Assignment 1 task 2

Today we're going to finish a part of assignment 1 that I wasn't aware we had to complete.
In a powerpoint, complete the following tasks:

1. Use this link to create a food web (different to a food chain).  Once you've done this, list at least three ways that the plants and animals need each other APART from for food. 
2. Explain how the population of a group of animals can change over time, depending on the numbers of other animals. Complete this in a few sentences on a separate slide.

CHECK YOUR WORK WITH MR. COLE BEFORE PRINTING IT.
