Answer:
Power output, P = 2 watts
Explanation:
It is given that,
Work done by a horse, W = 860 J
Time taken, t = 420 seconds
We need to find the power output of the horse. Power output is given by work done divided by total time taken i.e.
P = 2.04 watts
or
P = 2 watts
So, the power output of the horse is 2 watts. Hence, this is the required solution.

Question:
Solution (explanation):
Within an ecosystem, we can find photosynthetic organisms such as plants. The general chemical reaction for photosynthesis is 6 carbon dioxide molecules and 6 water molecules, with the addition of solar energy. This produces 1 glucose molecule and 6 oxygen molecules. Therefore, if one of the reactants of the photosynthetic reaction, namely carbon dioxide, decreases, the amount of glucose (energy storage molecules) will decrease. Remember that energy storage molecules include glucose, starch, and fat.
Answer: we can conclude that the correct answer is:
Decrease in energy storage molecules.
