Study Guide for Habitats (3.6)
*A POPULATION is a group of organisms of the same kind that live in the
same place.
*A COMMUNITY is all of the populations that live together in the same
place.
*WATER-RELATED ENVIRONMENTS include those with fresh water and
salt water. Examples include ponds, marshes, swamps, streams, rivers, and
oceans.
*DRY-LAND ENVIRONMENTS include deserts, grasslands, rain forests,
and forests.
*OCEANS are Earth’s largest ecosystem. They make up three-fourths of
Earth.
*Oceans and seas contain SALT WATER.
*Rivers, ponds, and streams contain FRESH WATER.
*A DESERT is an area that gets very little rainfall.
*An area in which the main plants are trees is called a FOREST.
*A forest growing in a hot, rainy place is a TROPICAL RAIN FOREST.
*Everything around a plant or animal is its ENVIRONMENT.
*A forest of trees that form seeds in cones is a CONIFEROUS FOREST.
*A forest of trees that lose and regrow their leaves each year is a
DECIDUOUS FOREST.
*The living and nonliving things that surround a living thing make up its
ENVIRONMENT.
*The place in an ecosystem where a population lives is its HABITAT.
*An ECOSYSTEM is made up of all the living and nonliving things in an
environment.
*DESERTS are very dry ecosystems.
*GRASSLANDS are dry, often flat areas of land that are hot in the summer
and cold in the winter.
*The three layers of the rain forest are CANOPY (top), UNDERSTORY
(middle), and FOREST FLOOR (bottom).
**How can damage to an ecosystem harm animals that live there? *Damage
may kill living things in an ecosystem; damage may force living things to
move to other ecosystems.
**Nonliving things are part of an ecosystem. Why is this important?
*Nonliving things provide some of the needs of living things.
