 *  a.  ****Create as many food chains as you can form the list of plants and animals: **
 *  b.  ****Create a food web using the food chains(start with producers and work upwards and make sure your arrows point in the right way) **

Plants are producers ** d.  ****Identify each food web as first, second, or third order **  1. Butterflies are first order consumer which eat plants  2. Feral cats are second order consumers because they eat animals which eat plants  3. Snakes are third order consumer because they eat animals which eat animals which eat plants
 *  c.  ****Which organisms are producer? **
