​How Do Organisms Interact?

• ​In the winter months, resources such as food and shelter may be limited in certain ecosystems.

• ​While bear and wolves don't typically consume one another, often times they interact when competing for food.

• ​By the end of this unit, you will understand how organisms interact.

​Can You Explain It?

• ​Look at these animals near this watering hole.

• ​How are they interacting with each other?

• ​Will these animals be able to survive if they cannot meet their need for water?

Open Ended
