The ecosystem consists of interaction between species and abiotic factors. The environment is made of two types of factors: biotic factors which include living organism and an abiotic factor which includes nonliving things.

Summary Introduction

To explain:

The ways in which gopher and mole compete for food.

Introduction:

The place where species can get food and fulfill their needs is called habitat. According to competitive exclusion principle, two species cannon coexist in the same habitat. In this case, species need to compete with other for food.

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain. Why does changing the pH affect the enzyme activity? Research the enzyme catalase. What is its function in the human body? What is the optimal pH for the following enzymes found in the human body? Explain. (catalase, lipase (in your stomach),…
