Natural Selection, Ecology, Human Impacts
Questions and Answers
Evolution - ✅✅Change of features of a population/specie over time, as a result of natural selection
Variation - ✅✅Any difference between individuals of the same species.
Species - ✅✅A group of similar organisms that can breed and produce fertile offspring.
Mutation - ✅✅Change of DNA within a gene or chromosome, this is how alleles are made. Leads to
adaptation
Adaptation - ✅✅heritable characteristic that increases an organism's ability to survive and reproduce
in an environment
Organism - ✅✅A living thing
Population - ✅✅All the organisms of one specie in an area
Communities - ✅✅Different populations interacting in an area
Ecosystem - ✅✅A biological community of interacting organisms and their physical environment.
Autotrophs - ✅✅Organisms that make their own nutrition using energy from the environment (e.g.,
photosynthesis)
Hetertroph - ✅✅An organism that gets its nutrition and energy by feeding on other living organisms.
Decomposers - ✅✅chemically break down organic matter using enzymes
