The animal that does not walk by moving the two legs on one side together and then the other is the giraffe. Giraffes walk by moving both legs on one side of their body forward at the same time, followed by both legs on the other side.
If a fast moving stream becomes slow moving over time, the changes in plant and animal life might include the colonization of new plant species adapted to slower water flow, an increase in sediment deposition altering the streambed habitat, and a shift in the types of fish and invertebrates that can thrive in the slower-moving water. The slower flow can lead to more nutrient buildup, potentially affecting the overall biodiversity of the ecosystem.
