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).
Mosses owe their existence to their unique adaptations for living in damp environments, such as the ability to absorb water and nutrients through their leaves and lack of vascular tissue. These adaptations enable mosses to thrive in moist habitats where other plants may struggle to survive. Additionally, mosses play important roles in ecosystems by contributing to soil formation and providing habitat for various organisms.
A limiting factor is a resource or environmental condition that restricts the growth or distribution of a population. When a limiting factor becomes scarce, it can lead to decreased population growth or even population decline as individuals struggle to survive without enough of that resource. This can ultimately impact the overall health and sustainability of the population.
In this scenario, individuals with traits that help them better adapt to the challenges have a higher chance of survival and reproduction. Over time, these advantageous traits become more common in the population through the process of natural selection, leading to a better fit between the organisms and their environment.
If a population grows larger than the carrying capacity, there will likely be increased competition for resources such as food, water, and space. This can lead to food scarcity, increased stress, and potentially higher mortality rates within the population. Over time, the population size may decrease as individuals struggle to survive in the limited environment.
Overpopulation leads to the struggle for existence because the species are unable to be supported by the insufficient resources that are available to them.

what is struggle for existence? The struggle for existence is the fight for recognition. It is defined as more than just a mere presence, but it is addressed by the realization of purpose. To examine and determine ones existence is to classify ones reason for being.
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.
It's a struggle for existence because the animals have to do many things to survive
Natural selection.
Some people have absolutely no interest and/or ability to use a search engine; in their struggle for existence they turn to Answers.com, hoping that someone else will do their work for them.
The struggle of existence & the survival of the fittest.
Hostile surrounding makes one struggle same as inferiority complex (Adler principle) does. P.S.- Both help to progress.
