The type of fish in the pond this year tended to be smaller than the type of fish last year

There was less food available in the pond this year than last year

There were fewer fish year than there were last year

Answer 1

The statement that best explains the observation that the fish are smaller than they had been the previous year is:

There was less food available in the pond this year than last year.

This is because if there is less food, the fish may not receive adequate nutrition to grow to their full size, resulting in smaller fish overall.
