The water hyacinth is an invasive species that can spread extremely fast, blanketing a water surface in a very short period of time. it can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity. this situation demonstrates a. how migratory patterns change in response to alterations in an ecosystem b. the effects of symbiosis c. the effects of local evolution or migration on an ecosystem d. how changes in biodiversity impact an ecosystem

The correct answer is =  how changes in biodiversity impact an ecosystem

Explanation:

Option D is the correct answer.

Water hyacinth is a type of aquatic weed that spreads extremely fast, thus blanketing the water surface in a very short span of time. Though these weeds are rich in nutrients in the form of compost, but at the same time a lot of fish have died due to these weeds, thus impacting in a negative way.
