Question

1. think about it: a limiting factor is any factor that controls the growth of a population. what do you think are some of the limiting factors for the rabbit population? 2. run gizmo: select the description tab. set the simulation speed to fast. select the graph tab. click play, and allow the simulation to run for at least 10 years. (note: you can use the zoom controls on the right to see the whole graph.) a. describe how the rabbit population changed over the course of 10 years. b. what pattern did you see repeated every year? c. how could you explain this pattern?

Explanation:

1. For the limiting - factors question, in nature, factors like food availability, presence of predators, disease, and space can limit the rabbit population. Food is necessary for survival and reproduction, predators hunt rabbits reducing their numbers, diseases can spread quickly among them, and limited space restricts population growth.
2. A. The rabbit population might initially grow rapidly due to ample resources and then stabilize or decline as it approaches the carrying capacity of the environment (the maximum number of individuals the environment can support).
3. B. Seasonal changes can affect the rabbit population. For example, in spring and summer, there is more food available which can lead to population growth, while in winter, food scarcity and harsher conditions might cause a decline.
4. C. The pattern is likely due to seasonal variations in food availability, temperature, and predator - prey dynamics. In warmer months, plants grow more, providing more food for rabbits, and predators may also be more active. In colder months, food becomes scarce and survival becomes more challenging for rabbits.

Answer:

1. Possible limiting factors for the rabbit population include food availability, predators (such as foxes, wolves), diseases (like rabbit hemorrhagic disease), and available living space.
2. A. The rabbit population likely experiences an initial period of rapid growth followed by stabilization or a slight decline as it approaches the environment's carrying capacity.
3. B. Seasonal changes in food availability and weather conditions might cause fluctuations in the population every year. For example, more food in spring and summer could lead to population growth, while winter scarcity could cause a decline.
4. C. The pattern is due to seasonal variations in resources (food and water), temperature (which affects survival and reproduction), and predator - prey interactions. In spring and summer, more food is available and warmer temperatures are favorable for reproduction, leading to population growth. In winter, food is scarce and cold temperatures can increase mortality rates.
