There is a constant struggle for survival among organisms within a population because they are all competing for the same resources. Since resources are limited, some of the organisms may end up without the things they need for survival.

What is the term used when a struggle occurs between organisms for food water and energy when resources are limited?
Competition. The struggle of the fittest. The survival of the fittest.
Why are earthquakes a density independent factor limiting human population growth?
Earthquakes causes death of organisms despite the numbers present in the population. Hence it is an density independent factor. The impact of the earthquake is the same even if the population is 100 or 1000. It also does not depend on whether the organisms possess traits that aid in their survival.
What is the difference between the meanings of the terms evolution and natural selection?
Evolution is the change in allele frequency over time in a population of organisms. Change over time and a fact. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms and explains much about the fact of evolution.
Where do organisms live that provide food shelter moister and temperature needed for survival?
Habitat
What body parts does a flamingo use for survival?
All of them. As do all other organisms, including you.
What is the term used when a struggle occurs between organisms for food water and energy when resources are limited?
Competition. The struggle of the fittest. The survival of the fittest.
Is the struggle between organisms to survive in a habitat with limited resources called natural resources?
Survival of the fitest
Is the struggle between organisms to survive in a habitat with limited resources called a natural selection?
Survival of the fitest
Why are Darwin's ideas classified as a scientific theory?
Because he studied organisms very closely and propounded the theory of evolution with the phrase 'Struggle for existence and survival of the fittest organisms'.
What is survival to the fittest?
Natural selection conceived of as a struggle for life in which only those organisms best adapted to existing conditions are able to survive and reproduce.
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.
What does struggle mean in a scientific term?
survival
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.
Why do you think Darwin considered the phrase the struggle to survive an appropriate description of natural selection?
Because in the wild there is a struggle for existence as more organisms are born than there are resources to support them. Thus, there is a wide variety of traits expressed by these many organisms and some of these traits confer survival and reproductive advantages which is what natural selection is selecting for.
How did Charles Darwin relate his work to Thomas Malthus?
According to Malthus, when food production is more than is needed by the population, the population increases; if population grows too much faster than food production, the population growth is slowed by famine, disease, and war.
Why does biodiversity enable organisms to have a better chance of survival?
how does biodiversity in an ecosystem increases the chances of survival for organisms
What are three components of natural selection?
The three parts of Darwin's theory of evolution by natural selection are struggle for existence (competition), survival of the fittest (those with the best adaptations for the time/environment live and reproduce), and descent with modification (over time the population is more representative of organisms with the best adaptations).
