Randomly distribute the cards face down to students. Not to worry if there are not enough, tell students without cards that they will function as directors of dramatic play. When you call a symbol, the actors with those cards are to come onstage to the front of the room ans stand side by sideholding up their cards. I decompose everything left over when it dies in this food chain. I recycle nutrients and minerals so more green plants can grow for other food chains.
Most food chains begin with green plants which use solar energy to produce food.
Therefore, green plants are known as producers. Animals may eat green plants and be primary consumers, or eat other animals and be secondary consumers. Decomposers such as bacteria and fungi serve as recyclers of nutrients and energy from dead members of food chains. Food webs are derived by linkages of food chains. A change within the population of plants or animals will affect other organisms of the chain and its web.
