Which of the following order is correct in terms of the hierarchy of the organization?
a. biosphere ecosystem- population community organisnm
b. biosphere ecosystem- community population-organism
c. ecosystem-biosphere population community- organism
d. ecosystem- community- biosphere-population- organism

Neither option has the correct order.

Explanation:

The correct order in terms of organization hierarchy is "Organism, Population, Community, Ecosystem, Biome, Biosphere".

In biology, organisms are those that have the following characteristics: ability to extract energy from nutrients, adaptation to environmental changes and reproduction.

The name of population is given to the set of organisms of the same species that live in a certain area, in a certain period of time. Emphasis on area and timeframe is essential to understand that organisms of the same species that live far away do not constitute a population. As an example of population, we can mention a group of elephants that live in an area of the African Savannah.

We call community the set of various populations that live in a certain area over a certain period of time. In this case, we observe that the community is made up of a variety of organisms, unlike the population. As with the concept of population, we must keep in mind that all populations must be in the same area at the same time. As an example of community, we can cite the populations of elephants, zebras, wildebeests and lions that live in an area of the African Savannah.

The ecosystem, in turn, is a hierarchical level that encompasses the community and considers, besides these organisms, the physical environment where living beings are. Thus, in the ecosystem, we consider both biotic and abiotic factors. As an example, we can cite the African Savannah, with all its abiotic factors (water, soil and light) and the community there.

Finally, we have the biosphere, which is defined as the region of the planet where we find living beings. Simply put, we can say that the biosphere is the collection of all existing ecosystems on Earth and is considered by some to be the largest existing ecosystem.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
