Ecosystems

DefinitionTerm
Made up of all the living and non living things in an environment. Ecosystems
Organisms can be categorized as _______, _______, and ______. Producers, Consumers, Decomposers
Organisms that make their own food using the Sun's energy (plants). Producers
Organisms that must eat other organisms to survive. These include herbivores (plant eaters), carnivores (meat eaters), omnivores (which each plants and animals), and scavengers (which eat the leftover meat from a prey that another animal killed) Consumers
Organisms that break down dead matter. Decomposers
The animals that hunt to eat. Predators
The maximum amount of plants and animals that an area can support. Carrying Capacity
Feeds on and harms a host organism. Parasite
A characteristic that helps an organism to survive in its environment. Adaptation
A change in an organism's behavior, like wolves hunting in packs to take down large animals, or fish in swimming in schools for protection. Behavioral Adaptation
Refers to an organism's physical structure, like a giraffe's long neck which helps it reach leaves on tall trees, or cacti having a thick, waxy cuticle that prevents water loss so it can survive in a dry environment. Structural Adaptation
Allows an animal to blend in with its background, like the way that arctic foxes and rabbits have fur that turns white in the winter so they can blend in with the snow. Protective Coloration
Means the animal has the same color AND shape of its environment, like a stick bug. Protective Resemblance
The living organisms in an ecosystem (plants and animals). Biotic Factors
The nonliving features in an ecosystem (Sun, water, soil). Abiotic Factors
Mean things that happen in nature without human interference, like storms or floods. Natural Events
A treeless plain in the arctic regions where the ground is frozen all year long. Tundra
Good for farming because the soil is so rich in nutrients. Grasslands
Have abundant rainfall, making them very wet environments. Tropical Rainforests
Human-caused pollution, like ___,________,and _____, can pollute soil and freshwater systems. Oil, Pesticides, Trash
Like lakes and ponds, ______ and ______ are freshwater ecosystems, but they are different because they have moving water. Rivers and Streams
Show the path of energy as it flows through an ecosystem. Food Chains
Show how food chains overlap in an ecosystem. Food Webs
Coastal Louisiana has many _______ because it is where the Mississippi River flows into the Gulf of Mexico. Wetlands
About __% of the wetlands in the U.S. are located in Louisiana. 40%
_______ can help keep animal populations in balance. Hunting
______ are the animals that are hunted. Prey
Only eat meat. Carnivores
Only eat grass and plants. Herbivores
Eat both plants and meat. Omnivores
organisms that make their own food using the Sun's energy (plants) Producers
organisms that must eat other organisms to survive Consumers
organisms that break down dead matter Decomposers
animals that hunt to eat Predators
animals that are hunted Prey
the maximum amount of plants and animals that an area can support Carrying Capacity
feeds on and harms its host organism Parasite
a change in an organism's behavior that helps it survive Behavioral Adaptation
an organism's physical structure that helps it survive in its environment Structural Adaptation
when an animal is the same color as its background (camouflage) Protective Coloration
when an animal has the same color AND shape of its environment Protective Resemblance
living organisms in an ecosystem Biotic
nonliving features in an ecosystem Abiotic
when things happen in nature that are not caused by humans Natural Events
a treeless plain in the arctic regions where the ground is frozen all year long Tundra
lands covered with grasses that are good for farming because the soil is so rich in nutrients Grasslands
abundant rainfall, which makes them very wet environments Tropical Rainforests
Name 4 examples of freshwater ecosystems. lakes, ponds, rivers, and streams
Name 3 examples of human-caused pollution. spilled oil, pesticides, trash
