Food Web Worksheet. Part A: Use the marine food chain below to answer questions 1 to 5. 1. Identify the organism (s) that are producers. Phytoplankton (underwater microorganism which produces glucose by photosynthesis...so a plant more or less!) 2. Identify the organism (s) that are consumers. Zooplankton, Small Fish, Big Fish, Mammal. 3.
Select four cards to create a food chain, starting with a producer. Label the trophic level of each organism in your food chain as follows: producer, primary consumer, secondary consumer, tertiary consumer. Record your food chain in the space below using species names and arrows.
Food chains "end" with top predators, animals that have little or nö natural enemies. When any organism dies, it is eventually eaten by detrivores (like vultures, worms and crabs) and broken down by decomposers (mostly bactejia and fungi), and the exchange of energy continues.
ANSWER KEY. Label each organism based on its position in the food web: = Producer, 1 = Primary Consumer, Then label each animal as: H = Herbivore, 2 = Secondary Consumer, 3 = Tertiary Consumer, D = Decomposer (Some may have more than one label.) C = Carnivore or O = Omnivore. P. 1, H 3, C. Oak Tree.
ANSWER KEY. Food Web. A food web shows how energy is passed on from one living thing to the next. It shows the feeding habits of different animals that live together in an ecosystem. In the food web pictured on the left, energy is passed from the grass to the mouse to the snake to the hawk.
In this worksheet, we will practice interpreting the interdependent relationships of organisms in ecosystems using food webs. Q1: Each link of the food chain is named according to what the organism eats and how it contributes to the energy of the ecosystem.
Food chains and food webs can both be used to show how energy moves from the sun to different animals. A food chain shows the path of energy through a chain of different organisms.
