what type of organisms do photosynthesis

What are autotrophs/producers

100

Plants help in the process of the carbon cycle by taking in ____ from the atmosphere.

What is CO2?

100

which organisms perform Cellular respiration.

all living things

100

Name one organism that can performs the process of decomposition

What is fungi/ bacteria?

100
This process occurs when humans burn fossil fuels.
What is combustion?
200

The  are the products of photosynthesis

What is Oxygen(O2) and Glucose (C6H12O6)?

200

Role of plants in the carbon cycle?


  • Plants absorb carbon dioxide (CO2CO_2CO2) from the atmosphere during photosynthesis.
  • They use sunlight, CO2CO_2CO2, and water to produce glucose (C6H12O6C_6H_{12}O_6C6H12O6) and release oxygen (O2O_2O2). 6CO2+6H2O+light energy→C6H12O6+6O26CO_2 + 6H_2O + \text{light energy} \rightarrow C_6H_{12}O_6 + 6O_26CO2+6H2O+light energy→C6H12O6+6O2
  • This process reduces atmospheric CO2CO_2CO2 levels, acting as a carbon sink.
200

What are reactants of Cellular respiration.

Oxygen(O2) and Glucose (C6H12O6)

200

How does carbon move between living organisms and the atmosphere?

Through  cellular respiration and photosynthesis



200
Humans use fossil fuels when they _____ .
What is drive vehicles, use factories for production, use electricity, have a fire.
300

Which type of energy is converted during photosynthesis?

Light energy is converted to chemical energy.

300

When plants die, they go to the soil to be decomposed and over millions of years are made into ______ .

What is fossil fuels (coal, oil, etc)?

300

What are the products of cellular respiration?

What is water (H20), Carbon Dioxide (CO2), and ATP (energy)?

300

Why is decomposition important in ecosystems?

It recycles nutrients back into the soil and supports plant growth.

300

How does burning fossil fuels disrupt the natural balance of the carbon cycle?

Burning fossil fuels releases large amounts of stored carbon dioxide (CO2CO_2CO2) into the atmosphere, which was previously sequestered underground for millions of years. This increases the concentration of greenhouse gases, leading to global warming and climate change, while also disrupting the natural balance of carbon absorption and release in ecosystems.

This organelle helps in the process of Photosynthesis.
What is the chloroplast?
400
The glucose made by plants is used by ________ .
What is all living things?
400

What do Cellular Respiration and Combustion have in common?

What is CO2? They both release CO2 to the atmosphere?

400

 How is carbon stored in the biosphere?

In the bodies of living organisms (biomass) and in organic material like soil.

400

Describe three ways that human are contributing to climate change

Burning Fossil Fuels

Deforestation

Agriculture and Livestock Farming

500

Write the chemical equation for photosynthesis.

What is 6CO2+6H2O+light→C6H12O6+6O2.

500

What factors affect the rate of photosynthesis

Sunlight, water and Co2

500

Describe the relationship between cellular respiration and photosynthesis?

Opposite Reactions:

  • Photosynthesis converts carbon dioxide (CO2CO_2CO2) and water (H2OH_2OH2O) into glucose (C6H12O6C_6H_{12}O_6C6H12O6) and oxygen (O2O_2O2), using sunlight energy.
  • Cellular respiration breaks down glucose and oxygen to release energy in the form of ATP, producing carbon dioxide and water as byproducts
500

How is cutting trees different than burning them down?

When trees are cut, they no longer absorb carbon dioxide (CO2CO_2CO2), but the carbon stored in their biomass remains sequestered until the wood decomposes or is burned.Burning trees releases stored carbon immediately into the atmosphere as CO2CO_2CO2 and other greenhouse gases like methane (CH4CH_4CH4).
