Final answer:
Flood plains have natural and beneficial functions that benefit not only plants and animals but also the environment as a whole.
Step-by-step explanation:
Plants and animals are not the only beneficiaries of the natural and beneficial functions of flood plains. Flood plains play a crucial role in filtering water, protecting coastal lands from storms and floods, and providing habitats for many species. They also help to slow down runoff, prevent erosion, and remove excess nutrients from runoff. Moreover, flood plains can support a high biodiversity, providing a unique habitat for certain communities of plants that depend on them to survive.
