All the living and nonliving things in an area
A group of organism of one species that live in an area at the same time
All the populations in one area. Members depend on each other for food, shelter, and reproduction.
Nonliving Parts of an Ecosystem
Air, water, soil, temperature, and sunlight
Large ecosystem with the same climate and organisms. It may contain many countries. All biomes make-up a biosphere.
Community made up of trees such as spruce and maple. The climate is cool and wet. Animals include elk, raccoons and owls.
A role in an ecosystem.
A place where an organism lives
Receive large amounts of water. Holds the greatest number of species of any biome
Trees like oaks, elms, and maples lose their leaves. Snakes, bears, and frogs hibernate. Coloring changes to blend in with the environment.
Ecosystem covered with many types of grasses and few trees. Not a lot of rain. Animals such as bison, antelope and prairie dogs eat the grass. They are hunted by gray wolves and coyotes.
Trees have needles. Climate is cold and dry. Bears, elk, moose, wolves, porcupines, and wolverines are found here.
Climate is hot and dry. Some deserts have sand dunes and others are rocky. Rattlesnakes, lizards, jackrabbits, and beetles are some species found here
Very cold with little rain. Rodents, rabbits, caribou, weasels, owls, and fox are found here. There are small plants and grasses.
Limited amount of food, water, space, and shelter
Overcrowding will happen if a population grows larger than the carrying capacity
A wetland with tall sawgrass. Alligatores, fish, deer, and snakes are found here.
The place where rivers flow into oceans. Estuaries are salty, but not as salty as the ocean.
Grow in warm, shallow waters where the sunlight can reach. They provide homes for sharks, clams, crabs, and eels live here. They also protect shore lines from ocean storms.
Organisms that can deal with cold, dark water with no plant life. Organisms eat dead plants/animals that sink from higher levels.
Animals compete over space, territory, water, light, food, and mates
Plants compete for water and sunlight
Relationship between different species.
Three Types: The orangis may be helped, harmed, or not affected at all.
Make their own food for energy. They use sunlight and other chemicals in nature.
Cannot make their own food. They eat other organisms to get energy.
Consumers that eat plants only
Consumers that eat only other animals (predators)
Eat both plants and animals
A simple chain to show how energy flows through an ecosystem
A diagram that shows the amounts of energy that flow through each level of a food chain. Producers have the most energy.
Fungi, earthworms, flies, bacteria, banana slugs, slime molds, millipedes, and ants break down material in nature. Nutrients are released back in the soil for plants to use.
