Suppose an experiment was conducted where all of the rabbits were removed from a meadow. Which of the following results is least
likely to be observed? (1) The predator population, such as hawks, would decrease.
(2) The grasses and shrubs would grow taller and fuller.
(3) Flea and tick populations would increase.
(4) Other small herbivore populations would increase.
In a given ecosystem rabbits serve as prey for several predators. The growth of predator population is depended on the population of rabbits. The higher the population of prey, the higher is the population of predator.
Thus, if the population of rabbit is decreasing, then the population of predator such as hawks will decrease.
Since the rabbits eat grasses and shrubs, thus in their absence the productivity of grasses and shrubs will also increase.
Preventing illnesses, more quickly diagnose, control diseases, treat diseases with fewer side effects, and create better medical aids such as more compatible prosthetics.
I think the correct answer from the choices listed above is 0. The kinetic energy after the perfectly inelastic collision would be zero Joules. A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. Hope this answers the question.
