1. Sea Otter Activity:
Each person needs to first read through the handout.
Then, work with your partner on the second part.
Each group member is to only have ONE electronic device they are researching on.
Answer the questions on a separate piece of paper.

2. Key Concepts
Marine and terrestrial environments are interrelated, interactive, and interdependent.
The ocean is an important source of food and other resources for humans.
Marine biology is the study of the sea’s diverse inhabitants and their relationships to each other and their environment.
