Ecosystems 1
a non-living factor
What is abiotic?
A living factor
What is biotic?
A place where an organism lives; its "address"
What is a habitat?
All energy in food webs comes from this
What is the sun?
An organism's functional role within its ecosystem; its "job"
What is a niche?
An animal that eats plants or other animals and does not make its own food.
What is a consumer?
An organism that uses sunlight to create its food
What is a producer
A group of the same species living in the same place at the same time
What is a population?
3 examples of biotic factors
Plants, animals, fungi, bacteria
The arrows in a food chain and food web represent this
What is the flow of energy?
A group of populations of organisms interacting with each other in a common habitat
What is a community?
Temperature, water, soil, light, and rocks
the flow of energy from a producer to one or more consumers. (ie: linked together by their feeding relationships)
What is a food chain?
In a food web, this is the role of fungi and bacteria
What are decomposers?
Predators do this with/against each other in order to get the food they need
What is compete?
The primary source of carbon that enters the carbon cycle
What is carbon dioxide?
living and nonliving things are parts that make this.
What are ecosystems?
An animal that just eats plants
What is a herbivore?
These are 3 limiting factors for a population
What are food, water, space
The difference between carnivores and scavengers
Both are meat eaters, but scavengers do not hunt
An adaptation that helps an animal blend in with its surroundings
What is camouflage?
The number of individuals of a species an ecosystem can support
What is the carrying capacity?
A community and the physical environment it interacts with (biotic and abiotic factors)
What is an ecosystem?
The decomposer's niche in an ecosystem
What is to break down dead organisms into nutrients for the soil?
A relationship when both benefit each other.
What is mutualism?
A mosquito sucking blood from a person is this type of relationship
What is parasitic (or parasitism)?
An animal that eats meat & plants
What is an omnivore?
A consumer that only eats plants (two possible names)
What is an Herbivore or Primary Producer?
sun + CO2 + H2O --> sugar + O2
What is photosynthesis?
Conditions of the environment that limit the growth of a species
What are limiting factors?
when neither organism benefits or is harmed this is called
commensalism
Create a food chain using the following organisms: Fungi, Fox, Grass, Sunlight, Rabbit
Sunlight --> Grass --> Rabbit --> Fox --> Fungi
The definition or explanation of an Apex Predator
What is an animal that is at the top of its food chain that does not have a natural predator?
The position an organism occupies in a food chain or food web
What is trophic level?
