Which statement
best
describes the way organisms will interact in relation to water in the desert?
Organisms will be a limiting factor.
Desert animals will have high pop density where there is little water.
Organisms will compete for the resource of water.
Water will reach carrying capacity when there are many desert organisms.
2
Maximum number of organisms of a species that an ecosystem can support.
carrying capacity
competition
limiting factor
3
A farmer clears acres of forest to plant corn. How will this affect the carrying capacity of the salamanders?
The corn field will support a higher # of salamanders.
The corn field will support the same # of salamanders.
The corn field will support fewer salamanders.
4
Why are invasive species a problem for native species? (choose 2)
Invasive species interbreed and produce offspring with native species.
Invasive species cause the climate of Pennsylvania to change.
They lower the carrying capacity of the ecosystem for native species.
Invasive species compete with native species for resources.
5
Bluebirds nest in cavities. Nesting boxes are installed in a meadow. How does this affect the population of bluebirds?
The population will decrease because the nesting boxes take up space.
The population will remain the same because the amount of food decreases.
The population will increase because there are more nesting resources.
The population will decrease because the number of predators will increase.
