1. Which part of photosynthesis do humans benefit from?O2 = oxygen

2. Which part of photosynthesis represents the food for the plant?
C6H12O6 = glucose

3. Identify the ELEMENTS in the following equation:
6H2O + 6CO2 C6H12O6 + 6O2
H = hydrogenO = oxygenC = carbon

4. Super Brain Question!
How many ATOMS are in the equation6CO2 + 6H2O = C6H12O6 + 6O2 ?
For 6CO2, Think: (1 carbon + 2 oxygen) x 6 = 3x6
=18
18 + 18 = 24 + 12
36 = 36Reactants = 36 atoms Products =
36 atoms The atoms are the same. They just re-
group!

5. What type of energy transfer occurs during photosynthesis?
Radiant energy becomes chemical energy

9. What is the process that starts a food web?
Photosynthesis
What is the main source of energy in an energy pyramid?
That’s the same sun from the other slide!

10. What did the Gatorade activity demonstrate?
It showed how energy is lost as it moves up the energy pyramid from one level to the next.

11. Decomposers
Decomposers are organisms that break down organic material. They are important, because they return nutrients to the soil.
worms
bacteria
fungi

12. Scavengers
Scavengers are animals that feed off the dead bodies of other animals.
Buzzards (top) and vultures (bottom) clean up ecosystems and recycle the energy.

13 & 14. Autotroph and Heterotroph
An autotroph is an organism that makes its own food.
auto = self;
It makes food for itself.
A heterotroph gets its food by consuming another organism.
hetero = different
It gets its food from a different organism.

15. Biodiversity vs. Monoculture
biodiversity: the variety of species living in an area; the more species there are, the greater the biodiversity
monoculture: an area where only one species lives
(prefix “mono” = one)
![Page 16: Biotic Interactions Review Test Date: October 9 th, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062519/5697c0031a28abf838cc3728/html5/thumbnails/16.jpg)
16. How does biodiversity contribute to the sustainability of an ecosystem?
Biodiversity makes an ecosystem more sustainable.
If one species is lost, the ecosystem can still survive.
(Remember the Douglas Firs activity!)

24. Energy Transformation
energy transformation: the process of changing
energy from one form to another
![Page 23: Biotic Interactions Review Test Date: October 9 th, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062519/5697c0031a28abf838cc3728/html5/thumbnails/23.jpg)
24. & 25. Elements and Compounds
element: any substance that cannot be broken down into simpler substances.
compound: two or more elements chemically
bonded together in a set ratio
![Page 24: Biotic Interactions Review Test Date: October 9 th, 2015.](https://reader036.fdocuments.us/reader036/viewer/2022062519/5697c0031a28abf838cc3728/html5/thumbnails/24.jpg)
26. Manipulated (independent) and responding (dependent) variablesKeeping the lights on for different amounts of time each day affected the number of eggs chickens laid.
Does the amount of time the lights are on depend on the number of eggs laid?
OR
Does the number of eggs laid depend on the amount of time the lights are on?
Number of eggs depends on amount of time lights are on, so… Dependent = number
of eggs laid Independent = amount
of time lights are on
