Competition is a driving force behind natural selection. Which of these statements best describes why competition is a constant pressure?

The options are not given, here are the options gotten from another website.

A. Organisms produce more offspring than can survive

B. Organisms are taught to fight others of the same species

C. Organisms are taught to fight others of the same species

D. Multiple species fill the same niche and competition will always arise against other species

The correct option is D.

Multiple species fill the same niche and competition will always arise against other species.

Explanation:

This is because competition arises when different organisms living a niche compete for space or resources and this can be as a result of too much population in a niche and limited resources and space. Organisms tend to compete for survival which is the driving force of natural selection.

These u because as competition rises, species tend to develop traits which will help them to survive, adapt , reproduce and compete well in their environment an this result in survival of the fittestthat is those that can adapt well.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
