Take a full mock →Q1 · Organisms and Populations (Class 12) · MEDIUM
A population growing in a habitat with unlimited resources shows exponential growth described by the equation dN/dt = rN. If a bacterial population has an intrinsic rate of natural increase (r) of 0.5 per hour and the initial population size (N0) is 100, what will be the population size after 4 hours?
Q2 · Organisms and Populations (Class 12) · EASY
Which of the following population interactions is represented by the notation (+, -), where the first sign indicates the effect on species A and the second sign indicates the effect on species B?
Q3 · Organisms and Populations (Class 12) · HARD
A population of deer in a forest shows logistic growth according to the equation dN/dt = rN((K-N)/K). If the carrying capacity (K) is 1000, intrinsic rate of increase (r) is 0.2 per year, and current population (N) is 500, at what population size will the population growth rate (dN/dt) be maximum?
