Living things meet their needs through interaction with the enviornment
An environment is simply everything that surrounds a living thing.
*The Arctic, penguin and ice.
*The Forest, squirrel and dirt.
*The Desert, lizard and sand.
*The Ocean, fish and water.
*The Prairie, prairie dogs and rocks.
(This is a wolf in the woods.)
A interaction is when two or more living things do something that effects the other.
*A bee and flower, the flower gives a bee pollen so they can make food (honey) and the bee spreads the pollen so more flowers can grow.
*Remora and Sharks, the Remora cleans of the shark while the Shark feeds the Remora with the stuff it eats off of it's stomach and the shark acts as a taxi, it helps it get to places quicker.
* Worm and soil, the worm turns around and sifts the soil and makes it a healthy soil while the soil gives the worm a home and shelter.
* Humans and plants, humans breathe out carbon dioxin which is the air that plants need while plants give out oxygen, what humans need to breathe.
* A tiger and deer, the tiger hunts the deer and the deer gives him a nice supper :)

* 1,000,000 types of flowers.
* 350+ breeds of horses.

The process of something adapting, or modifying.
* Geese migrating.
* Flowers closing at night.
* A caterpillar turning into a butterfly.
* Larva turning into a ladybug.
* A North American Wood Frog freezing when it touches snow or ice.
