How can the changes in water
resources affect an ecosystem

Explanation:

The consequences can be seen in reduced spring yields, diminished river flow, poorer water quality, damage to natural habitats such as wetlands, and the gradual sinking of land, known as subsidence.

The main function of water is to propel plant growth; provide a permanent dwelling for species that live within it, or provide a temporary home or breeding ground for multiple amphibians, insects and other water-birthed organisms; and to provide the nutrients and minerals necessary to sustain physical life.

Examples of environmental impacts include: Losses or destruction of fish and wildlife habitat. Lack of food and drinking water for wild animals. Increase in disease in wild animals, because of reduced food and water supplies.
