Ecosystems
5.L.2
Understand the interdependence
of plants and animals with their
ecosystems.
5.L.2.1
Compare the characteristics of several common
ecosystems, including estuaries and salt marshes,
oceans, lakes and ponds, forests and grasslands.
Essential Questions
• What are ecosystems?
• What is the relationship between living
things in an ecosystem?
• How does human interaction affect
ecosystems?
Ecosystem
• Everything that exists in a particular
environment.
• An ecosystem includes living things,
such as plants and animals, and things
that are not living, such as rocks, soil,
sunlight, and water.
Two Different Kinds of Ecosystems
1. Terrestrial – land-based; include forests
and grasslands.
– Forests have many trees (with needles or with
leaves), shrubs, grasses and ferns, and a variety
of animals. They usually get more rain than
grasslands. Diverse types of animals can be
found in forests, depending on their type
– Temperatures in forests will vary based on
where they are located in respect to the equator.

Two Different Kinds of Ecosystems
2. Aquatic – water-based ecosystems may be
freshwater (lakes and ponds) or saltwater
(oceans, estuaries and saltwater marshes).

Lakes and ponds are bodies of freshwater
surrounded by land.

Ponds – more shallow than lakes; temperature is
usually the same from top to bottom.


Plants and algae usually grow along the edges where the
water is shallow.
Various fish, amphibians, ducks, turtles, or
beavers…
• Oceans are large bodies of saltwater divided
by continents.
