Free Energy Homework 1

Part One: IDENTIFICATIONS (IDs). Use the book to help you identify the following. Be as specific as possible, and include names, dates, and relevant facts as appropriate. Be sure to explain the significance of the term.There should be a minimum of three (3) sentences for each ID. Use of the internet is okay if you are stuck, as long as you do not plagiarize.

Part Two: Rule of 10 Problems. Complete the problems using the Rule of 10 (Energy) in class. Use the food chain below to help you answer the problems.

1) If you started with 200,000 Calories of energy at the producer trophic level of this food chain, how much energy would be available to the other levels of the food chain?

2) Hunting of owls became legal in this ecosystem. Describe the changes that would occur to each trophic level because of this action.

Part Three: Types of Photosynthesis, an Evolutionary Advancement. Complete the questions using your book, starting on page 195.

A) Type 1: C3 plants Page 195

How does it work?

Examples of C3 Plants:

What is photorespiration?

B) Type 2: C4 Plants Page 196

Why is this process named C4?

Examples of C4 plants:

How does this process work?

Why is this such a great adaptation?

C) Type 3: CAM Plants Page 196

Examples of CAM plants:

How does this process work?

How do C4 and CAM photosynthesis differ?

Part Four: Critical Thinking

3) The diagram below shows an experiment that took place with chloroplasts. The chloroplasts were first made acidic by soaking them in a solution at pH 4. After the thylakoid space reached pH 4, the chloroplasts were transferred to a basic solution at pH 8. The chloroplasts then made ATP in the dark. Explain this result.
