of organisms in which one benefits from the other by causing damage to it. An example of parasitism in temperate grasslands is ticks or fleas fending off any number of animals, including lions and wolves.
Commensalism is an association between two organisms in which one benefits and the other neither benefits or gets harmed. An example of commensalism in temperate grasslands is when a killdeer bird rests on top of a cape buffalo.
no harm to cape buffalo; rest for killdeer

Mutualism is a relationship between two species of organisms in which both benefit from the association. An example of mutualism in temperate grasslands is when bees pollinate flowers and then flowers return the favor by feeding the bees.
Bees pollinate the flowers while the flowers are feeding the bees.
There is a very big concern for the remaining grasslands in temperate regions. Since the soil is incredibly rich, land is flat, and barely any trees, farmers are starting to turn the land into ranches and farms. These practices are a fragmentation of once large tracks of grasslands. Fragmentation can decrease biodiversity, (the variety of life in a particular habitat or ecosystem). The practices can also cause wind to form dust storms.
Also, in dry areas, overgrazing and the build-up of salt can cause the areas to turn into near-wastelands. These issues can ruin the environment and endanger the ecosystem.
Other names: prairie, pampas, steppe, outback, high veld, campo
They have some of the richest soil.
They have two seasons: a growing season and a dormant season.
Fires, both natural and human-caused are important to maintaining the grasslands.
Temperate grasslands are found on every continent except for Antarctica.
