Worked Solution & Example Answer:The graph shows information about four species of bacteria and their reproductive rates at different temperatures - HSC - SSCE Biology - Question 3 - 2002 - Paper 1
Step 1
What conclusion can be drawn from this graph?
Answer
From the graph, it is evident that each species of bacteria has a specific reproductive rate that varies with temperature. Notably, each species has an optimal temperature range for reproduction, and they do not share a broad temperature adaptability.
The graph suggests that:
- Species W shows optimal reproduction at low temperatures.
- Species X has a moderate range with a peak production around the middle range.
- Species Y and Species Z demonstrate that each has a defined peak and drop-off at higher temperatures.
Thus, the best conclusion is (D): Individual species reproduce in a relatively narrow range of temperatures. This conclusion aligns with the graphical representation, indicating each species thrives in specific thermal conditions, highlighting their limitations to broader environmental factors.
