Predation
Contest:- Involves organisms usually of the same species engaging in a physical contest to gain resources.
Scramble:- All organisms in an environment trying to get as much of a resource as possible in order to survive.
Charles Darwin's theory of natural selection differed from artificial selection in that rather then a conscious agent making the selection of what will be, as in all forms of animal and plant domestication, the selecting agent is the environment itself. Now environment might be thought of as context, and just as a word finds meaning in a given context, example a paragraph, so the forms of organisms are determined by fitting properly their context or environment. All other organisms also form part of that context or environment of a given organism, more directly when there is a predator prey relationship between organisms. This predator prey relationship itself plays a selecting role, as predators tend to weed out the weak or injured in a population of prey organisms. Remember these predators are part of the organisms environmental context.
The theory of natural selection is based on the following assumptions about the nature of living things: 1. All organisms produce more offspring than can survive. 2. No two organisms are exactly alike. 3. Among organisms, there is a constant struggle for survival. 4. Individuals that possess favorable characteristics for their environment have a higher rate of survival and produce more offspring. 5. Favorable characteristics become more common in the species, and unfavorable characteristics are lost.
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.
These three ideas seem to run together, so it's important that you are able to distinguish among them. The theory that organisms change over time is evolution. The mechanism by which organisms evolve is natural selection. Survival of the fittest explains how natural selection works.Answer = Natural SelectionThe process of natural selection, of course.
That resources, food growth, expand arithmetically while populations in vrease geometrically (exponentially ), So Darwin thought this was a good observation that could be used in nature. Many more organisms are born than the environment can support, so there is a struggle for existence and the organism best suited to the environment will survive and be mire reproductively successful.
Competition. Either Contest or Scramble. Contest:- Involves organisms usually of the same species engaging in a physical contest to gain resources. Scramble:- All organisms in an environment trying to get as much of a resource as possible in order to survive.
there are more organisms in the environment than can possibly survive. This sets up a struggle to survive. The organism that are beat-suited to the environment will survive and reproduce. :)

The concept that many more organisms are born than can be supported by the resources of the environment they were born in. Thus the struggle for existence in which the better adapted organisms survive and reproduce in greater numbers than their conspecifics.
We know that organisms that must struggle to survive in a habitat with limited resources will be in competition to do so.
the struggle between organisms to survive as they attempt to use the same limited resource the struggle between organisms to survive as they attempt to use the same limited resource
Just competition.
The struggle that occurs between organisms for food and water and energy when resources are limited is called competition. Competition can kill animals.
Competition
Competition. The struggle of the fittest. The survival of the fittest.
Competition: intraspecifically (between members of the same species) or interspecifically (between members of different species).
Living beings need a certain amount of resources to live. If resources are limited then organisms must struggle against others to get enough resources to keep living.
