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

Correct D). How changes in biodiversity impact an ecosystem

The Water Hyacinth is an unwanted plant and is considered a nuisance plant as it causes a physical, ecological and economic problem. It affects the growth of the aquatic ecosystem.

It forms a thick layer on the water surface and prevents the photosynthesis, it is also responsible to cause the decreased level of oxygen in the water and affect the lives of other organism living in the water.

It clearly shows that how the effect of local evolution on the ecosystem and how the changes in the biodiversity impact an ecosystem.  

The correct answer is D. How changes in biodiversity impacts an ecosystem.

Water hyacinth is termed as a plant which is free-floating aquatic perennial.

Water hyacinth rises above surface of water.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
