Question

diving ducks take off by:
○ running across the water
○ swimming underwater
○ flying from trees
○ jumping straight up

Explanation:

Diving ducks have adaptations for taking off. They typically take off by jumping straight up (using their strong legs to propel themselves vertically from the water surface) rather than running across water (more common in some surface - feeding ducks), swimming underwater (for diving, not take - off), or flying from trees (they are water - based for take - off in most cases).

Answer:

D. Jumping straight up
