Today we'll be working on the ecosystems powerpoint from last lesson (the post below this one), and completing these questions in your books if you've already done the assignment:

1. Define sexual and asexual reproduction.
2. Using the link from question 1, what type of reproduction leads to variation in a population?
3. What does DNA in genes code for?
4. Use the image to place the following in order from smallest to largest - Nucelus, DNA, chromosome, gene.                                   
5. Apart from genetics, what else can influence how an organism looks?
6. Briefly describe what cloning is and outline one way that it can occur:
7. Play this game, what things are randomly separated to determine what the offspring will look like?

Try any of these once you're finished.

Assignment 1 - Ecosystems

Today you need to make sure you've finished the first assignment and put everything in your red folder, so Mr. Cole can mark it for you. That means you need:

• 2 keys (one for snakes, one for plants).
• The answers to the questions from the post below this one.

1.  For the next part of the assignment, you will need to create a powerpoint.  List the 5 kingdoms of living things , with one on each slide. Make sure you give two examples of each kingdom, and a picture or drawing of them.

2. You also need to explain the difference between invertebrates and vertebrates.  This should be about two sentences of writing, giving an example of each.

3. Finally, list the five classes of vertebrates here and give three features of each of them.

Save your work as you are doing it, and check with Mr. Cole before you print anything off. 

Classification of organisms

Today we're going to look at classification of living things into different groups. Answer the following in your books:
1. Why is classification in Biology important?
2. Give one feature that each group in this image. Include your answer in a table, and use this link to help you.
 
3. Use the link here to write down a fact about one animal you find.
 Complete this activity, then answer the following questions about it.
4. What is an omnivore?
5. What will happen if there are no frogs in the food chain?
6. What organism is the producer in the northern food chain?
7. Complete this activity, and explain what decomposers do in a food chain.
