naturalist
Describe how a food pyramid is organized.
Organisms in a ranking order according to dominance in a food web
A water habitat in which water tends to move for long periods of time is called a:
lotic habitats
Explain how a high degree of specialization in a species makes it more vulnerable to becoming extinct.
If an animal is too specialized, they will not be able to adapt to changes in their environment, causing them to be vulnerable to extinction.

balanced

rabbit

ecologist
Describe the annual hydrologic cycle of a typical vernal pool. How does this cycle impact the plants and animals that rely on these habitats?
Some living organisms depend on the dry season to breed, some depend on the wet season, less competition in the different seasons.

alien species
What impacts do modern farming methods have on ecosystems in North America?
Nearly all land suitable for crop production is used for growing crops. Destroyed habitats, but may provide food and some shelter for other biota.
Secondary succession occurs on which type of landscape?
