Question

activity c (continued from previous page)

1. investigate: deselect harsh winter. select cold spring. click play, and observe the how the population changes over a period of five years. paste a snapshot of the graph in your document and label the graph “cold spring.”

a. how does the cold spring graph differ from the normal weather graph?
b. what do you think most likely caused the differences seen in the two graphs?

1. predict: how do you think a period of hot summers will affect the rabbit population?

Explanation:

A. In a cold - spring scenario, the population graph might show slower growth or even a decline compared to the normal - weather graph. This is because cold spring conditions can affect food availability, reproduction rates, and survival of the organisms in the population. For example, plants might grow more slowly, reducing the food supply for herbivores like rabbits.
B. The differences are likely caused by the impact of cold spring on the ecosystem. Cold temperatures can delay the growth of plants, which are the base of the food chain. This can lead to less food for primary consumers, and in turn, affect higher - level consumers. Also, cold conditions can increase the energy requirements of animals to maintain body temperature, putting additional stress on the population.
For the prediction about hot summers: Hot summers could have multiple effects on the rabbit population. If it leads to drought conditions, it could reduce the availability of water and food, causing the population to decline. However, if the hot summers do not cause extreme water or food shortages and instead increase the growth of certain plants that rabbits eat, the population might increase.

Answer:

A. The cold - spring graph may show slower growth or decline due to reduced food availability and harsher conditions.
B. Cold spring impacts the ecosystem, especially plant growth and animal energy requirements.

1. Hot summers could either decrease (if there are water/food shortages) or increase (if plant growth beneficial to rabbits is enhanced) the rabbit population.
