Every organism has a unique biome within which it lives. Aquatic or terrestrial. This eco-region is its natural habitat. This location is where the basic needs of the organism are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive, reproduce and continue to keep their species alive.
Organisms adapt to survive the climatic conditions of the ecosystem, survive against predators, and other species that they compete with for the same food and space. An adaptation is a modification or change in the organism's body or behavior that enables it to survive against all odds. These slow changes, over time allow the favorable traits to be passed on and accumulate in a population while the less favorable traits slowly disappear. Charles Darwin noticed these variations among organisms of the same species and developed his theory of Natural Selection.
An animal may adapt to its habitat in different ways. It may be a physical or structural adaptation, just as the limbs of birds have modified into wings or the way the cheetah is shaped for running at a fast speed. Even a plants spikes or thorns are physical adaptations. Adaptations may also be physiological in the way the body works in circulating and respiration, for instance the gills that fish have enable them to breathe in water.

Finally an adaptations may be behavioral which tends to be traits that are acquired by the organism after birth, such as migration, living in herds or packs, even burrowing to escape the midday sun.Or it may be the way the animal behaves whether it is hunting for food, or running fast to avoid predators or migrating to other places for food or survival.
Before researching these adaptations students began to fill out the board with examples both written and drawn. Then slowly over two days they added examples and began to see the full picture of how behavioral, physiological and physical traits can be unique to one ecosystem or can overlap. There are many traits you find in every biome on Earth. Creating a giant chart (still displayed) is allowing students to modify as they continue to learn and grow as a class.
