1. Here are three food chains:• A grass rabbit fox• B wheat field mouse fox• C wheat field mouse grass snake1 Sketch a pyramid of numbers for food chain A.2 Use all three food chains to draw a food web.3 Name one producer in the food web. 4 Name a primary consumer. 5 Name a secondary consumer. a If the field mice died, what would happen to the

number of grass snakes?b Why would this happen?c If the field mice died, what might happen to the

number of rabbits?d Why might this happen?
