Certainly! Here's a transcription suitable for an educational website:---**Rabbit Population in a Specific Ecosystem***Overview:*The graph titled "Rabbit Population in a Specific Ecosystem" displays the growth of a rabbit population over time in a natural habitat. *Graph Details:*- **Y-Axis (Vertical):** Represents the "Population Size" of rabbits.- **X-Axis (Horizontal):** Represents "Time."- **Curve A:** The graph shows an initial increase in the rabbit population, followed by fluctuations around a relatively stable level.*Key Observations:*- The population initially grows rapidly, indicating a period of favorable conditions or low predation.- After reaching a certain population size, the graph shows oscillations, suggesting environmental checks such as predation, competition, or limited resources affecting population stability.*Questions for Consideration:*7. Which environmental factor could have caused the change indicated by curve A? - A. Increased predation by herbivores---This transcription can help users understand the dynamics of rabbit population growth and the possible ecological factors influencing it. ## Biology Assessment: Population Dynamics and Honeybee Decline### Multiple Choice Question:**13. Which of the following statements is correct?**A. Population size of predators increases when their prey’s population is low. B. Competition for resources is density-independent when food is plentiful. C. Disease is density-dependent because spreading occurs more easily when a population is closer together. D. A change in average temperature is a density-dependent factor because fewer organisms can acclimate to variations in temperature. ### Short Answer Questions:**Base your answers to questions 14–16 on the information below and on your knowledge of biology.***...Unless actions are taken to slow the decline of domesticated honeybees and augment [increase] their populations with wild bees, many fruits and vegetables may disappear from the food supply, said Claire Kremen, a conservation biologist at Princeton University in New Jersey...**The honeybee decline, which is affecting domesticated and wild bee populations around the world, is mostly the result of diseases spread as a result of mites and other parasites as well as the spraying of crops with pesticides, scientists say...**Source: "Bee Declines May Spell End of Some Fruits, Vegetables".*

The number of people in a population will fluctuate owing to natural and human influences. Natural…

3. In 1940 there were 12 whooping cranes in the population. In 1945, five years after hunting whooping cranes was made illegal, ecologists calculated the whooping crane population growth rate (X) at 1.2 and estimated the population size to be 30 individuals. Using the population growth rate calculated from 1940-1945, what would be the estimated population size for whooping cranes 20 years into the future (1965)?
