MAIN TYPES OF ECOSYSTEMS


There are many different types of ecosystems on Earth.
We can classify them into:
A.- Terrestrial ecosystems:
  • Forests: forests have lots of trees. These provide food and shelter for animals.
  • Grasslands: grasslands have lots of grass. Large herbivores eat the grass.
  • Deserts: there are not many plants and animals in deserts because it does not rain very much.
B.- Aquatic ecosystems:
  • Freshwater ecosystems: These are found in rivers, streams and lakes. Rivers and streams have moving water. Lakes have still water.
  • Saltwater ecosystems: These ecosystems are in the sea. They are found on the coasts, in coral reefs and in the open sea.
