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.
The answer is C, because if something contagious we’re to threaten the population of the species then not having any variant means they’re all the same and it would kill them all and cause them to go extinct
We need carrier proteins for steroid hormones because they help in the transportation from the cell they were released from to their target cell. let me know if you have any further questions :)
