Answer:
In all these environments, organisms interact and use available resources, such as food, space, light, heat, water, air, and shelter. Each population of organisms, and the individuals within it, interact in specific ways that are limited by and can benefit from other organisms.
1. In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment.
2.???
3.Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
4. Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
5. Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms
6.When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.
7. In all these environments, organisms interact and use available resources, such as food, space, light, heat, water, air, and shelter. Each population of organisms, and the individuals within it, interact in specific ways that are limited by and can benefit from other organisms.
