Answer:
reflect the conditions and changes of an environment where they live.
Explanation:
Effective indicator species need distinct environmental factors to sustain and survive in the environment. They reflect the conditions and changes of an environment where they live.
Fishes, specifically steelhead trouts, are an effective indicator species because steelhead trouts require distinct environmental conditions to survive such as temperature of the water, availability of food, specific waterbed, etc. If there is an absence of steelhead trouts in a particular body of water, scientists can easily determine that the water has environmental problems.

The direct and easy solution for this problem is through dimensional analysis. This is done by cancelling out the same units of dimensions resulting to the unit of what is asked. In this case, the resulting unit should be in $.
The number of hours in a day from 7:15 am to 2:45 pm is 7.5 h. In 187 days, that would be:
187 days * 7.5 h/day = 1402.5 h
The rest of the solution goes:
1402.5 h * $0.1/kWh * 1 kW/1000 W * 35 W/bulb * 72 bulbs =
$353.43
