Biology Matter and Energy Quiz

Question 1

Biosphere

Answer 1

Parts of the Earth where life exists. An area that contains all living organisms and the products of their activities.

Question 2

Matter

Answer 2

Something that occupies space and has mass.

Question 3

Energy

Answer 3

Ability to do work. Cannot be created or destroyed, just change forms.

Question 4

Food Chain

Answer 4

Single pathway of how food (matter and energy) moves through the organisms in an ecosystem.

Question 5

Food Web

Answer 5

All the possible food chains in the ecosystem.

Question 6

Ecosystem

Answer 6

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

Question 7

Producer/ Autotroph

Answer 7

Uses sun’s energy and nutrients to make food.

Question 8

Consumer/ Heterotroph

Answer 8

Eat producers or other consumers to make food.

Question 9

Decomposer

Answer 9

Breaks down dead organisms and other waste. Cycle nutrients.

Question 10

Carbon Cycle

Answer 10

Cycling of carbon through different reservoirs (atmosphere, fossil fuels, ocean, plants, etc.) found on earth, living and nonliving.

Question 11

Fossil Fuels

Answer 11

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.

Question 12

Stomata

Answer 12

Tiny openings on the leaves that allow gas exchange in and out; key part of photosynthesis.

Question 13

Chloroplast

Answer 13

Plant organelle that contains chlorophyll, where photosynthesis takes place.

Question 14

Chlorophyll

Answer 14

Green pigment in chloroplasts that absorbs energy from sunlight.

Question 15

Mitochondria

Answer 15

Cell organelle where cellular respiration takes place to make ATP.

Question 16

Photosynthesis

Answer 16

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

Question 17

Cell Respiration

Answer 17

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

Question 18

ATP

Answer 18

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

Question 19

Carbon Dioxide

Answer 19

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

Question 20

Glucose

Answer 20

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

Question 21

Oxygen

Answer 21

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

Question 22

Product

Answer 22

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

Question 23

Reactant

Answer 23

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

Question 24

Water

Answer 24

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

Question 25

Where do CO2 and O2 go in and out of a plant?

Answer 25

Enter and exit through the stomata (tiny pores)

Question 26

Where do water and nutrients enter the plant?

Answer 26

They are absorbed through the roots.

Question 27

10% Rule

Answer 27

Only 10% of the energy from the lower level is passed up to the higher levels.

Question 28

Which organisms in the food web help return nutrients to the food chain from waste or dead organic matter?

Answer 28

Decomposers

Question 29

Equation for Photosynthesis:

Answer 29

Carbon Dioxide + Water -> Glucose + Oxygen

Question 30

Equation for Cellular Respiration:

Answer 30

Glucose + Oxygen -> Carbon Dioxide + Water

Question 31

What is ATP? What is it’s purpose?

Answer 31

Chemical compound cells use to store and release energy.

Question 32

What does ATP stand for?

Answer 32

Adenosine Phosphate (= 3 phosphates)

Question 33

Why does photosynthesis decrease at night?

Answer 33

Less O2 production since theirs no sun present.

Question 34

Aerobic

Answer 34

Number of ATP: 38
With O2

Question 35

Anaerobic

Answer 35

Number of ATP: 2
Without O2
