2. Entropy

Question 15

Conservation of Energy

Answer 15

Total amount of energy is constant

Question 16

Entropy

Answer 16

As more energy is transformed, more is wasted

Question 17

Aerobic respiration equation

Answer 17

C6H12O6+6O2= 6CO2+6H2O + energy
(oxygen-used-to-make-energy-from-carbs)

Question 18

What does aerobic respiration do

Answer 18

Uses O2 to convert Glucose to Energy

Question 19

Photosynthesis equation

Answer 19

6CO2+6H2O+ solar= C6H12O6+6O2

Question 20

What does photosynthesis do

Answer 20

Converts sunlight, water and CO2 to create O2 and energy in the form of sugar

Question 21

Producers (autotroph)

Answer 21

Make nutrients themselves

Question 22

Biomass

Answer 22

Living organic material (wood, plants, garbage)

Question 23

Chemosynthesis

Answer 23

Heat is used to convert inorganic compounds into nutrients (what bacteria that don’t get sun do instead of photosynthesis)

Question 24

Consumer (heterotroph)

Answer 24

Eats other animals/plants, Can’t make their own energy

Question 25

Biomagnification

Answer 25

When a pollutant moves up the food chain because consumers eat all of toxin in prey (fertilizer, chemicals)

Question 26
