This document provides information about different ecosystems and biomes. It defines an ecosystem as the interactions between living and nonliving things in a place, and a biome as a large region with similar climate and organisms. It then describes several major biomes in more detail, including tundra, temperate forest, tropical rainforest, desert, savanna, grassland, and chaparral. Each biome section provides examples of characteristic plants, animals, climates, and locations.
Ecosystems and Biomes
- 1. Ecosystems and Biomes Module 12
- 2. Ecosystems Ecosystems are the interactions between the living things and the nonliving things in a place. In an ecosystem, the plants, animals, and other organisms rely on each other and on the physical environment – the soil, water, and nutrients, for example. Even though they are living in the same place, each species in an ecosystem has its own role to play. This role is called a niche. The niche for one species might be to climb trees and eat their fruit, while the niche for another species might be to hunt for small rodents. For a tree, a niche might be to grow tall and make food with the Sun’s energy through the process of photosynthesis. If the niche of two species is very similar, they might compete for food or other resources.
- 3. Biomes A biome is made of many similar ecosystems. An ecosystem is often much smaller than a biome, although the size varies. Biomes are large regions of the world with similar plants, animals, and other living things that are adapted to the climate and other conditions.
- 4. Biomes Biomes are large regions of the world with similar plants, animals, and other living things that are adapted to the climate and other conditions. Explore the links below to learn more about different biomes. Tundra Taiga Temperate forest Tropical rainforest Desert Grassland Ocean biome
- 6. Tundra Arctic Moss Arctic Fox Temperature never gets above 50 degrees F. Located near the Poles
- 7. Characteristics of Tundra Extremely cold climate Low biotic diversity Simple vegetation structure Limitation of drainage Short season of growth and reproduction Energy and nutrients in the form of dead organic material
- 8. Alpine Tundra Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. The growing season is approximately 180 days. The nighttime temperature is usually below freezing. Unlike the arctic tundra, the soil in the alpine is well drained Very Cold All Year High Elevation
- 9. Alpine Tundra Mammals: Arctic fox, mountain goats, sheep, elk Birds: grouselike birds, snowy owls, Harlequin duck Insects: springtails, beetles, grasshoppers, butterflies
- 10. Temperate (Deciduous) Forest Temperate forests occur in eastern North America, northeastern Asia, and western and central Europe. Well-defined seasons with a distinct winter characterize this forest biome. Moderate climate and a growing season of 140-200 days during 4-6 frost-free months distinguish temperate forests.
- 11. Temperate (Deciduous) Forest squirrels, rabbits, skunks, birds, deer, mountain lion, bobcat, timber wolf, fox, and black bear.
- 12. Tropical Rainforest Bamboo Hardwood trees Tropical birds: parrots Hot, humid and very rainy Found at 15 to 25 degrees latitude
- 14. Desert Cactus Lizards Snakes Owls Little rain Temperatures can vary widely Covers 12% of the earth
- 15. Four Major Types of Desert There are four major types of deserts: Hot and Dry Semiarid Coastal Cold
- 16. Savanna LOCATION: Savannas are comprised mostly of grasses and a few scattered trees. They cover half the surface of Africa, large areas of Australia, South America, and India. Savannas can result from climate changes, soil conditions, animal behavior, or agricultural practices. Humans create savannas by burning grasslands and cutting down trees so they can plant crops. Elephants destroy trees and trample seedlings.

- 18. Grasslands
- 19. Grassland Grasslands are characterized as lands dominated by grasses rather than large shrubs or trees. There are two main divisions of grasslands: tropical grasslands, called savannas, and temperate grasslands.
- 20. Chaparral
- 21. Chaparral The chaparral biome is found in a little bit of most of the continents - the west coast of the United States, the west coast of South America Lay of the land: The chaparral biome has many different types of terrain. Some examples are flat plains, rocky hills and mountain slopes. It is sometimes used in movies for the "Wild West". Chaparral is characterized as being very hot and dry. As for the temperature, the winter is very mild and is usually about 10 °C. Then there is the summer. It is so hot and dry at 40 °C that fires and droughts are very common

Editor's Notes
- #2: Grasslands (Basic) Note: This template is optimized for PowerPoint 2010 and uses a video background. If used in PowerPoint 2007, video elements will play, but all content will be covered by video background when in slideshow. If used in PowerPoint 2003, video will not play, but the poster frame of the videos will remain in place as a static image. The video: Plays automatically after each slide transition. Is 30 seconds long. Seamlessly loops for infinite playback. To add slides or change layout, do the following: To add a new slide, on the Home tab, in the Slides group, click the arrow under New Slide, then click under Motion Background Theme select the desired layout. To change the layout of an existing slide, on the Home tab, in the Slides group, click Layout, then select the desired layout. This template uses the “Pushpin” Theme Font. To access or change the Theme Font, do the following: On the View tab in the Master Views group, select Slide Master. In the Slide Master view, select slide 1 (the Master Slide for Master Layouts that use the video background). On the Slide Master tab, in the Edit Theme group, click Fonts, and then select new theme fonts. Using animated elements: Any animated element will begin after the slide transition and the background video has started.
