Grasslands, located in semi-arid zones, contain wide, treeless expanses often inhabited by grazing animals. Sub-categories of grassland ecosystems include savannas, which are found in the tropics; prairies, situated in temperate regions; and steppes, which can be found in either climate.
With a drier climate than grasslands, desert ecosystems are characterized by relatively sparse vegetation, and the number of insects and animals is also relatively limited. Deserts aren’t necessarily hot; they can lie in temperate zones as well. Nor must they be sandy; many deserts feature rock floors.
Tundra ecosystems, located in polar regions or on the tops of high mountains, are frozen and snow-covered most of the year. Life is hard in these white, treeless swaths, but during the brief summer, snows may melt enough to expose lichens or small wildflowers and attract migrating birds.
