Answer:
The most probable result of the increasing concentrations of fertilizers in the prime rivers emptying into oceans is eutrophication followed by hypoxia. This will eventually result in less uptake of carbon dioxide and less release of oxygen.
The fertilizers are among the common pollutants, which degrade the quality of water. The fertilizers comprise chemicals, which are good for plants use, however, the excess amounts used in plants get run off and pollute the water bodies.
The fertilizers mainly comprise nutrients like phosphorus and nitrogen. When it rains, these nutrients get carried to the water bodies and results in algal bloom known as eutrophication. This algal bloom utilizes the oxygen in the water, leaving behind no or fewer levels of oxygen that hampers life of aquatic species.
Two different plants, one from the coniferous forests of Canada, and the other from the tropical rain forest of Belize, will look different, have different adaptations, and different way of functioning.
The plant from the coniferous forests of Canada will have thicker bark, leaves that are needle like, harder and thicker. These will be adaptations for the plant to be able to survive in the very cold winters, as the temperatures are way below zero, and there is lot of snow and ice. This plant will also be capable of minimizing its activity for several months, until the conditions are suitable again. The growth of it will be slow, as the vegetative season is short.
The plant from the tropical rain forest of Belize will have wide and thick leaves. It will be high because there is a lot of competition for sunlight. The plant will be able to stop the intake of water through its roots as in certain periods of the year there's just too much water. It will be highly active throughout all of the year, as it is summer summer for the whole year, and there is sufficient precipitation for most of the year, or even when there isn't there's lot of water around. iT will have a very quick growth.
Answer:
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

The disapperance of many species during a relatively short time is known as extinction
