Question

after the devastating tsunami in japan in 2011, the fukushima nuclear power plant failed and released radioactive material into the ocean. which long - term impacts would radioactive material most likely have on fish populations?
exposure to radiation would result in a large fish kill, decrease reproduction rates for fish, and decrease the amount of fish caught by the industry.
exposure to radiation would result in a large fish kill, which would increase reproduction rates for fish and not impact the amount of fish caught by the industry.
exposure to radiation would result in a small fish kill, which would decrease reproduction rates for fish but increase the amount of fish caught by the industry and the food supply for the general population.
exposure to radiation would only result in water pollution, which would impact reproduction rates for fish and would increase the amount of fish caught by the industry.

Explanation:

Radiation is harmful to living organisms. It can cause death, and also negatively affect reproductive - related functions. A large fish kill would occur due to radiation exposure, and the radiation would also decrease reproduction rates. With fewer fish available overall, the amount of fish caught by the industry would decrease.

Answer:

Exposure to radiation would result in a large fish kill, decrease reproduction rates for fish, and decrease the amount of fish caught by the industry.
