1. Ecology
Ecology is the study of how living things interact in an environment.

2. Ecosystem
An ecosystem consists of the living things and their environment

3. Biotic Factors
The living things in an ecosystem are called BIOTIC factors.
Examples of biotic factors are plants, birds, and animals.

4. Abiotic Factors
The nonliving parts of an ecosystem are called ABIOTIC factors.
Examples of abiotic factors are light , temperature, water, atmosphere, and soil.

6. 6CO2 + 6H2O + sunlight & chlorophyll C6H12O6 + 6O2
Begins with the SUN
Photosynthesis
6CO2 + 6H2O + sunlight & chlorophyll C6H12O6 + 6O2

7. Organisms that can make glucose during photosynthesis are called PRODUCERS.

8. Producers use most of the energy they make for themselves.

9. The energy that is not used by producers can be passed on to organisms that cannot make their own energy.

10. Organisms that cannot make their own energy are called CONSUMERS.

11. Feeds on plant and animal remains
Types of Consumers
Herbivores - Eat plants
Carnivores - Eat meat
Omnivores - Eat Both
Decomposers
Feeds on plant and animal remains

12. Consumers that eat producers to get energy:
Are first order or primary consumers
Are herbivores (plant-eaters)

13. Most of the energy the primary consumer gets from the producer is used by the consumer.

14. Some of the energy moves into the atmosphere as heat.

15. Some energy in the primary consumer is not lost to the atmosphere or used by the consumer itself. This energy is available for another consumer.

16. A consumer that eats another consumer for energy:
Is called a secondary or second order consumer
May be a carnivore or an omnivore

17. Most of the energy the secondary consumer gets from the primary consumer is used by the secondary consumer.

18. Some of the energy is lost as heat, but some energy is stored and can passed on to another consumer.

19. A consumer that eats a consumer that already ate a consumer:
Is called a third order or tertiary consumer
May be a carnivore or an omnivore

20. Consumers that eat other consumers that have already died are called scavengers.

21. Decomposers are organisms that break down dead or decaying organisms
Gives nutrients back to the soil
Examples: worms, fungi, bacteria, etc.

22. The transfer of energy from sun to producer to primary consumer to secondary consumer to tertiary consumer can be shown in a FOOD CHAIN.

24. Another way of showing the transfer of energy in an ecosystem is the ENERGY PYRAMID.

25. Energy pyramids show
That the amount of available energy decreases down the food chain
It takes a large number of producers to support a small number of primary consumers
It takes a large number of primary consumers to support a small number of secondary consumers

26. Food Webs: Are interconnected food chains
They show the feeding relationships in an ecosystem

30. Our Energy Pyramid Construct an energy pyramid of yourself
Label the level of the pyramid
Label and draw a picture of each food item
Make sure your name is on it!
Choose one item and make a food chain (must be at least three long)
