by decreasing the amount of salt dissolved in ocean water by increasing the water's ability to separate into distinct layers by changing temperature conditions that single-celled producers require by preventing organisms from responding quickly to environmental change
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: Climate change may be reducing the amount of ice floating on the world's oceans. How can this change most likely alter the food supply available to marine consumer organisms?
Possibilities:
- by decreasing the amount of salt dissolved in ocean water
- by increasing the water's ability to separate into distinct layers
- by changing temperature conditions that single-celled producers require
- by preventing organisms from responding quickly to environmental change
