Organisms and Habitats
a living thing
what is organism
This is a group of organisms that can mate with each other and produce offspring.
What is a Species
What is population size.
This is an environmental factor that causes a population to stop growing or decrease in size.
Limiting Factor
This is when you use your 5 senses.
Observations
the parts of a habitat that are, or were once, alive and interact with an organism
Biotic Factor
This is all the members of one species living in the same area.
What is a population
If the hammerhead shark population decreases, what happens to the sting ray population?
It increases
These two resources can be a limiting factor for virtually any population.
Food and Water
This causes the change in an experiment.
Independent Variable
The nonliving parts of an organism's habitat
Abiotic Factors
This is all the different populations living together in an area.
What is a community
When a species moves into a population
The largest population an area can support
Carrying Capacity
This is when you use prior knowledge from observations
Inference
Lichen living on a dead tree is an example of what?
Biotic Factor
The community of organisms living together interacting with the nonliving environment.
What is an ecosystem
When a species leaves a population
emigration
These two things can have both immediate and long-term effects on a population, such as natural disasters.
Climate and Weather
This is the effect of what you measured
Dependent Variable
The air we breathe is an example of what?
Abiotic Factor
A group of ducks live together at a pound. What is this an example of?
What is a population.
This is the number of individuals in an area of specific size
Population density
When individual organisms compete for where to live or raise young, the limiting factor is what two things?
Space and Shelter
Put the following in order from smallest to largest: community, ecosystem, population, organism
