Ecology Ecology is the study of living organisms and there relationship with there non living features in an ecosystem. For examples a fish interacts with the non living features in his ecosystem, like the water, temperature, air, and the sun.

Ecosystem An ecosystem is an area in the world where living and non living features interacts with each other. Ecosystems can be as small as a fish tank and as big the world we live in. Lets take your neighborhood park for example, think of all the living organisms: squirrels, birds, chipmunks, and plants. Then think about all the non living features: the temperature, the water, the soil, the air, the rain, sun. For example the plants interact with the sun, soil, and temperature; with bad soil the plant can't grow, without the sun it can't make food and if the temperature is to low or to high the plant will die.

How do animals relate with each other?
Limiting Factors in populations A limiting factor in a population is something that stops a population of over growing. For example the lions in Africa stop the population of antelopes to over grow.	Animal Diversity The animal diversity is how many different animals there in an ecosystem. For example in the Pacific Ocean their are more then 2000 different species of animals and fish. A diversity is key for the survival of an ecosystem. without a diversity an ecosystem could not survive because without the diversity there would be no animal to be a limiting factor, no herbivores to eat the plants, etc.
Symbiotic Relationship There are three different symbiotic relationships: Mutualism, commensalism, and Parasitism. Mutualism: mutualism is a relationship where two animals interact with each other and both benefit. For example the clown fish, and the sea anemone have a mutualism relationship, the clown fish cleans the sea anemone and the sea anemone protects the clown fish. Commensalism: commensalism is a relationship where one animal benefits and the other animal is not affected. For example the shark and the pilot fish have a commensalism relationship, the pilot fish follow the shark and eat left over meat of the sharks meal. Parasitism: parasitism is when one animal benefits and the other is hurt. For example the tape worm and the horse have a parasitism relationship, the tape worm goes into the horses body and eats all its nutrients, after a while the horse dies.

Animal Adaptations
To survive in there ecosystem animals have had to adapt, this is called animal adaptation. If animals could not adapt to there ecosystem they would soon die if any major change should happen. The process of animal adaptation takes thousands to millions of years. Another name for animal adaptation is called evolution. A big example of animal adaptation are the Galapagos islands. On these islands researchers have found common animals who have adapted to there situation: swimming iguanas, biggest land turtle in the world, researchers have also found non flying birds who did not need to fly so have adapted to using there wings to become better swimmers in water to catch there food.
The Frog has adapted to its environment with its nocturnal site, camouflage to hide from predators, selective hearing, permeable skin to absorb the water when swimming, a long tong to catch its pray, and toe pads.	The Owl has adapted to its ecosystem with large eyes to see farther and better in the dark, talons to catch there pray, silent feather so catch there'd, camouflage, and very good hearing.
