Question

Ground squirrels engage in alarm calls to alert their fellow squirrels that a predator may be present. Silent squirrels may start calling if they hear a call. Over time, calling squirrels may stop calling if the danger has not materialized. With this information, write equations about the rate of change of the two populations of silent and calling squirrels. (Question has to do with population modeling).

I have tried answering this and have worked with a tutor but would like some extra help. Thank you!

Explanation / Answer

Ground squirrels engage in alarm calls to alert their fellow squirrels that a predator may be present. Silent squirrels may start calling if they hear a call. Over time, calling squirrels may stop calling if the danger has not materialized. With this information, write equations about the rate of change of the two populations of silent and caling squirrels. If it helps, draw a flow diagram representing the number of silent and calling ground squirrels over time and label flow rates above each arrow in the diagram.
