Question
What is a consequence of a global temperature rise on arctic ecosystems?
A. Decrease in CO2 released from decomposing detritus
B. Increase in the greenhouse effect
C. Decrease in ocean level
D. Increase in pest species
Markscheme
D
Examiners report
There were some issues in this question regarding the possibility that answer B is also correct. Although many candidates did go for B, D is a better answer as what is asked for is the consequence, not the cause for the greenhouse effect.
