A massive bluegill fish kill was observed in a lake near a power plant during the winter months. It was determined that the plan
t was releasing large amounts of hot water into the lake. Which of the following explains what likely caused the death of so many bluegills in the lake? A: The increased water temperature caused dissolved oxygen levels to increase, leading to greater metabolic activity of catfish, which outcompeted the bluegill fish for resources.
B: The influx of warmer water caused an unexpected increase in the metabolic rate of the bluegills, which led to increased physiological stress from limited resource availability.
C: Rates of organic matter decomposition increased, which lead to an increase in dissolved oxygen and increased bacteria levels.
D: Photosynthetic output of aquatic plants decreased because of the higher temperature, which lowered the amount of carbon dioxide available for bluegills to carry out cellular respiration.
Without this information the virus would not be contained, we would not have done research, taken samples, tested out the virus, or even attempted to contain it. With this information we can attempt to prevent a break out of the disease again. This is my personal opinion though.
In an experiment, using the elodea stalk, you are able to expose more underlying tissue and the process can be executed more quickly and it's easy to replicate the natural position for a more realistic result. hope this helps
The answer is D matter and energy shown in the question can change forms and is transferred to other locations for organisms to be used as building blocks for others.<span />
