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 .

how changes in biodiversity impact an ecosystem

Explanation:

Water hyacinth is an invasive special that is introduced to an environment. It spread rapidly and causes enough damage to bother human,economy and environment.

Hyacinth pollutes the water causing a decrease in oxygen level and other nutrients like passport and nitrogen and it lead to high concentration of heavy metals and contaminant.

It can blankets the ocean causing a decrease in photosynthesis, boat trafficking, swimming and movement of organism in water bodies. It demostrates how changes in biodiversity impact an ecosystem.

a physical change is being made.
