  1. BIOMES Earth can be divided into geographic regions based on climate. The kind of climate that develops is called a biome. There are two types of biomes: Terrestrial Biome – land based Aquatic Biomes – water based Mrs. Degl

  2. Biomes of the world Mrs. Degl

  3. Terrestrial Biomes • Major land plant and animal biomes are determined by climate zones. • Climate zones are determined mostly by geographic factors like latitude and altitude. • Location to large bodies of water, mountain ranges, and deserts also modify climate. • A regions climate includes the temperature range, the average amount of precipitation it receives, and the amount/angel of solar radiation it receives over the course of a year. Mrs. Degl

  4. Terrestrial Biomes are named for the kind of climax vegetation found there. The table below describes the 6 major land biomes. They are the Tundra, Taiga, Temperate Forest, Tropical, Grassland, and Desert. Mrs. Degl

  5. Effects of Latitude and Altitude on Land Biomes Mrs. Degl

  6. Aquatic Biomes • Aquatic Biomes make up the largest ecosystem on Earth. • More than 70 % of the Earth’s surface is covered in water. • Most living things are water dwellers. • Aquatic Biomes are more stable than Land Biomes, b/c of less variation over time. • Water temperature, % dissolved O2 and CO2, intensity of light, and dissolved minerals all effect life in the water. Mrs. Degl

  7. Marine Biomes • These are made of saltwater • This includes all of the oceans on the Earth, which is really one big body of water. • Oceans have the most stable biome on Earth b/c water absorbs/releases heat very slowly, has a large variation of organisms, has a constant supply of nutrients, and is where most of the planet’s photosynthesis occurs. Mrs. Degl

  8. Freshwater Biomes • Freshwater is defined as having a low salt concentration (less than 1%). • Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration. • Freshwater biomes include ponds, lakes, rivers and streams, and wetlands, which are all very different. • Ponds and lakes tend to fill over time, b/c dead plants and sediment accumulate on the bottom. • Wetlands are areas of standing water that support aquatic plants. Marshes, swamps, and bogs are all wetlands. Mrs. Degl
