Actually, sexual reproduction can increase survival of the overall population by creating diversity. It is more effective over asexual reproduction.
An Euglena in an environment with no light has a better chance of survival because Euglenas are photosynthetic organisms that can make their own food using sunlight. Amoebas in an environment with other organisms may face competition for resources or predation, which could decrease their chances of survival.
The process that occurs is called natural selection. Organisms with advantageous genes that increase their chance of survival and reproduction are more likely to pass on these genes to future generations, resulting in a gradual change in the characteristics of the population over time.
The process of natural selection explains why organisms have different characteristics when they evolve from a common ancestor. In a given environment, individuals with variations that confer a better chance of survival and reproduction are more likely to pass on their genes to the next generation. Over time, this leads to the accumulation of different traits in different populations, resulting in species diversity.
Mutations that improve an organism's chance for survival and reproduction are typically beneficial mutations, which enhance traits such as disease resistance, adaptability to environmental changes, or efficiency in resource utilization. These mutations can lead to advantageous physical characteristics, behavioral adaptations, or improved metabolic processes, giving the organism a competitive edge. Natural selection then favors these beneficial mutations, increasing their prevalence in the population over generations. Examples include mutations that confer antibiotic resistance in bacteria or enhanced camouflage in prey species.
Asexual reproduction produces organisms that are exactly identical or clones of each other. This leaves these organisms subject to total destruction if one can be affected all can be affected. Sexual reproduction was favored because each individual in a species is slightly different. If a disease occurred in the species, there would be a good chance that some would survive.
The less of a chance of survival there is, the less organisms will survive to sexual maturity (when they are able to reproduce)
Survival and reproduction in their environment by increasing their chances of obtaining resources, avoiding predators, and successfully reproducing. These adaptations help organisms to thrive and pass on their genes to the next generation.

Adaptation
Adaptation is a trait or structure that improves an organism's chance for survival and reproduction. Benthos is organisms that live on or near the ocean bottom, sometimes attached to surfaces.
Competition can decrease the size of a population when resources become limited, increasing competition among individuals for those resources. This can lead to reduced access to food, shelter, or mates, ultimately resulting in decreased survival and reproduction rates within the population.
Some organisms possess non-ideal traits due to genetic mutations, environmental pressures, or random chance during evolution. These traits may not be advantageous for survival or reproduction, but they can persist in a population if they do not significantly impact an organism's ability to survive and reproduce.
The process that occurs is called natural selection. Organisms with advantageous genes that increase their chance of survival and reproduction are more likely to pass on these genes to future generations, resulting in a gradual change in the characteristics of the population over time.

Evolution through natural selection is a process that helps organisms increase their chance of survival. Organisms with advantageous traits are more likely to survive and reproduce, passing on these traits to the next generation. Over time, this can lead to the gradual adaptation of populations to their environment, improving their survival and reproductive success.
