carbonate cycle, respiration and photosynthesis

carbonate cycle, respiration and photosynthesis

course plus quiz

after an explanation, you have a little quiz to know if you understand or no

photosynthesis

It's use: gas ( CO2) + water (H2O) + sunlight (energy) ---------- to make food ( C6H12 O6) + oxygen ( O2).

only producers can make a photosynthesis.

Producer use the sugar making by producers to feed them self.

The living things who can make their own food are called..................( producer \ consumers)

They constitute ( autotrophs\ hétérotrophs)

Multiple Choice

plants are considered like...

• heterotrophs

• autotrophs

Multiple Choice

In what process is Carbon transformed into chemical energy?

• photosynthesis

• respiration

• primary producer

• secondary producer

Multiple Choice

How does the carbon in grass become part of a lion?

• the lion eat the grass

• The carbon ends up in the lion's food chain.

• The lion breathes in carbon given out by the plant

• Carbon from grass doesn't end up in a lion.

Multiple Choice

What does not produce carbon dioxide?

• animals respiration

• photosynthesis

• Burning Fossil Fuels

• Plants decaying

respiration

respiration use oxygen ( O2) + sugar or food ( C6H12O6) to produce gas ( CO2) and Water + energy

The energy making by respiration help the livings things to move, walk, enjoy...etc.

if only producers do a photosynthesis, producers and consumers can do the respiration.

The plants are special because they can do photosynthesis( in the day) and respiration( in the night).

what's products coming from respiration?

respiration produce are: gas (CO2) , oxygen (O2) and energy.

Nutrients are all chemicals elements required for life.

For example: carbonate, oxygen, hydrogen, nitrogen, calcium...etc

respiration use the energy store to produce elements, but photosynthesis use the sunlight to store energy (sugar) .

Multiple Choice

Which one of these does not add CO2 to the atmosphere?

• cooking with gas

• burning wood

• planting trees

• riding in a bus

Multiple Choice

In the carbon cycle, producers take in the gas __

• carbon dioxide

• oxygen

• nitrogen

• carbon monoxide

Multiple Choice

Which of the following adds oxygen to the atmosphere?

• respiration

• photosynthesis

• Forest fires

• Life processes of animals

decomposers

decomposers are living things who use the waste or corpses to making return carbon in the atmosphere.

They change the waste things in nutrient , using by plants to make their foods.

decomposers are: saprotrophs and detritivores.

the decomposers product going to the soil.

example of decomposers: worn, bacteria, cyanobacteria

combustion is another word to said burning.

Multiple Choice

How do living organisms return carbon to the atmosphere in the carbon cycle?

• respiration and photosynthesis

• decomposition and respiration

• combustion

• fermentation

Multiple Choice

Why is the carbon cycle important?

• It helps animals to digest food

• It takes nitrogen and oxygen out of the atmosphere

• It continuously reuses and recycles carbon in the ecosystem

• helps human to do a photosynthesis

Multiple Choice

In the food web, which organisms release the carbon from dead things back into the environment?

• heterotrophs

• producers

• consumers

• Decomposers

• autotrophs

Multiple Select

Carbon is stored in

• ocean

• Trees and other living things

• Underground in soil and fossil fuels

• All are correct
