African Lions: Modeling Populations Activity | Instant Homework Solutions

READ EVERYTHING BELOW BEFORE GOING TO THE SIMULATION Go to the website: to an external site. and follow the instructions. As you read, answer the questions that are on each screen (you can see the questions below too), record your answers on the following:  Answer Sheet is the PDF Which of the following is an example of ecology? Which of the following questions interests you the most? From 1960-1963, the population of lions in the crater decreased. Which of the following is most likely to have been true from 1960-1963? What would have to be true, on average, from 1952-1956? What do you predict will happen to the lion population after 1963? a. Explain. b. Draw your prediction on the graph to the right, starting from 1964. (Take a screenshot of your drawing and insert into your document). Can you predict what the growth curve might look like over 12 hours? Draw your prediction on the graph to the right. (Take a screenshot of your drawing and insert into your document). In which hour are the bacteria growing the fastest? Pick a point in that hour. Look at the lion population from 1963 to 1975. Do you think this rate of growth will continue to increase? Who or why not? Using the picture to the right to get started, brainstorm a list of at least three limiting factors that might affect the lion population in the crate. Click a point on the graph where you think competition for space was low for the bacteria Use the graph to draw your prediction about the lion population from 1980 to 2012. (Take a screenshot of your drawing and insert into your document). Draw a line to estimate the carrying capacity of the petri dish. (Take a screenshot of your drawing and insert into your document). Draw a line to estimate the average carrying capacity of the environment prior to the disease outbreak (affecting lions) that took place in the early 1960s. (Take a screenshot of your drawing and insert into your document). Using what you now know about carrying capacity, redraw a new prediction of the lion population after 1963. (Take a screenshot of your drawing and insert into your document). Compare your prediction to the real data. What do you notice? If there are differences, can you suggest some causes? Which of the following is a density-independent limiting factor that could cause fluctuations in the carrying capacity between 1995 and today? Given the shape of these graphs, do you think Earth’s population will reach carrying capacity? What might be some limiting factors? What do you think will happen if we do reach carrying capacity? Choose one of the following to answer: What factors can influence how populations change over time? What is the difference between exponential and logistic growth? How can we apply population models to real world data? What inferences can we make about the human population?
