Students set up an experiment to investigate how temperature differences in water create currents. The students fill three identical tanks with the same amount of 20°c water. They put identical heaters in each tank. In the first tank, the heater is set to 20°c. in the second tank, the heater is set to 30°c. in the third tank, the heater is set to 40°c. The student then places drops of dye in the tanks to observe the water movement. What is the dependent variable in the experiment?

How does the quoll receive energy directly?
How does the quoll receive energy directly?
from the hopping mouse and the honeyeater
Describe how the honeyeater indirectly receives energy from the sun.
Describe how the honeyeater indirectly receives energy from the sun.
The wisteria transforms light enrgy into chemical energy and stores it. The honeyeater consumes the wisteria's extra chemical energy.
