Food Chains & Food Webs

Master food chains, food webs, and energy flow! Identify producers, consumers, and trophic levels.

What is the difference between a food chain and food web? Food webs only follow just one path as animals find food A food chain shows the many different paths that energy flows through many plants and animals. A food chain only follows just one path as animals find food A food web shows the many different paths that energy flows through many plants and animals. A food chain consists of many food webs. A food chain only follows just one path as animals find food. Identify the choices below as either a producer (which produces its own food) or a consumer (which takes in other organisms for energy). Producer Moss Trees Grass Flowers Water Lilly Vegetables Consumer Dog Hawk Cow Fish Grasshopper Rabbit Food Web - use the food web to answer the next several questions. Looking at the food web above, what eats the grass? the snake the mouse and the grasshopper the ant and the frog the grasshopper and the ant Looking at the food web above, what does the eagle eat? snake only snake and mouse mouse only mouse and grasshopper Looking at the food web above, determine the tropic level of each organism. Click on the table and chose the correct option. Organism In Food Web Trophic Level Eagle Quaternary and Tertiary Consumer Snake Tertiary Consumer Mouse Secondary Consumer Frog Secondary Consumer Grasshopper Primary Consumer Ant Primary Consumer Grass Primary Producer The flow of energy through a food energy. Only 10% of the energy is passed on and the rest is lost as heat or used by the organism for everyday tasks (breathing, heart beating, walking, hunting, repairing cells, etc.); To calculate the amount of energy passed on just to the next organisms, just multiply by 10 and then divide by 100. Pond Food Chain Energy Flow Click on each organism from the pond food chain and label it with the amount of energy it has. The rule is, is that it only passes on 10%. So multiply by 10 then divide by 100! The plant will start at 100,000 units of energy do the math to figure out the rest. HINT: Be sure to include a comma if a number could use one. 100,000 10,000 1,000 100 10 1
