What is the relationship between natural selection and population?Natural selection can cause microevolution (change in allele frequency), which causes fitness-enhancing alleles to become more common in the population. Fitness is a measure of reproductive success (how many offspring an organism leaves for the next generation, relative to others in the group).
Another factor that limits the growth of populations is densification. This means that a large number of individuals present at the same time in the same area reduces the availability of resources for the population as a whole, increasing the mortality rate and reducing reproductive success.

Plant viability depends on heterotrophs' capacity to mineralize vital components. All mammals and fungi are heterotrophs, as are the majority of opisthokonts and prokaryotes.
What are the different organism in an ecosystem?In ecosystems, biotic and abiotic factors—or nonliving components—coexist. Biotic factors include plants, animals, and other species. Abiotic factors include temperature and humidity in addition to rocks.
Aiding in the germination and distribution of various plant seeds throughout an ecosystem.
Chemoheterotrophs include herbivores, predators, scavengers, and decomposers.
Materials from chemoautotrophs and chemoheterotrophs are recycled by chemoheterotrophs and employed repeatedly in a complex web of life.
Therefore, Symbiotic connections between some organisms and autotrophs allow them to obtain organic carbon, such as corals.

The correct answer is - Reproductive isolation occurred through behavioral isolation.
Explanation:
Behavioral isolation is a type of isolation that takes place due to the beginning to develop different behaviors in populations of the same species which is not preferred by these different populations.
Due to this behavioral isolation, these populations show reproductive isolation and new species form. The most common example of behavioral differences is mating calls.

Answer:
3. theory → a. The outer layer of the Earth is divided into plates that move due to convection currents under the surface.
2. hypothesis → b. If the amount of daylight increases plant growth, then plants will have higher rates of growth during the summer.
1. law → c. For every action or force in nature, there is an equal and opposite reaction.
Explanation:
THEORY
The scientific theory explains facts or the cause of natural phenomena and makes predictions about them. It is based upon direct observation and scientific methodology.
The theory is fundamental to science because it allows scientists to organize and understand observations.
HYPOTHESIS
A hypothesis is a prediction done by the researcher when trying to answer a problem question. It is a conjecture, which has not been verified yey, nor refused, and that requires corroboration. It is a possibility, but not a fact. The researcher performs the experiment and concludes if the hypothesis is rejected or accepted. The prediction must be objective, expressed in a comprehensive manner, and reflect a logical relation between the variables involved in the experiment.
LAW
Law is a statement that establishes a relationship between variables explaining the cause of natural phenomena. It is based upon empirical information and evidence obtained after many repeated experiments and observations. Many scientists agree with the statement and use it to perform a research project. A law cannot be changed.
