Practise describing biological trends from tables by identifying increases, decreases, maxima and minima, then supporting each conclusion with comparative data and units.
Acid rain has negative effects on many ecosystems.
One group of students recorded the change in temperature as the seeds germinated in five insulated flasks, labelled A to E.
Describe the results obtained by group 1.
germination / temperature, increased as, pH increased / acidity decreased ; ora no / little, effect / AW, at less than pH 4 ; ora
comparative data quote between pH and temperature with units stated at least once ;
I ref to pH 7.0 as optimum
