Ecosystem Vocabulary

Producer
any of the plants and algae that produce oxygen and food that the animals need.
Ecosystem
All the living and non-living things in an area and their interactions with each other.
Decomposers
any of the fungi or bacteria that break down dead plant and animals into useful things like minerals and rich soil.
Fungi
members of a kingdom that contain one celled and many-celled living things that absorb food through their environment. A decomposer- mushrooms are an example.
Biome
one of Earth's large ecosystems, whit its climate, soil, plants, and animals.
Consumers
any animal that eats plants or eats other plant-eating animals.
Scavengers
a meat eating animal that feeds on the remains of dead animals.
Habitat
the place where a population lives.
Organisms
living things that are capable of reacting to stimuli, reproduction and growth.
Taiga

Elodea
is a perennial aquatic plant often called water weeds. Often used in aquariums.
Mustard

Sun
the source of all energy to our planet.
Symbiosis/Symbiotic
a relationship between two kinds of organisms over time.
Acid Rain
moisture that falls to the Earth after being mixed with wastes from burned fossil fuels.
Photosynthesis
the food making process in green plants that uses sunlight.
Germination
the sprouting of a seed into a new plant.
Individual

Population
all the members of one species in an area.
Community
all the populations living in one area.
Niche
the role an organism has in its ecosystem.
Desert
a sandy or rocky biome, with little precipitation and little plant life.
Food Chain
the path of the energy in food from one organism to another.
Food Web
the overlapping food chains in an ecosystem.
Energy Pyramid
An energy pyramid is the graphical representation of the levels (nutritional) by which the incoming solar energy is transferred into an ecosystem.
Competition
active demand by two or more organisms or kinds of organisms for some environmental resource in short supply
Deciduous Forest
a forest biome with many kinds of trees that lose their leaves each autumn.
Learned Behavior
a learned behavior is a behavior that was observed by an individual that they find it to be beneficial to them in some way.
Increased Nutrients
increased nutrients added to the environment can create algae blooms which can choke out existing organisms in an aquatic ecosystem.
Extinct
no longer exists. This organism will no longer be found alive on the earth.
Tropical Rainforest
a hot, humid biome near the equator, with much rainfall and a wide variety of life.
Endangered
a species threatened with extinction; broadly: anyone or anything whose continued existence is threatened.
Threatened

bacteria
helps in the natural recycling process, a decomposer.
Estuary
where fresh water and saltwater meet. (coastal area)
Biotic factors
living components of an ecosystem (the organisms) existence is threatened.
Primary consumers
use plants for energy (anything that eats plants) examples: deer, mice, rabbits, porcupines
Secondary Consumers
get their energy from primary consumers.
Tertiary Consumers
get their energy from secondary consumers.
Organisms
Living things
Conservation
sensible use of the earth’s resources to avoid harming the environment.
Interdependence
the relationship between plants and animals in an ecosystem.
