Solar energy<span> drives the </span>cycle by evaporating water<span> from the oceans, lakes, rivers, and even the soil. Other </span>water<span> moves from </span>plants to<span> the atmosphere through the process of transpiration.</span> Plants put down roots into the soil to draw water and nutrients<span> up into the stems </span>and leaves. Some of this water<span> is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration).

The classification of organisms is achieved in the branch of science called taxonomy. Classification is important in order for future references and understanding of the common properties and characteristics of organisms for research and easy skimming of characteristics. This is for organization and convenience purposes
Answer:
Index fossils represents the fossils of the organisms that lived in a particular geological time zone. The index fossils defines a geological time of a dead organisms. Index fossil ensures that a correct order of geological time appears in a fossil record. The index fossils of organisms that lived for a short period, were abundant and widespread geographically.
