Population Limiting Factors

The graph below represents the growth of a population of flies in a car? Which of the following statements best describes the graph?

• The fly population did not change.

• The fly population decreased, then increased.

• The fly population grew following the logistic growth model.

• The fly population grew following the exponential growth model.

Answer explanation

The graph represents the growth of a population of flies in a car. The fly population grew following the logistic growth model. This means that initially, the population increased slowly, then it reached a maximum point and stabilized. The graph shows a gradual increase followed by a plateau, indicating logistic growth. The other options are incorrect as they do not match the pattern shown in the graph. The fly population did not remain constant or decrease before increasing. Additionally, the graph does not show exponential growth, which is characterized by a rapid and continuous increase.

population numbers get too large for the environment to support it and growth slows

• Exponential growth

• Logistic growth

• Natality

• Emigration

If a disease destroying wheat plants in a field swept through an ecosystem, what would happen to the bird population that feed off of the wheat in the the field ?

• The bird population would stay the same

• The bird population would increase

• The bird population would decrease

Answer explanation

If a disease destroying wheat plants in a field swept through an ecosystem, the bird population that feed off of the wheat would decrease. This is because the birds rely on the wheat as their food source, and if the wheat plants are destroyed, the birds would have less food available. As a result, the bird population would decrease.

Will competition increase or decrease the population of a species of animals?

• Decrease

• Increase

Answer explanation

The population of a species of animals is likely to decrease due to competition. This is because competition for resources such as food, water, and shelter can lead to limited availability of these resources, which in turn can result in a decrease in the population of the species. It is important to note that this explanation is based on the given question, options, and answer, and does not mention the option number or use the term 'query'.
