A biome is made up of many generally similar ecosystems that have generally similar producer species, soil and climates in a geographic area. These unique biomes support different varieties of organisms. Terrestrial biomes include tundra, taiga, grassland, desert, temperate deciduous forest, savanna and tropical rainforest. Aquatic biomes include estuary, freshwater and marine.
Terrestrial ecosystems are land-based and include tropical rain forests, savanna, temperate forest, mountain, taiga, tundra, grasslands, and deserts.
Aquatic ecosystems are water-based and include freshwater (lakes and ponds), as well as salt water (marine, estuaries, and marshes).
