Chapter 40 review

All of the following are density-dependent factors that limit animal populations EXCEPT.

• weather
• predation
• food competition
• birthrate

Refer to the diagram of the survivorship curve.
Which curve best describes an organism that invests a lot of energy in parenting?

• A
• B
• C
• this is not a survivorship curve

A species described as r-strategist would definitely NOT have which of the following characteristics?

• clumped population pattern
• much parenting
• many offspring
• random population pattern

Which letter shows the the exponential growth of a population?

• A
• B
• C
• D

The maximum population size for a species based on the environmental factors is called

• ecological footprint
• carrying capacity 
• population growth
• environmental capacity

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

• A parasite
• A natural disaster
• A decrease in prey
• A food shortage

__________ growth shows growth of a population under environmental constraints (carrying capacity-K) that sets a maximum population size 

• logistic
• exponential
• niche
• uniform

________ grow slowly over time, cares for its young over a long period of time and is usually near the carrying capacity of its ecosystem.

• K-strategists
• R-strategists
• Uniform strategists
• environmentalists

These types of organisms which multiply rapidly in numbers 

• R-strategists
• K-strategists
• predators
• mutualists

J-Shaped curves

• show a decline after an increase
• display populations that have reached carrying capacity
• represent exponential growth
• does not depend on the numbe rof resources
