Task: At this station, you will analyze data to determine the
effect of thermal pollution on a certain species of fish.
Background
Water temperature is a limiting factor in an aquatic habitat, affecting
activities such as respiration and reproduction.
Directions
Examine the data in the table below. It shows the concentration
of dissolved oxygen available in water at different temperatures.
The oxygen available to fish is in units marked ppm or "parts per
million." A higher ppm reading indicates a greater concentration
of oxygen.

- Construct a line graph of the data presented above.
- A certain species of fish normally live in a pond that never
exceeds the temperature of 10 degrees Celsius. this species of
fish requires a dissolved oxygen level 9.5 ppm. Industrial development
has the potential of increasing the pond's temperature by releasing
hot water produced during necessary process. Answer the questions
below based on your knowledge of biology and using your graph.
Scoring
