Biome

Geographic areas with ecosystems that share similar abiotic and biotic factors.

Desert

A land biome with very little rain, usually hot and dry, covering 1/3 of Earth's land.

Grasslands

Biomes dominated by grasses that act as carbon sinks and are rich in invertebrates.

Tropical Rainforest

Biomes near the equator characterized by heavy rainfall and high biodiversity.

Temperate Rainforest

A biome located between the tropics and polar circles with a mild climate and distinct seasons.

Temperate Deciduous Forest

A common biome in the US with seasonal variations where trees lose leaves in fall.

Taiga

A forest biome with coniferous trees in northern regions, colder with fewer reptiles and amphibians.

Tundra

A cold, dry, treeless biome with frozen ground, housing many furry mammals.

Aquatic Biomes

Biomes that depend on abiotic factors such as temperature, sunlight, and dissolved oxygen.

Wetlands

Biomes with a thin layer of water over soil, nutrient-rich and biodiverse.

Estuary

A biome where freshwater meets saltwater, home to brackish water and diverse marine life.

Open Ocean

A biome that starts from the continental shelf, rich in algae and supporting diverse marine life.

Intertidal Zone

The area between tidal lines where organisms adapt to varying moisture, oxygen, and salinity.

Coral Reef

Shallow tropical biomes structured by coral, known for their high biodiversity.

Ecosystem Services

The benefits provided by ecosystems, including supporting, provisioning, regulating, and cultural services.

Supporting Services

Necessary ecosystem functions that support all life, such as nutrient cycling.

Provisioning Services

Economic benefits derived from ecosystems, including food, freshwater, and resources.

Regulating Services

Benefits gained from the regulation of ecosystem processes, like pollination and climate regulation.

Cultural Services

Benefits obtained from experiences with ecosystems, including recreation and economic opportunities.
