What is the most important concept in Darwin's theory of evolution by natural selection?
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.
Natural selection is based on what 5 observations?
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.
Is the struggle between organisms to survive in a habitat with limited resources called the natural selection?
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.
What process did Darwin's book suggest that organisms evolve through?
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.
What ideas about plants and animals did malthus's work suggest to darwin?
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.
What is a relationship in which organisms struggle with one another to obtain the material they need to live?
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.

What are the major pointa to the theory of evloution by natural slection?
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 struggle between organisms for the limited resources in a habitat?
Competition: intraspecifically (between members of the same species) or interspecifically (between members of different species).
What are organisms that are not well adapted?
Organisms that are not well adapted may struggle to survive and reproduce in their environment. This can result in low fitness, decreased reproductive success, and ultimately may lead to population decline or extinction. Factors that contribute to poor adaptation can include changes in the environment or competition from other species.
Why do all organisms face a struggle to survive when natural resources are limited?
Organisms need resources like food, water, shelter, and space to survive and reproduce. When resources are limited, competition among organisms increases as they struggle to meet their survival needs, which can result in some organisms with better adaptations outcompeting others. This competition is a fundamental aspect of natural selection and drives the evolution of traits that enhance an organism's ability to survive and reproduce in its environment.
What is the struggle of organisms for the same limited resources called?
This struggle is called competition. Organisms compete with each other for resources such as food, water, and space in order to survive and reproduce.
What is The struggle between organisms of the same species for limited resources?
We know that organisms that must struggle to survive in a habitat with limited resources will be in competition to do so.
How does competition influence the relationship between organisms in the field of biology?
Competition in biology refers to the struggle between organisms for resources like food, water, and space. This competition can influence the relationship between organisms by leading to adaptations that help them survive and reproduce. Organisms may evolve traits that give them a competitive advantage, such as better camouflage or faster running speed. Ultimately, competition plays a crucial role in shaping the dynamics of ecosystems and the evolution of species.
Is rawlings perfect competition?
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
What did he call this struggle for existence?
He referred to this struggle for existence as "natural selection." This concept describes the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution, highlighting how certain traits become more common in a population over generations.
What happens when previous adaptations are no longer suitable for changes in the environment?
When previous adaptations are no longer suitable for changes in the environment, organisms may struggle to survive and reproduce effectively. This can lead to a decrease in population size or even extinction if the adaptations are not able to keep up with the changing conditions. Organisms that are unable to adapt to the new environment may face increased competition for resources and may be outcompeted by better-adapted species.
