B7: Quiz 9 – Answers
1)
i) Photosynthesis
ii) carbon dioxide + water –> glucose + oxygen
iii) Plants
iv) The carbon becomes carbon compounds in the plant (you could also say that some of the carbon is released back into the atmosphere through respiration)
2)
i) Respiration
ii) glucose + oxygen –> carbon dioxide + water
3) The process is called decay, which is where microorganisms and detritus feeders breakdown dead plant and animal matter. Whilst they are breaking down the dead plant and animal matter they respire, which releases carbon dioxide into the atmosphere (the equation for respiration is; glucose + oxygen –> carbon dioxide + water)
b) Waste products like faces and urine/ urea
4)
a) Combustion/ burning
b) Coal, oil and natural gas
5) When the giraffe eats the leaves on the tree, carbon goes from the tree to the giraffe
6) True
7) Leather or wool
8)
a) Warm
b) Moist
c) Lots of oxygen

Here is a partially completed carbon cycle to help you answer all of the questions in this section.
1)
i) What is the name of the process that takes carbon dioxide out of the atmosphere?
ii) Write the word equation for this process.
iii) Which type of organism carries out this process?
iv) What happens to the carbon that is taken in from the air during this process?
2)
i) Carbon can be released into the atmosphere when animals and plants undertake a process beginning with R; what is the name of this process?
ii) Write the word equation for this process.
3)
a) Give the name of the process and explain how carbon is returned to the atmosphere from dead plants and animals.
b) In addition to dead plants and animals, what other substance does the process outlined in part a deal with?
4)
a) What is the name of process A on the diagram at the top?
b) Give the 3 different fossil fuels.
5) A giraffe eats the leaves of a tree. Talk about what happens to the carbon during this process.
6) Is the following statement true or false
“volcanic eruptions can release carbon dioxide into the atmosphere”
7) Whenever we make products out of animals or plants, the carbon is stored in the products that we make. Give a substance from animals that contains carbon and can be used to create useful products.
