a living thing

what is organism

100

This is a group of organisms that can mate with each other and produce offspring.

What is a Species

100
Birth and death rates control what?

What is population size.

100

This is an environmental factor that causes a population to stop growing or decrease in size.

Limiting Factor

100

This is when you use your 5 senses.

Observations

200

the parts of a habitat that are, or were once, alive and interact with an organism

Biotic Factor

200

This is all the members of one species living in the same area.

What is a population

200

If the hammerhead shark population decreases, what happens to the sting ray population?

It increases

200

These two resources can be a limiting factor for virtually any population.

Food and Water

200

This causes the change in an experiment. 

Independent Variable

300

The nonliving parts of an organism's habitat

Abiotic Factors

300

This is all the different populations living together in an area.

What is a community

300

When a species moves into a population

immagration
300

The largest population an area can support

Carrying Capacity

300

This is when you use prior knowledge from observations 

Inference

400

Lichen living on a dead tree is an example of what?

Biotic Factor

400

The community of organisms living together interacting with the nonliving environment.

What is an ecosystem

400

When a species leaves a population

emigration

400

These two things can have both immediate and long-term effects on a population, such as natural disasters.

Climate and Weather

400

This is the effect of what you measured

Dependent Variable

Abiotic Factor

500

A group of ducks live together at a pound. What is this an example of?

500

This is the number of individuals in an area of specific size
