Natural Selection
Question | Answer |
---|---|
Adaptation | A trait (or action) that helps an organism survive in its environment. Could be behavioral, structural, or physiological. |
Camouflage | Altering or changing something's appearance to conceal it. Allows an organism to blend into its environment. |
Competition | When many organisms are struggling to get the same resources (such as food, habitat, mates, etc.) |
resistant | When an organism has immunity to a harmful substance or a disease - it is not harmed or affected by the substance or disease. |
Diversity | The variety of different types or kinds. |
Biodiversity | The variety of different organisms/species in a given environment. |
Environment | An organism's surroundings and habitat. |
Mutation | A random change in an organisms genetic information (DNA). |
Natural Selection | Organisms best adapted to their environment are able to survive and pass on their genes. Can also be stated as "survival of the fittest". |
Overpopulation | Too many organisms in an area which can lead to competition. |
Pollutant | A man-made harmful substance that is released into the natural environment. |
Predator | An organism that preys on (hunts & kills) another organism. |
Prey | An organism that is hunted. |
Resource | Things in the environment that help an organism/species to survive, like air, water, food, shelter, a mate. (These can be used up!) |
Species | A category of organisms. A group of the same type of organisms that can mate & produce fertile offspring. |
Survival of the Fittest | Those organisms best adapted to their environment (with the best traits for their environment) will survive (& pass on their genes.) |
Variation | Small differences within a species, such as differences in hair color in humans, or differences in fur color of mice. |
well-adapted | Having good traits for a certain environment. |
stable | unchanging & steady |
