6. Plant Adaptations • Lily Pad – large areas of air tissue in the leaves so they will stay afloat • Most Pond Plants – Air is drawn in through the leaves and is transported to the roots through air tissue

7. Animal Adaptations • Beaver – teeth that always grow so they can easily get tree bark • Mallard Duck – webbed feet so they can swim
