This interaction happens when two organisms compete for the same limited resource.

What is competition?

100

A body feature or behavior that helps an organism survive.

What is an adaptation?

100

The gradual change in an ecosystem over time.

What is succession?

100

The variety of living things in an area.

What is biodiversity?

100

These are benefits people receive from ecosystems.

What are ecosystem services?

100

A lion hunting a zebra is an example of...

What is predation?

200

This interaction occurs when one organism hunts and eats another.

What is predation?

200

The role an organism plays in its ecosystem.

What is a niche?

200

This type of succession begins where no soil exists.

What is primary succession?

200

Healthy ecosystems usually have high or low biodiversity?

What is high biodiversity?

200

Bees provide this ecosystem service.

What is pollination?

200

A bee and a flower have this relationship.

What is mutualism?

300

This relationship benefits both organisms.

What is mutualism?

300

Long necks help giraffes reach leaves high in trees. This is an example of a(n)...

What is an adaptation?

300

These are often the first organisms to grow during primary succession.

What are pioneer species?

300

Human activities like habitat destruction often cause biodiversity to do this.

What is decrease?

300

Wetlands help clean water. This ecosystem service is called...

What is water purification?

300

After a volcanic eruption creates new rock with no soil, this type of succession begins.

What is primary succession?

400

This relationship benefits one organism while harming another.

What is parasitism?

400

DAILY DOUBLE!  A niche includes how an organism gets food and these conditions it needs to survive.

What are its living and physical conditions (habitat/resources)? (if you got this right you get DOUBLE the points!)

400

Lichens are an example of this type of organism.

What are pioneer species?

400

A species introduced into a new habitat that harms native species is called this.

What is an invasive species?

400

Give one other ecosystem service besides pollination.

Examples include clean water, oxygen production, climate regulation, food, medicine, soil formation.

400

DAILY DOUBLE: Name the two main types of succession.

What are primary succession and secondary succession? (if you got this right, you get DOUBLE points!)

500

This relationship benefits one organism while the other is neither helped nor harmed.

What is commensalism?

500

True or False: Two different species can have exactly the same niche in the same ecosystem forever.

False

500

This type of succession occurs after a wildfire when soil is still present.

What is secondary succession?

500

DAILY DOUBLE: Name one way people can help protect biodiversity.

Examples: protect habitats, reduce pollution, plant native species, create wildlife preserves, protect endangered species. (If you got this right, you get DOUBLE points!)

500

Why are ecosystem services important?

They help support life by providing resources and benefits people and other organisms need.

500

Explain why biodiversity and ecosystem services are connected.

Healthy ecosystems with high biodiversity provide important ecosystem services such as pollination, clean water, food, oxygen, and habitat. When biodiversity decreases, these services can also be reduced.
