Ecology Review

What is your name? Be sure to include your first and last name so that you get credit. Matching Match the term with its definition. Food Chain Shows how energy flows in an ecosystem Food Web Shows several connected food chains Energy Pyramid Shows the amount of food energy available at each level of a community. Ecosystem All living and nonliving things in one place Population Made up of the members of one species that live in an area Community All the populations in an ecosystem at the same time Identify the choices below as either a biotic factor or an abiotic factor. Biotic Factor Animals Plants Fungi Bacteria Abiotic Factor Water Light Rocks Soil Wind Temperature Use the word bank to complete the sentences below: A producer is an organism at the beginning of a food chain because they can produce their own food using energy from the sun.2. Organisms that feed off of other organisms and cannot make their own are known as a carnivore.3. A nonliving part of the environment is a(n) abiotic factor.4. A living part of the environment is a(n) biotic factor.5. A consumer that eats only plants is known as a herbivore.6. A consumer that eats both plants and animals is called a(n)omnivore.7. Energy is transferred through an ecosystem by eating or consuming food and is represented on food chains and food webs using arrows.8. Decomposers breakdown decaying organisms and nutrients are put back into the soil by bacteria and fungi. Use the following food web to answer the questions below: - The arrows represent energy.- In this food chain, which organism is the producer? grass- In this food chain, which organism is the primary consumer? grasshopper- In this food chain, which organism is the tertiary consumer? snake- In this food chain, which organism is an herbivore? grasshopper- What type of consumers are the frog and the snake? carnivores- If the frog population increased, what would happen to the grasshopper population? It would decrease.- If the frog population increased, what would happen to the snake population? It would increase.- Which organism has the highest amount of energy? grass- Which organism has the lowest amount of energy? snake- What was the original source of energy in this food web? The sun Use the food web below to answer the following questions What level of consumer is a wild cat? Primary Consumer Secondary Consumer Tertiary Consumer Producer What level of consumer is a goat? Primary Consumer Secondary Consumer Tertiary Consumer Producer Which organism is the producer? Owl Snake Kite Tree This food chain can be found in the coastal waters of Virginia. The population of which organisms in the food chain would be the first to decline if commercial fishing over-harvested shrimp? Algae Zooplankton Damselfish Barracuda The Flow of Energy in a Food Web Click on the blue circles and fill in the missing information with the role each plays in the food web. (Use one of the following words: herbivore, omnivore, carnivore, decomposer.) DO NOT use capital letters. herbivore carnivore carnivore decomposer What is my Role? Use the picture of the food web to sort the following organisms.For each organism, decide what role it plays in the food web. Click on the organism and then select the correct category. Omnivore Humans Eats both plants and animals Carnivore Killer Whale Penguin Leopard Seal Elephant Seal Meat eaters Herbivore Krill Cod Zooplankton Eats only plants Producer Phytoplankton Make their own food Label Each Level of the Energy Pyramid. DO NOT USE CAPITAL LETTERSWORD BANK: secondary consumers, primary consumers, producers, tertiary consumers tertiary consumers secondary consumers primary consumers producers Using the Energy Pyramid above, which level contains the most stored energy? Primary Consumers Tertiary Consumers Secondary Consumers Producers Using the Energy Pyramid above, which level is made up of HERBIVORES? Producers Primary Consumers Secondary Consumers Tertiary Consumers How much energy is transferred from one level to the next? 5% 20% 10% 90% Food Web Draw arrows to connect the food web and show the flow of energy through the ecosystem. Producer or Consumer? Identify the choices below as either a producer or a consumer. Producer Grass Moss Trees Water Lilly Vegetables Flowers Consumer Cow Dog Grasshopper Hawk Rabbit Fish Changes in an Ecosystem - How Can They Affect Food Webs? Using the food chain below. Describe how the other populations in the food chain would be affected if the population of grass decreased.Use complete sentences and proper grammar Changes in an Ecosystem - How Can They Affect Food Webs? Using the food chain below. Describe how the other populations in the food chain would be affected if the population of fox increased. Use complete sentences and proper grammar Decomposers. Why are they important? What is a decomposer and why are they important? What do you think Earth would look like if we did not have decomposers?
