Biomes Weather & Climate • Weather: The condition of the atmosphere day-to-day. • Climate: The average year-to-year conditions. 3 Main Climates on Earth 1. Polar 2. Temperate 3. Tropic Climate zones are determined by differences in latitude and the tilt of the Earth. (changes the angle of heating) Biotic & Abiotic Factors in the Ecosystem • Bio = Life • A = Not • Biotic factors: Living things • Abiotic factors: Nonliving things Biotic and Abiotic Factors in an Ecosystem Abiotic Factors Biotic Factors ECOSYSTEM Biome a major regional terrestrial community with its own type of climate, vegetation, and animal life Can all kinds of organisms live in every biome? NO! Species are adapted to survive in certain biomes. Adaptation: an inherited condition that increases an organism’s ability to survive and reproduce. Who lives where? Climate is important! 1. 2. 2 main factors of climate: Temperature Precipitation A “Climatogram” (climate diagram) shows temperature and precipitation for an area Microclimate: climate in a small area that is different from the climate around it. Practice with Graphs Practice with Graphs Think and Share: Water Cycle Describe how the water cycle is different in the desert biome from the water cycle in the Virginia biome. Think about this and then share with your table. Rain Shadow Effect
