Module 1 Quiz

A population that follows a J-curve pattern:

According to Malthus, populations can increase forever. True or false?

What does the T in the IPAT formula stand for?

Refer to the Malthus diagram below:

The point at which the green and blue lines intersect is known as the:

Refer to the growth curve diagram below:

What is the purple line supposed to represent?

What occurs at a Malthusian “point of crisis”?

What occurs in a “Malthusian catastrophe”?

S-curves show the highest rate of growth:

If someone were to say:

“The Earth’s carrying capacity is limited by the availability of fresh water, and the sustainable limit of water use is 3 billion people, so therefore there will be a big population crash in the near future as Earth’s agricultural systems are not sustainable.”

We might say that this is an example of:

According to the SI = P x C/P x I/C formula, if population doubled, does this mean that the sustainability impact is also at least doubled?

Refer to the growth curve diagram below:

After a long amount of time has elapsed, populations following the purple curve:

Refer to the growth curve diagram below:

After a long amount of time has elapsed, populations following the red curve:

This diagram illustrates the important ideas behind the Malthusian model of population. The blue curve represents the total population, and the green line represents the amount of food available.

If the Malthusian theory is accurate, why do the curves in the figure not follow the paths shown?

Human over-population can be described as occurring whenever the population exceeds the local carrying capacity. Over the 20^th and 21^st centuries, it has become unclear how fixed carrying capacities of local human populations are, or even what that capacity might be, as changes in technology have driven record increases in global population. Imagine if the carrying capacity is exponentially related to human population. Which of the following observations would most closely be associated with this relationship?
