The definition of biodiversity is _____________________.
What is the variety of different organisms living in a certain area?
100

The organism that a parasite lives in or on in a parasitism interaction.

What is a host?

200
The community of organisms that live in a particular area, along with their nonliving surroundings. This includes abiotic and biotic factors.
What is an ecosystem?
200

What is carrying capacity?

The maximum number of individuals that the ecosystem can support

200

What happens when a new predator is introduced?

Increased competition between predators (interference competition) for prey

200

The term given to a species that plays a very important role in an ecosystem. The ecosystem would fall apart quickly if this species dissappeared.

 keystone species

200
An organism that is killed and eaten by another organism.
What is prey?
300
A relationship between two species in which one species benefits and the other is neither helped nor harmed.
What is commensalism?
300

provide an example of a factor that does NOT decrease carrying capacity

ex) Increased available resources

300

What usually happens when resources decrease?

Increased competition

Increased death of individuals

Decreased Birth Rate

300
The two reasons biodiversity is important.
What are for economic reasons, medical reasons, scientific reasons, enviromental reasons?
300
A carnivore that feeds on the bodies of dead organisms.
What is a scavenger?

How would the introduction of a new disease that targets rabbits affect the carrying capacity of the rabbits and the canadian lynx population?

- decrease in the rabbit population due to the disease lowering survival and reproduction will result in a decrease in the lynx population due to less food availability.

In the preferred zone

500

What is the difference between intraspecific and Interspecific competition?

Intraspecific- competition between two of the same species

Interspecific between two or more different species

500

How do disturbances affect biodiversity?

Disturbances often cause changes in biodiversity.

500
