Q1. Suppose that a deep temperate zone lake did not "turn over" during the spring and fall seasons. Based on the physical and biological properties of limnetic ecosystems, what would be the dissimilarity from normal seasonal turnover?
Lakes would suffer a nutrient depletion in surface layers.
The pH of lake would become increasingly alkaline.
The lake would fail to freeze over in winter.
An algal bloom of algae will result every spring.
The lake would be uniformly cold during the winter and summer.
Q2. Evaluate the sizes of the different digestive organs in the earthworm. Which organ is the main? How does its size make it well suited for its function?
