(a)

Summary Introduction

To determine: The cause for formation of epilimnion, hypolimnion, and thermolimnion.

Introduction:

The lake is stratified into three layers epilimnion, hypolimnion, and thermolimnion. Epilimnion is the topmost layer of the lake. Thermolimnion is the middle layer; the depth of the thermolimnion is different during different times in a day. Hypolimnion is the lowermost layer in lake.

Summary Introduction

To determine: The reason why most of the fisheries live in regions where the three stratified layers are mixed with each other continuously by strong waves.

Introduction:

The lake is stratified into three layers on the basis of temperature difference epilimnion, hypolimnion, and thermolimnion. Epilimnion is the topmost layer of the lake. Thermolimnion is the middle layer and Hypolimnion is the lowermost layer in lake.

(b)

Summary Introduction

To determine: The microbial process that occurred in Lake Erie.

Introduction:

Algae are the photosynthetic microorganisms that utilize the sunlight to synthesize their own food. There are three types of pigments present in algae chlorophyll, carotenoids, and phycobilins.

Summary Introduction

To determine: The geochemical cycle involved and how the lake was brought back to life.

Introduction:

Algae are the photosynthetic microorganisms that utilize the sunlight to synthesize their own food. The algae are divided into different types based on their color such as red algae blue algae, yellow algae and green algae based on the type of pigments present. When the algae show overgrowth due to extra presence of nutrients it is called as algal bloom.
