This or That

100

Which process is this: Cellular Respiration, or Photosynthesis?

_{Glucose + Oxygen} → _{Carbon Dioxide + Water + Energy (ATP)}

Cellular Respiration

200

This process puts carbon IN plants.

Is it: Photosynthesis, Cellular Respiration, or Decomposition?

Photosynthesis

300

This process uses CO₂ from the atmosphere.
 
Is it Cellular Respiration, or Photosynthesis?

Photosynthesis

400

Which process takes carbon OUT of plants...

Is it: Photosynthesis, or Decomposition?

Decomposition

500

Which process is similar to fire... 

Same process. Different conditions. Different rate (speed).

Is it: Photosynthesis, Cellular Respiration, or Decomposition?

Decomposition

Zombies

100

The process where dead plants and animals are broken down by living things.

Decomposition

or Decompose

200

Name 2 decomposers

Bacteria

Fungi

Worms

Insects

300

Dead plants and animals must be broken down in order for their parts to be used again.

What type of organisms carry out this process? 

Decomposers

400

TRUE or FALSE:  All organisms decompose at the same rates (speeds).

FALSE 

- why? (bonus points)

500

Give 2 reasons why decomposition slows down

Cold temperatures

Low oxygen

Vocabulary

100

Solar Radiation

Sunlight

200

Rates

speed of something

300

Frozen, water-logged dead plant layers

HINT:  like a freezer

Permafrost

400

Stuff changes form but doesn’t disappear

HINT:  atoms can be rearranged to make new molecules

Matter Transformation

500

A place that traps carbon instead of releasing it

HINT:  like a fridge (refrigerator)

Carbon Sink

Carbon Cycle

100

Photosynthesis releases ____________ into the atmosphere.

oxygen

200

What is the chemical formula for Photosynthesis?

CO₂ + H₂O + Sunlight → C₆H₁₂O₆ + O₂

_{-50 Less points but still acceptable:}

_{Carbon Dioxide + Water + Sun → Sugar + Oxygen}

300

TRUE or FALSE:  When molecules break down and become something else, sometimes the atoms disappear. 

FALSE

... why? (bonus points)

400

TRUE or FALSE: Carbon does not always get used as energy and can stay trapped in the ground when decomposition slows down.

TRUE

... WHY/HOW? (Bonus Points)

500

Name two ways that carbon (usually in the form of CO₂) returns to the atmosphere.

Respiration

Decomposition

Burning / Combustion

Fire

100

Name the 3 components needed to create a fire

Oxygen

Fuel

Heat/Energy

200

In fire, the chemical energy is released as these 2 things:  _________  and  __________

heat

light

300

What gas is released when something burns?

Carbon Dioxide

400

Name 3 characteristics of fire

Very fast

Bright

Needs high temp to start

Chemical reactions OUTSIDE the cell in the environment

500
