Part B Please!!
Scenario The population of fish in a fishery has a growth rate that is proportional to its size when the population is small. However, the fishery has a fixed capacity and the growth rate will be negative if the population exceeds that capacity. A. Formulate a differential equation for the population of fish described in the scenario, defining all parameters and variables. 1. Explain why the differential equation models both condition in the scenario. t time a...

1. Single Species Growth Consider a single population where the per capita birth rate declines as the population size grows. Let N(t) be the population size at time t. Consider the following assumptions: (A1) The environment in which the species lives (including the climate, other species and the availability of resources like food, etc.) remains constant. (A2) The per capita birth rate is for some b>0. (A3) The per capita death rate is a constant d > 0. Note: This...

(1 point) Any population, P, for which we can ignore immigration, satisfies dP Birth rate – Death rate. dt For organisms which need a partner for reproduction but rely on a chance encounter for meeting a mate, the birth rate is proportional to the square of the population. Thus, the population of such a type of organism satisfies a differential equation of the form dP аP? — ЬР with a, b > 0. dt This problem investigates the solutions to...
