1 pts Question 8 Which of the following best describes the technique Gause used to study competition? Manipulate the resources available to each species and measure their fitness. Determine the niche for each species and compare niche breadth. Determine the niche for each species and manipulate resource availability. Compare the fitness of each species when the two are grown separately versus when grown together. None of the above.

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...
