BIOMES OF THE WORLD

Ecosystems Ecosystems are defined in terms of natural landscapes, human designated boundaries on maps, water sheds, forests, mountains, grasslands, wetlands, deserts, rivers, lakes, oceans, seas, and estuaries. The Biosphere is the thin layer of water and soil where all living things are found. Ecosystems are a complex network of living and non-living things!

What makes up an ecosystem? Flora: plant life Fauna: animal life Abiotic- non living: temperature, humidity, elevation, precipitation, wind, light, shade, soil, water, sun Biotic- living organisms: plants and animals

Biodiversity Biodiversity is the number of different plant and animal life living in a defined ecosystem Niche refers to the interactions and relationships an organism experience, how it reproduces and where it obtains its food, water and shelter

Symbiosis Mutualism: A relationship between two species where both benefit Commensalism: A relationship between two organisms where one species benefits and the other is unharmed Predation: A relationship between two species with one being the predator and one being the prey Competition: involves interactions among affected organisms where limited resources are divided among competitors.

Biomes The major ecosystems of the world are classified into unties called biomes. Each Biome has a characteristic climate that directly influences its flora and fauna!

Forest Biomes Coniferous Deciduous Tropical Rain Forest

Limited Water Biomes Tundra Prairies Deserts Mountains

Fresh Water Biomes Ground water Standing water (Lakes and Ponds) Flowing water (Rivers and Streams)

Salt Water Biomes Oceans Sandy Beaches Intertidal Zone Barrier Islands Rocky Shores Tide Pools Wetlands Coral reefs
