Before you begin your lab, write a hypothesis that reflects how you think temperature of the water will affect the reaction rates. Record your hypothesis as an "if, then" statement.

The temperature of the water has important  role in the  reaction rates.

A hypothesis is a prediction made before any experiment or study that shows  relationship between a dependent variable and independent variable.

A hypothesis before begin a lab is "If the temperature of water will rise, then the rate of reaction will be high".

youre right there are

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
