Energy Transfer

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 Match Match the parts of the food chain. Producer Grass Primary Consumer Grasshopper Secondary Consumer Mouse Tertiary Consumer Snake Quaternary Consumer Hawk 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 divide by 10! The plant will start at 100,000 units of energy do the math to figure out the rest. 100,000 10,000 1,000 100 10 1 Answer the following questions using the pyramid below. Which trophic level has the most energy? 1st trophic level (producers) 2nd trophic level (primary consumers) 3rd trophic level (secondary consumers) all levels have the same amount of energy What happens to the amount of energy available to organisms when moving from trophic level 1 to trophic level 2? the energy increases by 90% the energy decreases by 10% the energy decreases by 90% the energy increases by 10% The picture below shows an energy pyramid.What will most likely happen to the foxes and the wolves if the rabbits are removed? The foxes will eat more wolves. The foxes will eat fewer wolves. There will be more foxes and wolves. There will be fewer foxes and wolves. Which statement best describes the flow of energy as it passes through the organisms in the pyramid? Energyflows through the organisms from bottom to top and increases at each level. Energyflows through the organisms from bottom to top and decreases at each level. Energyflows through the organisms from top to bottom and increases at each level. Energyflows through the organisms from top to bottom and decreases at each level. The diagram below shows a simple food web.Which animal is classified as an omnivore? red fox deer black bear rabbit The diagram below shows a simple food web.Which of the following animals might compete with the coyote in this food chain? Deer Rabbit Owl Canary
