The division is a taxonomic rank in classifications of the biological organisms used separately in the botany and zoology kingdom. In the botany, the kingdom division is equivalent to the phylum. They include Marchantiophyta, Anthocerotophyta and other phylum-level groups of organisms.
In the zoological kingdom, division refers to a rank use to superordinate to the cohort and subordinate to the infraclass. Living tetrapods are classified to the rank as Divisions Amniota and Amphibia within the group of fleshy limb vertebrates.
Division is one of the taxa present in the scientific classification of living beings. The division is the taxon corresponding to the phylum, but the name "division" is used to classify plants and fungi. Like the phylum, the division groups beings that are more biologically related than living beings grouped in kingdoms and less biologically related than living beings grouped in classes.
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
The energy of the ecosystem can be best described as option C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.
