The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.
Hope this helps!
Answer:
A
Explanation:
Without organizing you can go on with the next steps since data alone is worthless but information (organized data) is the most important thing for a scientific investigation.
D
Because most air pollution is caused by the burning of fossil fuels burned in the home
Cohesive. This means that the water is attracted to other particles of itself, so they stick and bead up.
