Question

Meg drew this model to show the carbon cycle. However, there are errors in her model. Which arrows point in the wrong direction?

Answer 1

The right answer are C and D.

The cellular respiration of plants takes place in the same way in animals, so there is CO2 emission and so the arrow has to be directed to the outside.

Industrialists participate in more than half of greenhouse gas emissions. The factories emit gaseous products (among others CO2) So the arrow must be directed to the outside.

Energy production, industry and construction account for 56% of carbon dioxide (CO2) emissions, responsible for global warming

Answer 2

Factory Emissions is going in the wrong direction. The arrow should be pointing upward, as factory emissions release carbon into the atmosphere.
