Misconception #1
If a populations growth rate is in decline, than the absolute number of people within that population cannot increase
False:
As long as the rate of growth is not in the negatives, then the worlds population will continue to increase. If the rate of growth decreased from 5% to 4%, then there would still be a net increase in the Earth’s absolute population.

Misconception #2
“r” in the growth equation must be greater than 1.0 to produce exponential growth. (“r” refers to growth rate)
False:
As long as “r” is not in the negatives, then there will be exponential growth.

Misconception #3
All density-dependent factors are biotic and all density-independent factors are abiotic.
False:
Density dependent factors can include natural resources (ie. fruits, water), density independent factors can include human intervention
(ie. pesticide use)

Misconception #4
Developing countries must go through the same processes, steps, or trends that developed countries have gone through (as per the demographic transition model).
False:
Developing countries are able to essentially “leapfrog” over certain developmental stages when going through the demographic transition model.

Misconception #5
Demographers can more often than not, accurately predict population growth based on collected data. (i.e. the world will exceed 10 billion people by 2100)
False:
They can use “medium variant” projection; (10 million) it also put out a “high variant”projection (exceeding 15 billion) and a “low variant” (6.2 billion, lower than the world’s population today).

Misconception #6
Symbiosis refers to a relationship wherin both of the species benefit from each other.
False:
Often students will think that symbiosis results in both species benefitting. Both species benefiting from a relationship is known as mutualism.
