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 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.
A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents.
7 kwi 2020 · The arrows in a food chain show the flow of energy, from the sun or hydrothermal vent to a top predator. As the energy flows from organism to organism, energy is lost at each step. A network of many food chains is called a food web.
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.
Ecological Pyramids Worksheet 1. Give one example of a food chain that exists in nature. 2. In an ecological pyramid, what happens to energy, biomass and # of species as you move up? Why? 3. What is biomass? 4. In an ecosystem, can there be more carnivores than herbivores? Explain why or why not? 5. What is the 10% rule? What is its significance?
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.
