ecosystem Flashcards
This is an organism that is made of many parts but cannot make its own food. They are classified by whether they have a backbone or not.
Animal
This is the type of biome that is found in the water.
Aquatic
One celled organism that reproduces by fission.
Bacteria
This is an organism that relies on other organisms for its food and energy supply; also called a heterotroph.
consumer
This is an organism that breaks down and gains nutrients from dead organisms.
Decomposers
Biotic and abiotic factors interacting within the setting of a community.
Ecosystem
The capacity for doing work. It may be transformed from one form to another.
Energy
The thin zone along a coastline where freshwater systems and rivers meet and mix with a salty ocean (such as a bay, mouth of a river, salt marsh, lagoon).
Estuary
This is any substance we eat or drink to maintain life and grow.
food
This is a path for the transfer of matter and energy through an ecosystem by eating and being eaten.
food chain
This is a terrestrial ecosystem that has many trees, either with leaves or needles or both.
forest
This type of water has a very low salt content when compared to the ocean.
freshwater
This is the kingdom of heterotrophs that obtain energy and nutrients from dead and decaying organic matter.
fungi
A biome where grasses are the main vegetation, usually mixed with herbs and sometimes with shrubs, but usually without trees.
Grassland
This is a natural or man-made body of water that can form when a depression on Earth fills with water.
lake
This is a low, poorly drained section of land, that may not always be covered in water.
marsh
This is a place where some young organisms are born and often spend the first parts of their lives. It is usually safer here than in an adult environment.
Nursery
This is a large body of water covering most of the earth.
ocean
This is a chemical process that uses light to process carbon dioxide in plants.
photosynthesis
