1 Organisms and Where They Live

2 An ecosystem consists of living and nonliving things. The living things make up a community. The living things make up a community. Communities are divided into populations. Communities are divided into populations. A habitat is where an organism lives. A habitat is where an organism lives. The nonliving things that affect an ecosystem are: The nonliving things that affect an ecosystem are: light light soil or water, soil or water, amount of rain, amount of rain, altitude, and altitude, and temperature temperature

3 Things may harm an environment. Too many animals depleting resources for survival, and humans building homes on forest or desert land. Too many animals depleting resources for survival, and humans building homes on forest or desert land. There are ways that the ecosystem can be protected and improved. There are ways that the ecosystem can be protected and improved. Birds can eat insects that would harm the environment. Birds can eat insects that would harm the environment. Humans can set up wildlife preserves. Humans can set up wildlife preserves. Plants can prevent soil erosion. Plants can prevent soil erosion.

4 There are different kinds of ecosystems. Climate is a major factor that produces different kinds of ecosystems. Climate is a major factor that produces different kinds of ecosystems. The ecosystems closer to the equator are warmer than those further away from the equator. The ecosystems closer to the equator are warmer than those further away from the equator. The land ecosystems are: The land ecosystems are: taiga taiga grasslands grasslands mild forest lands mild forest lands desert desert tropical rain forest tropical rain forest tundra. tundra. The water ecosystems are: The water ecosystems are: saltwater shores saltwater shores freshwater rivers freshwater rivers freshwater lakes and ponds freshwater lakes and ponds open sea-surface open sea-surface open sea-deeper down open sea-deeper down

5 A food chain is the steps in which organisms get the food to survive. Producers, consumers, and decomposers are the three types of organisms that play a role in the community. Producers, consumers, and decomposers are the three types of organisms that play a role in the community. They are also involved in the food chain. They are also involved in the food chain. Producers make food. Producers make food. Producers are green and have chloroplasts. Producers are green and have chloroplasts. Consumers use the food that producers make or eat other organisms. Consumers use the food that producers make or eat other organisms. Consumers can be herbivores, carnivores, or omnivores. Consumers can be herbivores, carnivores, or omnivores. Decomposers break down wastes and other remains of organisms. Decomposers break down wastes and other remains of organisms. Decomposers are bacteria, fungi, worms and snails. Decomposers are bacteria, fungi, worms and snails. A food web consists of overlapping food chains. A food web consists of overlapping food chains. This is when organisms from different food chains share the same food source. This is when organisms from different food chains share the same food source.
