Biomes

Tropical Rainforests

Biomes located near the equator characterized by high temperatures, high rainfall, and high biodiversity.

Temperate Forests

Forests found between 30° and 60° latitudes that experience well-defined seasons, including a distinct winter.

Temperate Deciduous Forests

Forests with cold, dry winters and hot, humid summers where trees shed leaves in winter to conserve energy.

Temperate Rainforests

Forests with mild, frost-free winters and evenly distributed rainfall throughout the year.

Coniferous Forests

Also known as boreal forests or taigas, these are found between 50° and 60° north latitudes, featuring short summers and long, cold winters.

Deserts

Arid regions typically found around 30° north and south of the equator, characterized by low and variable rainfall and specialized plants for water conservation.

Grasslands

Biomes that can occur at any latitude, experiencing seasonal drought and grazing, with types including savannas and temperate grasslands.

Scrublands

Also known as shrublands or chaparrals, these are located in coastal regions between 30° and 40° latitudes, dominated by shrubs and short trees.

Tundra

A cold, dry biome primarily in the arctic, characterized by permafrost and low biodiversity, with a short growing season.

Aquatic Biomes

Water-based ecosystems influenced by dissolved oxygen and nutrient concentrations, including freshwater and marine environments.

Freshwater Biomes

Aquatic ecosystems with little or no salt, including ponds, lakes, streams, and rivers, vital for drinking water.

Littoral Zone

The shallow, near-shore layer of a lake with abundant sunlight and nutrients, supporting diverse plant and animal life.

Limnetic Zone

The sunlit surface layer of a lake where photosynthesis occurs, supporting phytoplankton, zooplankton, and freshwater fish.

Profundal Zone

The deep-water layer of a lake, too dark for photosynthesis, cooler, and with less dissolved oxygen, supporting specialized fish.

Benthic Zone

The bottom layer of a lake, inhabited by decomposers and organisms that feed on dead material, often in low-oxygen conditions.

Source Zone

The headwaters of a stream or river, characterized by cold, fast-moving water with high dissolved oxygen and low nutrients.

Transition Zone

The area where headwaters merge, featuring wider, slower-moving water with more sediment and a greater variety of life.

Floodplain Zone

The flat area where a river spills over its banks, containing warm, nutrient-rich waters that support diverse plant and animal life.
