Are plants and animals the only beneficiaries of the "natural and beneficial functions" of floodplains? Correct Answer No. People benefit from floodplains through the food they provide, the recreational opportunities they afford, and the scientific knowledge gained in studying them. Floodplains also recharge groundwater supplies and their filtering actions help improve water quality.

What does filling in a floodplain do? Correct Answer Filling reduces the floodplain's ability to store excess water, sending more water downstream and causing floods to rise to higher levels.
