Accepted Answer

Hi, everyone. Welcome. Let's take a look at our next question. Which of the following is a direct consequence of the overabundance of nutrients in an aquatic ecosystem. A acidification. B, rapid growth of invasive species. C genetic mutation or D eutrophication. Well, when we have an overabundance of nutrients in an aquatic ecosystem, usually due to, for instance, the runoff of waste from agricultural areas including fertilizer, causing an overabundance of nutrients like nitrogen and phosphorus. You end up with the phenomenon of choice d eutrophication and this is a rapid overgrowth of algae and aquatic plants, particularly on the surface of the water stimulated by all those nutrients. You can have the phenomenon of an algal bloom. So you just have this just burst in population covers the surface of the water and then you end up as it uses up all those nutrients and sort of out competes itself, it has this sort of massive die off and decay. And when that happens, it begins to use up the oxygen in that aquatic environment leading to a condition of hypoxia or anoxia. So, low oxygen in the water, which can lead to the death of the animals that live in that wa aquatic environment. When we look at our other answer choices to understand why they're not correct towards a acidification would be a rise in the acidity of an aquatic environment. Usually referring to the ocean. This is not a direct consequence of the overabundance of nutrients acidification rather is a direct consequence of the rise of carbon dioxide levels in the atmosphere. This results in an increased amount of carbon dioxide being dissolved in the oceans which causes them to become more acidic. So to say, is not correct as this is not a direct result of the over abundance of nutrients. T was b the rapid growth of invasive species. Well, if the invasive species in question happened to be in a plant, you might have this, but in general, the rapid growth of invasive species would be caused when you have an invasive species introduced into the environment. It has no natural predators or no natural competition. And of course, when that is in the case, it can grow out of control without any checks on that population. So choice b again, not the consequence of over abundance of nutrients and to see genetic mutation, um it would not be a direct cause of the overabundance of nutrients. What you would look to is the prevalence of carcinogens in the environment. So not the answer we're looking for. So again, we are looking for the direct consequence of the overabundance of nutrients in an aquatic ecosystem which is choice D eutrophication. See you in the next video.
