Ecology and Carbon Cycle

The movement of a single caribou into a herd is an example of

• population
• immigration
• emigration
• predation

The way in which individuals of a population are spread out is called

• population density
• survivorship
• population dispersion
• logistic curve

Which of the following is a density-independent limiting factor?

• natural disaster
• predation
• disease
• parasitism

What pattern of growth will a population with limited resources show?

• density-dependent
• exponential 
• logistic
• logical 

What type of population growth is shown in the graph?  

• logistic growth
• logical growth
• exponential growth
• density-dependent growth

What 2 factors decrease population size?

• Immigration, Births
• Emigration, Births
• Emigration, Deaths
• Immigration, Deaths

A population is...

• A group of one species in one area
• Multiple species that live in one area
• All of the living and nonliving things in an area
• None of these

Which of the following populations is most likely to go extinct?

• a very small population in an unstable environment

• a moderate-sized population of r strategists

• a large population with lots of genetic variability

• all would be equally likely to go extinct

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

Carrying Capacity is

• the capacity of what one person can carry per day 
• how many animals you have in your daily bag limit at the end of the year
• wildebeest at a watering hole with zebras
• the maximum number of individuals that the environment can support
