Q

Ecosystem

A

Geographic area where living (plants, animals, and other organisms) and nonliving (weather, water and landscape), work together to form a bubble of life.

Q

Fossil Fuels

A

Materials such as coal, oil and natural gas, formed naturally in the Earths crust from the remains of dead animals and plants that is extracted and burned as a fuel.

16
Q

Photosynthesis

A

Process that autotrophs perform. Use sunlight energy to convert water and carbon dioxide into sugar (glucose) and oxygen.

17
Q

Cell Respiration

A

Process by which cells release energy by breaking down glucose molecules. The energy from glucose is released in the form of ATP molecules.

18
Q

ATP

A

Chemical compound that cells use to store and release energy; product of cell respiration.

19
Q

Carbon Dioxide

A

CO2 gas that is a product of Cell respiration and a reactant of photosynthesis.

20
Q

Glucose

A

Sugar/ C6H12O6; chemical energy produced during photosynthesis from light energy. Reactant in cellular respiration.

21
Q

Oxygen

A

O2 gas that is a product of photosynthesis and a reactant of cell respiration.

22
Q

Product

A

Element or compound that is PRODUCED by the chemical reaction (Think the end results)

23
Q

Reactant

A

Element or compound that ENTERS a chemical reaction (Think the ingredients)

24
Q

Water

A

H2O; liquid or vapor that is a reactant of photosynthesis and a product of respiration.

25
Where do CO2 and O2 go in and out of a plant?
Enter and exit through the stomata (tiny pores)
26
Where do water and nutrients enter the plant?
They are absorbed through the roots.
27
10% Rule
Only 10% of the energy from the lower level is passed up to the higher levels.
28
Which organisms in the food web help return nutrients to the food chain from waste or dead organic matter?
Decomposers
29
Equation for Photosynthesis:
Carbon Dioxide + Water -> Glucose + Oxygen
30
Equation for Cellular Respiration:
Glucose + Oxygen -> Carbon Dioxide + Water
31
What is ATP? What is it's purpose?
Chemical compound cells use to store and release energy.
32
What does ATP stand for?
Adenosine Phosphate (= 3 phosphates)
33
Why does photosynthesis decrease at night?
Less O2 production since theirs no sun present.
34
Aerobic
Number of ATP: 38 With O2
35
Anaerobic
Number of ATP: 2 Without O2
