Consider the following scenario:
You are a scientist observing rodents on the Galapagos Islands. You notice that the introduction of new bird of prey has limited the number of rodents.
What term best describes the factor that is limiting the number of rodents the environment can support?

The term that best describes the factor that is limiting the number of rodents the environment can support is "selective pressure", as the introduction of a new predator is putting pressure on the rodent population and limiting their ability to survive and reproduce.
Well, well, well, looks like those rodents are learning the harsh reality of the food chain on the Galapagos Islands. The term that best describes the factor limiting their numbers is "selective pressure." That new bird of prey is putting the heat on those little critters, making it harder for them to survive and reproduce. Tough break for the rodents, but hey, survival of the fittest, am I right?
The term that best describes the factor limiting the number of rodents in this scenario is "selective pressure."
The term that best describes the factor limiting the number of rodents the environment can support in this scenario is "selective pressure."
To determine the answer, we need to understand the concept of selective pressure. Selective pressure refers to any external factor that limits the survival and reproductive success of individuals in a population. In this scenario, the introduction of a new bird of prey is acting as a selective pressure on the rodent population by preying on them. The increase in predation by the bird of prey restricts the number of rodents that can survive and reproduce, thus limiting the population size.
Therefore, the correct term that describes the factor limiting the number of rodents in this scenario is "selective pressure".
