Describe the difference between a density-independent limiting factor and a density-dependent limiting factor.
Density-dependent limiting factors affects small/large/clumped/spread-out populations differently.
Identify 3 examples of a density-dependent limiting factor.
Competition for mates
Competition for food
Competition for space
Disease
Predation
Describe how and why the moose population changes in response to the size of the wolf population.
As the wolf population increases, so does predation on the moose, so the moose population decreases.
What is the carrying capacity of the wolf population?
25 - 30
Which community is more likely to survive a disturbance?
Community 1 - more biodiversity due to more species evenness
Which community has more species abundance of elephants?
Community 1
Which community has more species abundance of giraffes?
Community 2
Which community has higher species richness?
Neither - they both have 6 species, so equal richness

What type of succession will take place if a volcano erupts?
Primary
What type of succession will take place if there is a forest fire?
Secondary
What will happen to the shrew population if there is an increase in grasshoppers?
The shrew population will also increase due to more food.
What will happen to the grass population if there is an increase in grasshoppers?
The grass population will decrease due to increased predation.
What will happen to the deer population if there is an increase in grasshoppers?
The deer population will decrease due to less food. (Also acceptable: the deer population will stay the same but begin to eat more trees)
How much rain fell in June?
About 10 mm
What was the average temperature in October?
About -10 C

Otters eat sea urchins and live near surface of the water. Their ecosystem role and habitat is also called their _______.
niche
Name the 3 types of population distributions.
Clumped
Random
Evenly spaced/Uniform
Elephants are usually found in herds around watering holes. What type of distribution would they have?
Clumped
Maple trees disperse their seeds by the wind. Where the seeds land, a new tree may grow. What type of population distribution would maple trees have?
Random
What is an example of an ecosystem service provided by a coral reef?
Provides recreation opportunities
Provides fish for food AND for the aquarium trade

The Margay, a species of wildcat, generally is uncommon to rare throughout their range, and only in very few areas are they relatively common. Generally population densities are between 1-5 individuals per 100 km². Margays are solitary except for a mother with kittens. Males are migratory and can fight other males for access to females. Males frequently die in the process. A single kitten, (rarely two), is born once a year. The young are darker than the adults, and have uniformly dark spots and dark grey paws.
What is the population density of the margay?
1-5 per 100 km²
