Question

a student is investigating the population size of rabbits in a woodland ecosystem. she researches the known population of rabbits over 125 years and creates a graph representing the rabbit population with a solid line and the ecosystems carrying capacity with a dotted line.based on the information in the graph, what conclusion can the student draw about the time period between 1820 and 1860?a. the rabbit population had few limiting factors and the ecosystem was beyond its carrying capacityb. the rabbit population had many limiting factors and the ecosystem was beyond its carrying capacityc. the rabbit population had few limiting factors and the ecosystem had not yet reached its carrying capacityd. the rabbit population had many limiting factors and the ecosystem had not yet reached its carrying capacity

Explanation:

• Carrying capacity concept: Carrying capacity is the maximum number of a species that an ecosystem can sustain. A dashed line in the graph likely represents this.
• Population growth before 1880: The rabbit population shows a rapid - increasing (exponential - like) trend. In an exponential growth phase, limiting factors (such as lack of food, space, or presence of predators) are minimal. When an ecosystem has not reached its carrying capacity, populations can grow more freely.

Answer:

C. The rabbit population had few limiting factors and the ecosystem had not yet reached its carrying capacity.
