Science Chapter 3 Study Guide

-A producer makes food from,water,air,and sunlight. Plants are producers.

-Animals that hunt other animals for food are called predators.

-A worm may become the prey of a bird.

Fungi and bacteria are decomposers. Decomposers are organisms that break down dead plant and animals.

-An organism that lives on or inside another organism is a parasite. It can make the host sick or cause death.

-A consumer eats producers.

-All living things live close to their habitat. An ecosystem is all the living and nonliving things in a place.

-Producers and consumers make up the food chain.

-A community is all the living things in an ecosystem.

-Population is all the members of a single type of an organism in an ecosystem.

-Plants and and animals can be broken down by decomposers.

-Plants are the only producers.

An owl and a hawk are not in the same food chain because one does not need the other as food.

-The habitat of a fish must include water.

-An example of a host and a parasite is a dog and a tick. The dog is the host for the tick which is the parasite.

-There will always be more plants at the bottom of a food pyramid to support the other consumers of the pyramid.

-An ecosystem are all the living and nonliving things in an environment and their interactions,

-A food web is several food chains that are connected.

-If all the water in an ecosystem disappeared, plants and other living things need the water to live. The food chains would disappear.

-Animals are part of the carbon dioxide and oxygen cycle because they give off carbon dioxide and take in oxygen,

-Predators help scavengers. The predator kill the prey. The scavengers eat what is left over. Without predators, scavengers would go hungry.

-To test your hypothesize that leaves will decompose more quickly in the sun than in the shade you could place leaves into two glass bowls partly filled with soil. Place one in the sun and one in the shade. Check the bowls every two days and record the results.
