Unit 4: Organisms and their environment

Ecology:the branch of biology that deals with the relationships between organisms and to their environment.
Essentials for survival: All living organisms depend on three thing in their environment.
Supply of food
Shelter from undesirable physical conditions
A breeding site
Changing with the seasons: As the seasons change, the ability for the habitat to supply the organism with their requirement may change depending on the time of the year. For example, if the organism does better in the heat and has very little hair to keep it warm, it will do better in the summer rather than in the winter when it's cold.

As the organism's requirements deplet they may leave. These will then be followed by the predators who will feed on them. Animals usually migrate due to changing conditions in the animal's environment.

When the fox has a lot of food,it stashes away the leftover food for later use. They do this by digging holes and storing it underground, whether in soil or snow. They also usually hide it under layers of things such as leafs and grass. they also pee on it to mark it as their territory.
Strong Senses:Red foxes are highly effective hunters, and have very strong senses to help them. They have a good sense of smell, vision and hearing. They are capable of picking up on low frequencies so they are able to go after tiny creatures, as many of their typical prey animals are.
Fast Running:Red Foxes are extremely fast runners, this helps them survive. If a red fox is faced with a threat from predators such as gray wolves, coyotes or a bobcat they can often get away by running away. Not only are they extremely fast runners, they have lots of stamina, as well. Their tiny stomachs and lengthy limbs enable them to plow through at close to 30 miles per hour. As slight and trim creatures, running is a major advantage for
