Most of Earth’s water (97 percent) is salt water in the oceans. Available fresh water, used by humans and other organisms, makes up less than one percent of the water on Earth (6.6 f).
No resources have been tagged as aligned with this standard.
When excess nutrients flow into an aquatic ecosystem, a chain of events may take place which leads to a low dissolved-oxygen level in the water. This is called eutrophication (LS.8 c).
predict the effect of eutrophication on ecosystems, communities, populations, and organisms.
