Savannas are warm year-round. Flat, treeless meadows without forests. Many mammals, reptiles, and insects live in equatorial savannas. Meerkats, termites, elephants, crocodiles, and snakes inhabit savannas.
Cold Tundra. This semi-flat, treeless landscape has frozen drainage. Animals winter migrate. Caribou and semipalmated plover winter migrate. This ecosystem only has arctic hare and polar bear.
Wetlands are flooded areas. It can be beside a lake, pond, marsh, or river mouth. Wetlands can be oceanfront. A saltwater or freshwater-soaked place. Birds, reptiles, and invertebrates live in wetlands.
Warm, wet, plant- and animal-filled rainforests. This occurs worldwide. Brazil and Costa Rica have jungles. Rainforest trees climb for sun. Rainforests are home to jaguars, poison frogs, and gorillas.
Arctic features glaciers and tundra. The cold climate limits the kind of animals that can live. In the freezing biome reside narwhals, penguins, walruses, and polar bears.
Coral reefs form near tropical islands and continents. Microscopic water critters build coral reefs, which shelter many species. Coral reefs shelter sharks, eels, and snappers. Reefs host crustaceans and sponges.
Grasslands have a middle-of-the-road rainfall proportion. Predominantly grass. Trees require more water. Grasslands sit between deserts and mountains. Ecosystem animals include grazers and predators.
Fresh water defines river and stream habitats. Freshwater is home to fish and other animals. Rivers and streams have marsh birds, turtles, snakes, and otters. Alligators and beavers inhabit water.
Deserts aren't always scorching and dry. Others are cold and semi-arid. Coastal deserts exist. These areas have low annual precipitation. Snakes, mice, armadillos, and ants can be found in deserts.
