Question

1. how could you increase the carrying capacity of deer in a national park? (check 2 answers)

a. y/n not allowing hunting
b. y/n by increasing the meadow (grass) land
c. y/n by adding wolves
d. y/n by decreasing the size of the national park

1. what are examples of limiting factors? (check all that apply)

a. y/n predation
b. y/n unusual weather
c. y/n diseases/parasitism
d. y/n human activities
e. y/n an abundance of food - lots of food

Explanation:

• Question 6:
• Carrying capacity refers to the maximum number of individuals of a species that an environment can support.
• Option A: Not allowing hunting would mean fewer deer are removed from the population. This can lead to an increase in the deer population as more individuals survive.
• Option B: Increasing the meadow (grass) land provides more food for the deer. With more food available, more deer can be supported, thus increasing the carrying capacity.
• Option C: Adding wolves would introduce a predator. Predators reduce the population of their prey (deer in this case), so this would decrease the deer population and not increase the carrying capacity.
• Option D: Decreasing the size of the national park reduces the available habitat for the deer. Less habitat means fewer resources (space, food etc.) and thus a lower carrying capacity.
• Question 7:
• Option A: Predation is a limiting factor. When predators hunt and kill prey, it limits the growth of the prey population.
• Option B: Unusual weather (e.g., extreme cold, drought) can affect the survival and reproduction of organisms. For example, a drought can reduce the availability of water and food, limiting the population size.
• Option C: Diseases and parasitism can kill or weaken organisms. This reduces the number of healthy individuals in a population, acting as a limiting factor.
• Option D: Human activities (e.g., deforestation, pollution) can destroy habitats, introduce pollutants that harm organisms, or over - harvest species. All these can limit population growth.
• Option E: An abundance of food is not a limiting factor. Instead, it can support a larger population size.

Answer:

• Question 6: A. Y, B. Y
• Question 7: A. Y, B. Y, C. Y, D. Y
