Answer;
B. Increased levels of carbon dioxide, a greenhouse gas, leads to increased phytoplankton growth.
Explanation;
-A combination of warm water, high nutrient levels, and adequate sunlight may cause a harmful algae bloom. These blooms may damage aquatic ecosystems by blocking sunlight and depleting oxygen that other organisms need to survive.
-Algae blooms have been increasing globally, and climate change may be playing a role in the increment. For instance, during the warm summer season or when water is warmer, some harmful types of algae to grow faster than other, more benign varieties.
-Additionally, the warmer surface water also prevents water from mixing vertically, allowing algae to grow thicker and faster.

The change in internal energy of the gas is -9 J
Explanation:
First of all, we need to calculate the amount of work done by the gas. This is given by the equation:
where
is the gas pressure
is the final volume of the gas
is the initial volume of the gas
Substituting, we find:
Now we can apply the 1st law of thermodynamics to calculate the change in internal energy of the gas:
where
is the change in internal energy of the gas
Q = -45 J is the heat released by the gas (negative because it is given off bu the system)
W = -36 J is the work done by the gas (negative because it is done by the surrounding on the gas)
Substituting, we find:
