Zebra mussels feed on phytoplankton, which zooplankton need as a food source.
Explanation:
The population of zooplankton in Lake Erie and the Hudson River declined due to the arrival of zebra mussels because Zebra mussels feed on phytoplankton, which is the main source food of zooplankton. So due to limited or scarcity of food in the environment, the zooplankton die due to hunger that leads to the decrease of population of zooplankton in that environment.

Answer:
Genotype: all Bb
Phenotype: all purple
Explanation:
Blue color chromocat will have the genotype BB.
Red color chromocat will have the genotype bb.
If the two are crossed:
BB   x   bb = Bb, Bb, Bb and Bb
All the offspring will have a genotype of Bb.
A genotype of Bb has a phenotype color of purple.
Hence:
<em>The genotype of all the offspring will be Bb.</em>
<em>The phenotype of all the offspring will be purple.</em>
