The abiotic factor that is essential for all aquatic ecosystem with the exception of hydro thermal vent is SUNLIGHT, THIS IS BECAUSE IT PROVIDES A SOURCE OF ENERGY.
Sunlight is very essential for aquatic ecosystems because it is the principal source of energy from which aquatic plants trap energy to make their food and provided mean of sustenance for themselves and other organisms in the water.
Deoxyribonucleoside Triphosphate, which is the more specific form of Deoxyribonucletides.
When DNA is synthesised by DNA polymerase by complimentary base pairing, 2 phosphate groups from Deoxyribonucleoside Triphosphate breaks away, releasing energy from the binding of the Deoxyribonucleotide to the adjacent Deoxyribonucleotide molecule via phosphodiester bond. These molecules will be called Deoxyribonucleoside Monophosphates.
Thus, the general name of the building block of DNA is Deoxyribonucleotide, and the more specific names depend on at which stage of DNA replication you are referring to.
Hope this helps! :)
In a survey, it says that human's DNA are 99% the same.
Hope this helps! :)
Ecologists are the persons who study the interrelationships between organisms and their environments. Like they research upon the species found in forests or deserts interact with each other and as well as their surroundings.
They test whether a species is occupying its complete fundamental niche or only a portion of it by observing if the species are expanding their range after the removal of a competitor because two species with the same fundamental niche will exclude other competing species.
