Organisms as different as penguins, cacti and zebras all share planet earth based on rainfall and temperature, they each occupy different habitats. The habitats that make up planet earth are oceans, wetlands, forest, grasslands, deserts, mountains, and polar habitats.
Planet Earth’s two biggest grasslands are the tropical African savanna and the temperate grasslands of North and South America. On land, if certain areas are too dry or wet, grasslands appear. Grasslands survive because many animals eat grass, which causes more grass to grow. A wide variety of animals live in the grasslands, including grass eaters zebras, wildebeest and those that prey on them like lions.
Oceans cover about 70 percent of the Earth’s surface. There are many ocean zones such as the twilight zone, the deep zone, and also the surface. The ocean’s zones have their own communities of organisms. Most living things in any ocean depend on phytoplankton, which are microscopic organisms that float near the ocean surface.
Another habitat, mountains, is hard to survive in because the higher you climb the thinner the air gets. Mountains have different elevations. Near the top of most mountains there is only bare rock and snow. Certain types of species live in different mountain zones. Deer and birds live in woodland forests. Rodents and rabbits often live in the meadows surrounding mountain bases.
Oceans, grasslands, and mountains all have unique habitats. Each has a wide variety of plants and animals. Planet Earth’s species range from the bottom of the oceans to the top of the mountains.
