Lesson 1 - Where Do Organisms Live?
Science Background
There are many different kinds of
habitats, each inhabited by different
kinds of organisms. Organisms often
compete with one another for resources
such as water, food, or space in a habitat.
For example, predators such as coyotes,
hawks, and snakes may compete for prey
food resources such as rabbits and mice.

Science Background
A tropical rain forest and a desert are
examples of terrestrial habitats. A tropical
rain forest is characterized by high
temperatures and precipitation almost every
day. Deserts receive little rain. Many, but
not all, deserts are hot during the day and
very cool at night.

· A wetland is land that is covered with water
at least part of the year. Ponds, swamps,
and marshes are examples of wetlands.

Lesson 1 - Where Do Organisms Live?
Science Background
· All the things that surround an organism
make up its environment. The environment
encompasses a larger area than a habitat.
There can be many different habitats in an
environment.
· Organisms change their environment in
different ways. When beavers build dams or
groundhogs dig tunnels, they are changing
their environment.
