Drag and drop to match the source with the correct fuel

Which of the following is the correct word equation for aerobic respiration?

Fill in the blanks with one of the following words to match the factor with its effect on the amount of carbon dioxide in the atmosphere:

Increases, decreases

Carbon dioxide dissolving into the oceans = the amount of carbon dioxide
Volcanism = the amount of carbon dioxide
Photosynthesis = the amount of carbon dioxide

[question number = 07.4] When fossil fuels are burned they release carbon into the atmosphere – which of the following are fossil fuels?

[question number = 07.5] Decomposers break down dead animal and plant material – what happens to the carbon inside the dead organisms?

All of the carbon is released during respiration
All of the carbon becomes part of the decomposers
Part of the carbon is released during respiration and part is stored in the decomposers cells
Most of the carbon is destroyed and no longer exists

Respiration from animals is a source of carbon dioxide in the atmosphere – do plants also use respiration?
