What type of succession occurs on newly exposed rock?
Primary succession.
100
Name one limiting factor that restrains population growth.
Space, food, water, predation, or competition
100
What type of symbiotic relationship benefits both organisms?
Mutualism.

Where are the Aleutian Islands Located?

Succession that occurs in an area where the community was destroyed, but the soil is still intact.
secondary succession

What is exponential growth?
A population that grows rapidly, often represented by a J-shaped curve.

What is Population Ecology?
The study of species populations and how they interact with their environment
300
Name the pioneer species in primary succession.
Lichen, mosses, bacteria, fungi, and grasses.
300
Draw a logistic growth graph and include all the labels it needs.
s-curve with carrying capacity
300
What does population density refer to?
number of individuals per unit area
300
How did human activity contribute to the decline in sea otter populations, and what measures have been taken to reverse this?
Human activities like hunting for fur and pollution have reduced sea otter populations. Conservation efforts, including legal protections and habitat restoration, have been initiated to reverse this

What term explains water sources such as ponds or lakes filling with sediment?

Describe the effects we see in the Aleutian Islands because of current otter populations
high sea urchin populations, low kelp, ecosystem starting to collapse, etc.
500
Why does secondary succession occur faster than primary succession?
Secondary succession is faster because soil already exists.

What term explains how the disappearance of a single species, such as the sea otter, can destabilize an entire ecosystem?
Keystone Species
