Adaptation Flashcards
What is an adaptation?
A physical structure or behavior that provides a species a better chance at survival AND reproduction.
When is an organ considered to be an adaptation?
If an organ serves a relatively unique function then its considered a adaptation
What are some examples of organs or functions that are not considered an adaptation?
Organs or functions that are needed for survival. An example is a cow having a heart and being able to urinate. Those two things are not adaptations.
What can long term environmental changes cause?
Changes in environments may prompt adaptations in the population of a species.
What is population?
A group of the same species living together in the same area.
What would you classify a forest fire and deforestation as?
Short-Term Environmental changes
Long-Term Environmental changes
List examples of events that result in short-term environmental changes.
Which type of environmental change affects species over generations as they adapt to survive over the centuries it takes for this environment to develop?
A Long-Term Environmental change.
What are some examples of short-term environmental changes?
Forest fires, Floods, Earthquakes, Tornado, Tsunami, Blizzards ect.
What are examples of Long term evnvironmental change?
Island formation
Mountain formation
Glaciers moving and melting
How do species survive after a short-term environmental change occurs?
They end up having to adapt to their environment in order to survive and not die off.
How do species survive after a long-term environmental change occurs?
They either adapt to their environment, relocate, or become extinct.
Define natural selection?
The process where organisms with the survive and reproduce pass on genes/trait on to their offspring.
What are the organisms that are best fit for the environment that survive called?
Survival of the Fittest
What would poision & vemon and speed be in adaptations
Structural and behavioral adaptations
