Answer: there are 5 different levels of organization: cells, tissue, organs, organ systems, and organisms. All living things in the world are made up of cells. Thus, cells are grouped into tissues, so groups of tissues make up organs, and organs with a similar function are grouped into an organ system.
Explanation:
Disruptive selection.
Disruptive selection eliminates phenotypes near the average and favors the extreme phenotypes, resulting in increased genetic variation in a population.
Water is critical in all life. This is because it is important in the biochemical process of the cell. Take an example; water is consumed in most hydrolysis reaction in the body and is also significant in the regulation of blood pressure. Therefore even microbial activity will be reduced during water scarcity. Subsequently, nitrification process by nitrifying bacteria will definitely reduce in dry summers.

The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.
