An organisms survival depends upon many things. We are going to try to determine some adaptations that help organisms to survive.
The combination of physical traits and behaviors that helps organisms to survive and reproduce in their environment is called fitness. Fitness arises through a process called adaptation. Successful adaptations enable organisms to become better suited to their environment, better able to survive and reproduce. The word adaptation also describes any inherited characteristics that increase an animal's or plant's fitness for survival. Thus, the long neck and legs of a giraffe are adaptations that permit giraffes to feed on the leaves of trees. With these adaptations, giraffes can eat leaves too high for most grazing animals to eat and thus are better able to survive and reproduce, passing their genes on to their young.
How is adaptation related to fitness?
make a collage using different photographs that the students cut from magazines that illustrate the differences in organisms. Such as-body covering, leg or neck length, types of movement.
We have learned that different characteristics increase a plant or animals fitness. On your paper give two examples of adaptations animals could make to help them survive.
fitness-a combination of physical traits that enable organisms to survive
adaptation-inherited characteristics that increase an animals ability for survival
