Describe three density-dependent factors that prevent populations from growing indefinitely. For full credit, you must fully explain how the factor is density-dependent. Of these factors, which do you feel will most limit the growth of the human world population? Explain.
density-dependent factors that prevent populations from growing indefinitely
in nature the making limiting factors that affect population size is the availability of food, spacer or shelter besides these there are other density-dependent factors that prevent populations from growing indefinitely: competition, predation, parasitism, and disease. These factors become noticeable when the population reaches and exceed the limit.
Of all these density-dependent factors, the one that I think is likely to limit human population growth is waste accumulation. Human population has shown exponential growth and unchecked population growth will bring environmental catastrophe. As the population increased, there is a tremendous increase in the accumulation of harmful waste. As the health of our environment deteriorates, it is likely to cause a decline in the human population, causing the death of individuals due to decrease in potable water, fertile land, forests, etc.

Given this bird population growth data, answer the followign questions: 1) Explain why you think the population grew in the pattern it did 2) Model the population as closely as possible using the logistic equation. Lowever to do so, you'll need to predict the intrinsic rate of increase and carrying capacity. Estimate these vales as must as possible. Report the estimated R and K and graph 1) the populations (both modeled and real on the same graph) against time, 2)...

In your own words, describe the ways in which electroacoustic instruments gained their own identity apart from their acoustic ancestors. 3. Almost immediately, prerecorded music (as opposed to living concerts) began playing on the early airwaves. How do you think this affected how the world would expect music to be delivered from now on? 4.List the examples we discussed that demonstrate the changing role of...
What steps do you take to limit growth of microbes in your home? Explain thoroughly. Explain thoroughly how antimicrobial drug resistance develops and explain some steps that can be taken to prevent it from happening. Explain what is meant by a BSL-4 lab. Would you work in one? Why or why not? You are infected with a bacterial disease. Your sister had this same illness last week, and took a full cycle of antibiotics. She quickly became better. You started...
