Chapter #31 EC O S Y S T EMS
Chapter 31.1 Notes • Ecosystem is a community interacting with the environment. Includes all the living and nonliving factors. • Biotic living factors plants, animals, fungi… • Abiotic nonliving factors soil, sunlight, air, water…. • Soil form from broken down rocks.
Ecology is the study of how living things interact with each other and with their environment. • Nitrogen is important because living things use it to make protein.
Cycles is the reusing of a natural resource. • Water cycle • Nitrogen cycle (plants get N mainly from the soil) • Oxygen-Carbon dioxide cycle
Chapter 31.2 Notes • Succession is the changes that take place in a community as it gets older. • Climax community is the last or final stage of succession.
Forest community succession… Bare soil, field of weeds, field of small plants, Forest
Chapter 31.3 Notes • Light and temperature are 2 nonliving (abiotic) factors that are not cycled. • Precipitation is water in the air that falls to the earth as rain or snow. • Climate is the average of light, temperature and precipitation over many of years.
Biome a land area with a distinct climate and with specific type of plants an animals. • Tropical rain forest- a lot of rain (200cm/year) about 6 feet. • Grassland- gophers are common • Desert -little precipitation and lizards • TemperateForest-biggesttemperaturerange • Taiga- moose are common • Tundra- polar bears…10-15cm of precipitation/year.
Temperate Forest Grasslands Taiga Desert Tundra Rainforest
Water Ecosystem • Salt water • Fresh water
