1. Food For Thought – Energy

2. Ecology • the study of the _______________ of living things to ______________________________ and their _______________ (surroundings)

3. Ecosystems • ______of the_______________ communities of an area together withthe _______________ parts of their _______________

4. Parts of an Ecosystem • _______________ community (BIOTICfactors) • _______________ input and use • _______________ cycling • _______________ environment (ABIOTICfactors)

5. Ecology involves the study of the following things: • The interactions between members of the _______________ community (the living plants, animals and microbes) • The interactions between members of the _______________ community and the _______________ environment • The interactions between the ___________environmental factors (such as light-temperature-moisture)

6. The Environment and Energy • Energy – the _______________ to do _______________ • All _______________ORGANISMS use energy for life processes.

7. Forms of Energy: • 1. _______________ • 2. _______________ • 3. _______________ • 4. _______________ • 5. _______________

8. First Law of Thermodynamics • Energy is never _______________ nor DESTROYED but is only _______________ from one form to another, or _______________ from one place to another.

9. Second Law of Thermodynamics • When _______________ is transformed or transferred, a part of the energy is LOST in the form of _______________ .

10. How organisms obtain energy • _______________ are powered by energy from the _______________ • Energy only enters living things at the _______________ level. • As energy is passed along the _______________ chain, much of it is lost as _______________ .

11. How organisms obtain energy • Energy flows ONE way through the food chain, from _______________ through _______________ . • Each level of the food chain has _______________ available energy in it.

13. Different organisms get energy in different ways • _______________ • Organisms that can make their own food (green plants) • _______________ • Organisms that cannot make their own food and have to feed on autotrophs or other heterotrophs (cows)

14. ATP (Adenosine Triphosphate) • The form of energy used by cells for cell activities • Energy stored in ATP is _______________DOWN by ATPase, an _______________, to a molecule of ADP. When that chemical bond is broken, energy is released.

15. ATP (Adenosine Triphosphate) • Without ATP all living organisms will _______________ . • All organisms get their _______________ from ATP.

16. Producers • Green _______________ • They capture light energy from the sun and convert it into food energy.

17. Consumers • are _______________that depend upon greenplants and other animals for food.

18. Types of Consumers • Primary _______________ • (Herbivores) – eat PLANTS to get energy • _______________ Consumers • (Carnivores, omnivores) – eat ANIMALS to get energy • _______________ Consumers • (Carnivores, omnivores) – eat ANIMALS to get energy

19. Decomposers • Break down and _______________ DEAD _______________ getting energy and releasing nutrients back into the environment.
