Adaptations, interdependence and competition GapFill

All living organisms belong to a particular  familycommunitybiomeecosystemhabitatbiosystem. This can be small, such as a mouldy apple, with organisms including bacteria and fungi, or as large as a rainforest, with an incredible variety of species. Every organism is dependent on another for survival, and in some cases the survival of one species can be directly affected by the presence of another. This is called  reliancerecessivenessinterdependencedominanceindependencecodominance, and includes certain species of plant relying directly upon certain insects to  evolvefeedeatpollinatedispersesignal their flowers.

All factors that can affect life in these systems can be divided into two groups: biotic and  abioticinorganicinertunnaturallifelessnon-biotic. The biotic factors can include how much  foodmoisturewindpressurespacewarmth there is for organisms, the presence of predators or  ecosystemspathogenspreychemicalsfoodrocks that can cause disease, and competition which can limit breeding and survival of organisms. The non-living factors which can affect organism survival are much more vast. For example, light intensity can affect many organisms, but most directly plants which are performing  respirationtranscriptionphotosynthesismetabolismdeforestationmitosis. This process can also be affected by  hydrogencalciumzincsodiumoxygenwater availability and carbon dioxide levels. Temperature and the pH of soil or water can also have a direct effect on species.

In many instances, the amount of each of these factors will be at the ideal amount for all organisms, and in these cases, the system is described as a  climax biosystemperfect biomefixed ecosystemclosed systemfixed factor systemstable community. Generally this occurs because organisms are well  situatedenergisedclassifiedgenerateddesignedadapted to live in their environment through the process of natural selection. There are even some organisms that can survive in extreme environments which would be inhospitable to many other species, and these are called  apex predatorspathogensbioconsumersadaptophilesextremophilesretroviruses.
