There would be a reduction in surface nitrogen concentration, which would cause an algal bloom.
The remaining whales would accumulate mutations at a faster rate.
The surface fish populations would decline due to reduced populations of algae.
The remaining whales would be forced to foragein the deepest parts of the ocean.
​All of the following are primary functions of flowers except
pollen production
photosynthesis
egg production
meiosis
