Answer:
Carbohydrate (monosaccharide)
Explanation:
Carbohydrates are one of the four biological molecules in nature. Carbohydrates are structurally composed of carbon, hydrogen and oxygen elements. However, these elements (C,H,O) are present in each carbohydrate in the ratio 1:2:1 respectively.
As stated in this question, glucose is an organic molecule made up of carbon, hydrogen and oxygen in the 1:2:1 proportion, hence, it is a CARBOHYDRATE. Since glucose possess one sugar component, it is classified as a MONOSACCHARIDE with a chemical formula C6H12O6.

Answer: By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
Climate effects and human impacts, that is, nutrient enrichment, simultaneously drive spatial biodiversity patterns. However, there is little consensus about their independent effects on biodiversity. ... Species turnover rates caused by nutrients do not increase toward higher temperatures
