Afew hundred red deer were introduced, in 1998, into a prairie ecosystem where they faced no natural predators. the graph shows the subsequent variation of the deer population in a certain area of the prairie. explain, using the concept of carrying capacity, the observed variation of the deer population over time.

The carrying capacity is the maximum size of some population. It represents the number of animals that can live, reproduce, survive in the given area regarding the indefinite sustainability of this area in terms of resources (food, water, habitat, etc.). When animals are introduced into some area, the resources are abundant. But, as the number of animals in the population grows, the resources reduces. Once the population reaches the carrying capacity the growth of population will stop (on the graph in the year 2002). With reduced resources, the competition for resources will increase, and also, animals are more prone to predators and diseases. All of this will decrease population size for a bit (on the graph year 2003).

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
