What adds CO₂ to the atmosphere?

photosynthesis

decomposition

animal/plant respiration

combustion (burning fossil fuels)

Nødvendig

What removes CO₂ to the atmosphere?

animal/plant respiration

photosynthesis

decomposition

combustion (burning fossil fuels)

Nødvendig

1

How does CO₂ move through the cycle?

Plants do not contribute to the cycling of CO₂ through the environment

Animals both inhale and exhale CO₂ independent of plants

Animals absorb CO₂ from the air and fungi breathe releasing CO₂

Plants absorb CO₂ from the air and animals breathe releasing CO₂

Nødvendig

1

What happens to the carbon cycle if we kill all of the trees?
Select 2 from the options listed below:

No more photosynthesis to remove CO2

The carbon cycle remains balanced

Carbon dioxide in the atmosphere increases

Photosynthesis continues normally

Nødvendig

1

How are nutrients recycled (returned) to the soil in the nitrogen cycle?

Bacteria and decomposers

Nutrients cannot cycle through the environment

Humans and microorganisms

Plants and animals

Nødvendig

1

Why are decomposers (bacteria, fungi, and protists) important?

Bacteria consume the nitrogen and then die and decompose

Decomposers create unusable nitrogen to remove waste

Bacteria in soil convert (change) nitrogen gas into nutrients for plants to grow

Decomposers break down organisms to return/transfer nutrients/organic material to soil

Nødvendig

1

Who are the most important "character" parts of the nitrogen cycle?

Decomposers: Bacteri, fungi, and protists

Plants: Grass, bushes, trees

Animals: Worms, cows, humans

Abiotic factors: Sun, soil, rocks

Nødvendig

Question on the board:

decompose dead materials

consuming nutrients from sunlight

return nutrients to the soil

absorb water and nutrients from soil

Nødvendig

1

Question on the board:

Inorganic materials such as soil transfer energy to decomposers

Organic materials are released into the atmosphere and dissolve

Organic material returns to the soil and can later be used by plants

Inorganic materials and chemical components remain in unbalanced

1

Question on board:

More combustion from burning fossil fuels (gas) increases carbon dioxide in the atmosphere

Less combustion from burning fossil fuels (gas) decreases carbon dioxide emission to the atmosphere

More photosynthesis increases carbon dioxide in the atmosphere

Less decomposition from destroyed roads and vehicles decreases carbon dioxide in the biosphere
