1. Unit 2: Ecology and Biodiversity

2. Remember!!!!!
Write all notes in your note book, using the indents and titles
If the title repeats, then you do not need to rewrite it again
Highlight all vocab words that are bolded, and highlight all things that say definition so you will be able to find them later
If there are directions for you to draw something, you must draw that in your notes.

3. How is the biosphere related to ecology?
What is the biosphere?
Definition All living things on this planet
Examples: Animals, plants, insects, bacteria, fungi, humans
What does ecology study?
Definition The study of relations between organisms and their physical environment
So ecology studies all the organisms in the biosphere and the places that they live

4. Ecology studies Ecosystems
Definition A community of organism and the environment they live in
Ecosystems are made of abiotic and biotic factors
Biotic Factors
Abiotic Factors
Definition A living factor that affects an organism
Examples: Food Predators Diseases
Definition Nonliving condition that affects an organism
Examples: Climate Water Gases Soils

5. Ecosystems are everywhere
Ecosystems have their abiotic and biotic interact with each other all the time
Examples
Plants (biotic) need sunlight, carbon dioxide, water, and soil nutrients (abiotic) to survive
Animals (biotic) need food (biotic), water, and oxygen (abiotic) to survive
