Answer:
1) The ecosystem would have the abiotic factors of low precipitation, dry winds, and low temperatures. The biotic factors would include the animals living with the penguins such as polar bears and yaks.
2) The population would suddenly increase if either the penguin's predators had a drop in numbers or if the penguin's food source became more readily available. This growth in population would result in food becoming harder to find and predators once again growing in numbers. This would eventually cause the penguin population to shrink once more.
3) Predators would die out. Whatever organism(s) were the penguin's food source would grow in size exponentially. Other animals may suffer a drop in numbers if the penguin's predators choose to prey on them.
C) Primary Producer. The producers are what make the food chain. Without them there would be no primary consumers. And without primary consumers there would be no secondary consumers.

Answer:
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.
