1. Glossary Terms Sustainable Ecosystems

2. What is an Ecosystem? What makes up an ecosystem?

3. Ecosystem interactions between the biotic (living) organisms and the abiotic (non-living) materials and how materials and energy are transferred.

4. Ecosystem i)Biotic living or dead organisms; made up of cells. living or dead organisms; made up of cells. examples: plants, animals examples: plants, animals ii) Abiotic non-living materials; basic unit is elements also includes energy non-living materials; basic unit is elements also includes energy examples: plastic, oxygen, water, rocks, light, heat examples: plastic, oxygen, water, rocks, light, heat

5. Producers vsConsumers turn radiant (light) energy into chemical (food) energy by the process of photosynthesis turn radiant (light) energy into chemical (food) energy by the process of photosynthesis examples: plants, algae, bacteria examples: plants, algae, bacteria can not make their own food (chemical energy) can not make their own food (chemical energy) examples: cows, fish, birds examples: cows, fish, birds

6. Consumers Primary Consumer Primary Consumer –First consuming organism in a food chain –Second trophic level –Examples: herbivores or omnivores Secondary Consumer Secondary Consumer –Second consuming organism in a food chain –Third trophic level –Examples: carnivores or omnivores Tertiary Consumer Tertiary Consumer –Third consuming organism in a food chain –Fourth trophic level –Examples: carnivores or omnivores

7. Ecosystem Trophic level Trophic level –feeding level

8. Animals i) Herbivores i) Herbivores –Only eat producers ii) Carnivores ii) Carnivores –Only eat consumers iii) Omnivores iii) Omnivores –Eat producers and consumers

9. Put it all together!!! Food Chain Food Chain –starts with a producer and only connects with single links to the consumers.

10. Now it is time to create your own!! Now it is time to create your own!!

11. Last but not least! Scavengers Scavengers –Feed on bodies of larger animals –Examples: vultures; bold eagles; ravens; hyenas; some ants and beetles Detrivores Detrivores –Feed on bodies of smaller dead animals and plants and dung (feces) –Examples: crabs; earthworms; wood beetles; carpenter ants Decomposers Decomposers –Feed on any remaining dead plant and animal matter; break down the cells and get the last remaining energy –Examples: bacteria; fungi
