Question

Example #1: Each of the graphs below represents a potential relationship between two environmental variables. The graphs are used in questions 1-4, and each graph type may be used more than once. For each pair of x and y variables, select the graph (A, B, C or D) which best describes the relationship between x and y.

x-axis; y-axis

1._____environmental temperature; body temperature of an endotherm

2._____environmental temperature; body temperature of an ectotherm

3._____soil moisture from very dry to very wet; performance (growth, reproduction, survival) of a temperature forest plant

4._____salinity (salt content, ppt); water density (kg/m^3)

**Answer is 1. Graph B, 2. Graph C, 3. Graph D, 4. Graph C I just need an explanation, please!

Explanation / Answer

1. Graph B represents the environmental temperature; body temperature of an endotherm

2. Graph C represents the environmental temperature; body temperature of an ectotherm

3. Graph D represents salinity;water density

4. Graph A represents soil moisture from very dry to very wet; performance of a temperature forest plant.
