Interactions
This interaction happens when two organisms compete for the same limited resource.
What is competition?
A body feature or behavior that helps an organism survive.
What is an adaptation?
The gradual change in an ecosystem over time.
What is succession?
The variety of living things in an area.
What is biodiversity?
These are benefits people receive from ecosystems.
What are ecosystem services?
A lion hunting a zebra is an example of...
What is predation?
This interaction occurs when one organism hunts and eats another.
What is predation?
The role an organism plays in its ecosystem.
What is a niche?
This type of succession begins where no soil exists.
What is primary succession?
Healthy ecosystems usually have high or low biodiversity?
What is high biodiversity?
Bees provide this ecosystem service.
What is pollination?
A bee and a flower have this relationship.
What is mutualism?
This relationship benefits both organisms.
What is mutualism?
Long necks help giraffes reach leaves high in trees. This is an example of a(n)...
What is an adaptation?
These are often the first organisms to grow during primary succession.
What are pioneer species?
Human activities like habitat destruction often cause biodiversity to do this.
What is decrease?
Wetlands help clean water. This ecosystem service is called...
What is water purification?
After a volcanic eruption creates new rock with no soil, this type of succession begins.
What is primary succession?
This relationship benefits one organism while harming another.
What is parasitism?
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!)
Lichens are an example of this type of organism.
What are pioneer species?
A species introduced into a new habitat that harms native species is called this.
What is an invasive species?
Give one other ecosystem service besides pollination.
Examples include clean water, oxygen production, climate regulation, food, medicine, soil formation.
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!)
This relationship benefits one organism while the other is neither helped nor harmed.
What is commensalism?
True or False: Two different species can have exactly the same niche in the same ecosystem forever.
False
This type of succession occurs after a wildfire when soil is still present.
What is secondary succession?
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!)
Why are ecosystem services important?
They help support life by providing resources and benefits people and other organisms need.
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.
