When in a certain situation, organisms with traits more suited to survive in that situation often survive more often and are able to reproduce more, which means that their genes eventually dominate the gene pool.
For example: take a light moth population and a dark moth population. They live in a forest with dark trees, so the dark moths blend in more and are harder to find and hunt. As a result, more of them survive than the light moths, so more of them are reproducing and passing their genes along.
Over time, those genes may become the only traits of that variety that the organism can have, so they grow to evolve and adapt to their surroundings.
Answer:
All of the above occur.
Explanation:
Symbiotic Nitrogen Fixation (BNF) is a natural process that occurs in combinations of plants with diazotrophic bacteria. Its main product, nitrogen, is an essential nutrient for plant growth and development. The nutrient is captured from the air and fixed by diazotrophic bacteria found in many soil types. In the roots, noduliferous bacteria generally have high specificity for each plant species, being common, for example, the symbiosis between plants of the Leguminosae family and diazotrophic bacteria known as rhizobia.
This fixation process has many positive points, among which we can mention that in this process the plant benefits from the use of an infinite source of nitrogen, the soil benefits from being naturally fertilized and the bacteria from the photosynthesis of the plant. plant.
