Final answer:
Inland wetlands act as sponges by storing excess water and preventing erosion. They also provide other ecosystem services such as supporting high biodiversity and filtering pollution.
Step-by-step explanation:
Inland wetlands act as sponges by storing excess water from floods and slowing down runoff to prevent erosion. They also remove excess nutrients from runoff before it enters rivers or lakes, helping to maintain water quality. In addition to these sponge-like functions, inland wetlands provide other ecosystem services such as providing a unique habitat for certain plants, supporting high biodiversity, and acting as a filter for pollution. These services contribute to the overall health and functionality of the ecosystem.
