Ecosystems

What is an ecosystem? • Ecosystem is a system of living things that interact with each other and with the physical world. • A Biome is a collection of related ecosystems.

Main Ecosystems: • • Desert Rainforest Ocean Taiga • • Tundra Chaparral Grassland Temperate Forrest

Major Biomes

Savanna comprised mostly of grasses and a few scattered trees. They cover half the surface of Africa, large areas of Australia, South America, and India.

Chaparral • vegetation consisting chiefly of tangled shrubs and thorny bushes.

Tropical Forest • The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm. ) of rain falls yearly.

Temperate Broadleaf Forest • In regions where rainfall is broadly distributed throughout the year, deciduous trees mix with species of evergreens. Species such as oak, beech, birch, and maple.

Temperate Grasslands • The most important plants in this biome are grasses! Temperate grasslands have some of the darkest, richest soils in the world.

Ocean Zones

Estuaries • Where fresh water from rivers mixes with salt water from the sea.

However……. . • An ecosystem can be as large as the Sahara Desert, or as small as a puddle!!! • Ecosystems are more than just the organisms they contain. Geography, weather, climate and geologic factors also influence the interactions within an ecosystem.

Balance n Ecosystems will fail if they do not remain in balance. n No community can carry more organisms than its food, water and shelter can accommodate.
