According to the ideas of Thomas Malthus, what are the predicted changes to the human population after 2050? A. The population would continue to increase at the same rate, due to constant food supplies. B. The population would increase more rapidly, due to advances in technology. C. Eventually the population would stop increasing or would decrease, due to lack of food and living space. D. Eventually the population would decrease to zero, because of war, famine, or disease.arrow_forward

What do these growth curves look like. Which represents human population growth over the last few thousand years?arrow_forwardSome demographers claim that the total world population has already begun to slow, while others dispute this claim.

State the purpose of the experiment using the question. Explain the background of the experiment and briefly describe the procedure. When explaining the background of the experiment, you are giving a overview of limiting factors. You should include information found in the background of the lab. Include a summary of the steps used to gather data. Describe how each of the limiting factors you studied in the simulation affected population growth and carrying capacity( migration, predation, food, disease, and pollution) include a reason why you think the limiting factor affected the population growth in this way.arrow_forward
