Final answer:
The loss of wetlands affects both biotic and abiotic elements of an ecosystem, with restoration often requiring removal of invasive species, sediment dredging, planting native plants, and building silt barriers.
Step-by-step explanation:
Loss of wetlands has a significant impact on both the biotic and abiotic components of ecosystems. Wetlands serve as critical habitats, offering resources such as water, fish, and waterfowl, and play a role in filtering pollution and acting as natural barriers against floods.
The decline in wetland areas can be attributed to factors such as silt accumulation and the spread of invasive species, which disrupt water flow and the delicate ecological balance. To address wetland restoration, multiple actions may be needed, but often, initial steps include removing invasive species, dredging to remove sediment, planting native vegetation, and constructing barriers to prevent further silt accumulation.
