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

6. The Environment and Energy zEnergy – the _______________ to do _______________ zAll _______________ ORGANISMS use energy for life processes.

7. Forms of Energy: z1. _______________ z2. _______________ z3. _______________ z4. _______________ z5. _______________

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

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

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

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

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

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