1. Ecosystems

2. Biotic vs. Abiotic Factors
Biotic-living (plants, worms, bacteria, etc.)
-Abiotic-nonliving (soil, water, oxygen, etc.)

3. Organization of Ecosystem

4. SPECIES
Group of organisms that can produce fertile offspring. This means the offspring can mat and produce more fertile offspring so the species continues.

5. Populations
All the members of one species living in a particular area

6. Communities
A particular area containing more than one species of organisms
All the different populations in an area

7. Ecosystems
Community of organisms living in an area along with their non living environment
Ex. Deserts, ponds, oceans, forests, etc.

8. Producer
Plants are called producers. This is because they produce their own food(glucose) through photosynthesis.
H2O+ CO2 + light --→
C6H12O6 + O2 + energy
Glucose is C6H12O6

9. Consumer
Animals are called consumers. They cannot make their own food-Consume (eat) plants and/or animals.

10. Types of Consumers Herbivores eat plants Carnivores eat other animals
Omnivores-eat both
Scavengers-eat dead organisms

11. Decomposer
Break down waste and dead organisms to return the raw material to the ecosystem.

12. Food Chains and Food Webs
Show energy moving through an ecosystem
Food webs are made of more than one chain
