A laboratory experiment followed the growth of a flour beetle (Tribolium sp.) population over time. At first, the population increased dramatically, but later growth slowed and the population size leveled off. While food (the wheat flour in which they live) was abundant, it was noticed that flour beetles resorted to eating their own eggs when densities got high. What can we conclude about cannibalism in this species?

It serves as a density-dependent means of population control.

The concept of ecological footprint is measured in terms of the amount of

Technology has allowed the species to overcome some environmental resistance

Under which of the following conditions would a population grow?

The birth rates exceeds the death rate and there is no immigration or emigration.

A country has a TFR of 1.6 (which is below the replacement rate), yet its population continues to grow. What is one likely explanation for the deviation from the norm.

The net immigration is high enough to overcome TFR.

a particular country has a TFR equal to the replacement level fertility and emigration equal to immigration. Which of the following must be true?

The population MUST be stable

compete intensely

An experiment uses two groups of mice with 20 individuals in each group. Both groups are fed the same amount of water and food every day. They are kept in similar cages in a climate-controlled room. The experimental group is given five doses of a pesticide every day. After two months, the amount of an enzyme in the brains of the mice was measured. Use Passage 1-2. The group of mice not exposed to the pesticide is called the
