Gr.5 Evolution/Trait

Species Adaptation and Survival

Adaptation A physical trait that allows an organism to survive in their environment. Such a fur on a bear for warmth in the winter months.
Instinctual Behavior An inherited behavior that is done automatically.
Learned Behavior Learning a behavior, such a learning how to swim, can help an animal survive in their environment. This type of behavior can become a habit.
Habitual Behavior A repeated behavior, such as a bird returning to a bird feeder to get food, can help an animal survive in their environment.
Fossils Proof or evidence about how living things and environmental conditions have changed.
Catastrophic Events Volcanic eruptions, tsunami, tornado, earthquake, floods, asteroid impact can all cause the elimination of species due to changes in environmental conditions.
Camouflage The ability to blend in with the environment to protect from being hunted or to hunt for food.
Evolve To change over time; like a tadpole changes into a frog over time.
Disruptive Coloration A pattern that makes it hard to see the outline of an object, like the black and white pattern of a zebra helps the species to blend in the background.
Predator The species that hunts in a relationship, like a lion is the predator of a gazelle or zebra.
Countershading A mixture of two colors to blend in with the surrounding environment. Like the black and white color of a penguin. Above, the black color allows the penguin to blend in with dark water. Below, the white color helps the penguin blend in with the sky.
Chromatophores Specialized skin cells that allow the species to blend in - like a chameleon turns green to blend in with grass.
Mood Using color changing abilities to communicate an emotion. Like an iguana may turn red and orange to show anger.
Migration To move where the climate is warmer or to a location where more food is available.For example, monarch butterflies migrate from Michigan to Mexico during winter months.
Habit Performing the same behavior over and over to survive better; like writing in your assignment notebook to remember to do your homework makes you a better student.
Hibernation A state of dormancy or rest for a season where the bodies activities slow down. Wasps hibernate in the winter months in their nest.
Dormancy To be sleeping or like falling asleep.
Metabolism The process of breaking down food for energy; like eating breakfast and having the energy to get through your morning.
Cellular Made up of cells, like tissues are made of cells.
Endangered Very few numbers of a species in existence.
Hybrid Living things that have parents that are quite different from each other, such as donkeys and horses.
Crossbreeding A process where closing related living things are mated to create a new species.
Habitat A home for an organism.
Predator The organism that eats prey.
Mimicry In nature, when a species looks like something else.
Diversity Variety. In the animal kingdom, this refers to a group of the same kind of animal in which there are lots of animals with different traits (like dogs, cats, etc..)
