Step 1: Evaluate the claim. The assertion, "Insects are vital pollinators for numerous flowering plants," is accurate as many plants depend on insects for pollen transfer, a critical component for reproduction and seed development.
Step 2: Evaluate the justification. The justification details how insects visit flowers for sustenance (nectar or pollen). This interaction leads to pollen transfer between flowers, facilitating cross-pollination. This explanation directly substantiates the claim.
Step 3: Confirm the relationship between the claim and justification. The justification not only supports the claim but also provides the scientific foundation for the statement. Therefore, both the claim and the justification are valid, and the justification accurately explains the claim.
