Study Notes
Biomes on Earth
- Biomes are major terrestrial and aquatic ecosystems that support a wide range of plants and animals.
Terrestrial Biomes
- There are three main types of terrestrial biomes: rainforest, desert, and grassland.
Rainforest Biomes
- Rainforests are characterized by high temperatures, high humidity, and heavy rainfall.
- There are two types of rainforests: tropical and temperate.
- Tropical rainforests are found near the equator and have a diverse range of plant and animal species.
- Temperate rainforests are found in cooler regions and have a more limited range of species.
Parts of a Tropical Rainforest
- A tropical rainforest consists of four layers: emergent layer, canopy layer, understory layer, and forest floor.
Threats to Rainforests
- Rainforests are threatened by deforestation, habitat fragmentation, and climate change.
Desert Biomes
- Deserts are characterized by low rainfall, high temperatures, and limited vegetation.
- Examples of desert biomes include the Sahara Desert, Mojave Desert, and Gobi Desert.
Threats to Deserts
- Deserts are threatened by climate change, overgrazing, and human activity.
Grassland Biomes
- Grasslands are characterized by temperate climates, low rainfall, and limited vegetation.
- Examples of grassland biomes include savannas, prairies, and steppes.
Threats to Grasslands
- Grasslands are threatened by habitat fragmentation, overgrazing, and climate change.
Tundra Biome
- Tundra is a cold, treeless biome found in Arctic and sub-Arctic regions.
- The tundra is threatened by climate change, habitat fragmentation, and human activity.
Marine Biomes
- Marine biomes include coral reefs, estuaries, and open ocean ecosystems.
- The ocean biome is the largest ecosystem on Earth, covering over 70% of the planet.
Coral Reefs
- Coral reefs are found in shallow, tropical waters and are characterized by a diverse range of marine life.
Threats to Marine Biomes
- Marine biomes are threatened by climate change, pollution, and overfishing.
Freshwater Biomes
- Freshwater biomes include rivers, lakes, and wetlands.
- Freshwater biomes are threatened by habitat fragmentation, pollution, and human activity.
