Study the graph below. at what depth does the thermocline begin? a line graph relating ocean depth to water temperature. at 0 meters, temperature is approximately 27°c. at 100 meters, temperature is approximately 24°c. at 200 meters, temperature is approximately 11°c. at 300 meters, temperature is approximately 8°c.

The thermocline begins at 100 meters.

The thermocline in an aquatic ecosystem presents a layer of water which has a steep decline in temperature. In this layer, the temperature of the water drops much faster than in the layers above. This happens because this layer is a ''buffer'' zone between the warm water of the surface layers and the cold layers of the deep.
So, in this case, in the zone between 100 and 200  meters, there is a sharp decline from 24 degrees to 11 degrees.

False because when you are going on any water activities it is good to know if the water has any recreational illnesses its false on edgenuity also  

Yes yes yes very good
