If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.arrow_forwardA population of grey squirrels started with one pair and grows logistically with annual r = 1 and K = 42.

A biologist for Mosaic fertilizer company catches 26 Florida scrub jays as part of their monthly environmental monitoring. Each bird is given a band. The next month, they catch 32 birds. 13 of the birds have bands.
