Textbook Question
Chapter 53, Problem 21TYK
An ecological footprint is an estimate of
- a. the
carrying capacity of a nation. - b. the number of offspring an adult produces and the resulting demand on resources.
- c. the land and water area needed per person to meet the current demand on resources.
- d. how much energy is used to produce food for a vegetarian versus a meat eater.

Students have asked these similar questions
A population’s ecological footprint is measured in terms of:
a
how many resources the population uses.
b
how much land area is needed to support its lifestyle.
c
the amount of waste/pollution it produces.
d
the number of people who live there.
b. The graph below shows the population size changes of two animals
over an 90-year span. Study the graph and then answer the
questions which follow:

b.
i. What was the carrying capacity of the habitat for the predator
population in 1855?
ii. Compare the carrying capacities for both populations and
explain why there is a difference.
c. Suggest one factor, other than the presence of prey, that may afieot
the size of the predator population.
d. The graph shows a predator-prey relationship that is based th a
temperate climate. Identify one such relationship that exists:

ii. In a Barbadian garden:

The carrying capacity (K) is the maximum population size that can be supported or sustained by a given environment. Which of the following statements about the carrying capacity is NOT true?
Select one:
a. We can think of K as some "average" value that a given environment can support.
b. Environmental fluctuations cause the carrying capacity to fluctuate over time.
c. Once a population reaches its carrying capacity, the size of the population remains constant.
d. When a population overshoots K, individuals die due to lack of resources.
