Problem 2 - Biology: The Dynamic Science

Question

Which of the following is usually the first step in the disruption of a natural habitat by humans? a. establishment of small villages b. planting of crops c. building of a road d. invasion by exotic species e. overexploitation of resources

Step-by-Step Solution

Answer

c. building of a road

Step 1: Understand the Options

Go through each option in the multiple-choice question and understand what they mean to the context of habitat disruption. Options are: a. Establishment of small villages, b. Planting of crops, c. Building of a road, d. Invasion by exotic species, e. Overexploitation of resources.

Step 2: Identify the Initial Step in Human Disruption

Consider the sequence in which human activities typically occur in the disruption of a natural habit: Before establishment of settlements or agriculture, there usually needs to be some form of access into the area. Then, humans can establish small villages or plant crops, which may lead to overexploitation and the introduction of exotic species.

Step 3: Pick the Correct Answer

Based on the logic from Step 2, it can be inferred that the building of a road usually precedes the other listed activities, as it facilitates access into the previously undisturbed area.
