Question

PLEASE ANSWER 

Vocabulary: consumer, ecosystem, energy pyramid, equilibrium, food chain, population, predator, prey, producer Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The Food Chain Gizmo shows a food chain with hawks, snakes, rabbits, and grass. In this simulation, the hawks eat snakes, the snakes eat rabbits, and the rabbits eat grass. 1. Producers are organisms that do not need to eat other organisms to obtain energy. A Which organism is a producer in this food chain? B. Where does the producer get its energy? 2. Consumers must eat other organisms for energy. Which organisms are consumers in this food chain? Gizmo Warm-up The SIMULATION pane of the Gizmo shows the current population, or number, of each organism in the food chain. MOVE HAWKS ADDREMOVE 1. What are the current populations of each organism? Snakes: Grass: Hawks: Rabbits: 2079 2. Select the BAR CHART tab, and click Play (). What do you notice about each population as time goes by? If populations don't change very much over time, the ecosystem is in equilibrium. 3. Notice the populations decrease as you go from the bottom of the food chain to the top. Why do you think this is so? This diagram, showing decreasing populations at each level, is called an energy pyramid.
