c. scavengers. For example, we cannot live strictly on sugar, despite its high caloric content, irrespective of what our kids may argue. I will illustrate some aspects of lake food-web structure with examples from Lake Constance, which food web has been rather well studied during recent years (see Box 4.1). d. a population chart. Primary Consumers. Answer these questions about the food web above. The concept of a food web is credited to Charles Elton, who introduced it in his 1927 book, Animal Ecology. These complex diagrams often appear as intricate spider webs connecting the species. A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). a. energy pyramid c. food web b. food chain d. ecosystem chart ____ 11. c. a food chain. Evaluating the food webs will determine if the students were able to organize the plants and ... Take a field trip to a pond or lake in your community. Food web diagrams depict all feeding interactions among species in real communities. The simple diagram of the Ecological Pyramid Food Web and Food Chain is shown below. You can edit this Spider Diagram using Creately diagramming tool and include in your report/presentation/website. b. a food web. Great Lakes Food Web Diagrams Great Lakes Environmental Research Laboratory (GLERL) has recently developed food web diagrams for all of the Great Lakes and Lake St. Clair. webs’’). Sometimes, these primary consumers become prey for other animals that sit higher on the food chain. ____ 12. While a food chain shows how ecosystems function in a linear way, a food web is a more visual approach with multiple animals connected to one another. Food webs may be described in terms of both energy and nutrient (carbon, nitrogen or phosphorus) flows (Figure 15).Although the process typically begins with sunlight-driven photosynthesis by algae and plants, balanced nutrition is also required to sustain life. David J. Kelly, Marc Schallenberg, Assessing food web structure in relation to nutrient enrichment, macrophyte collapse and lake resilience in shallow lowland lakes, New Zealand Journal of Marine and Freshwater Research, 10.1080/00288330.2019.1606021, (1-17), (2019). The interconnectedness of how organisms are involved in energy transfer within an ecosystem is vital to understanding food webs and how they apply to real … Take the water samples back to the classroom and ... See food web diagram for answers 3. A Spider Diagram showing Lake Tahoe food web. Creating a food web is a really great way to learn more about how organisms and animals live in their natural habitats. This process diagram by Peter Lee displays the food web at Mono Lake. Algae are the primary producers, that is, they are able to convert light, nutrients, minerals, … A food web can be described as a "who eats whom" diagram that shows the complex feeding relationships in an ecosystem. A simple diagram with arrows showing a single pathway of energy flow from grass, to a rabbit, to a fox is a. an energy pyramid. This lesson demonstrates that changes in one part of a food chain or web may affect other parts, resulting in impacts on carnivores, herbivores, and eventually on producers. Herbivores, carnivores, and omnivores are all a. decomposers. They are also called herbivores animals who eat producers or plants. Figure 14. mono lake food web. The major species in each lake are briefly described, along with a diagram summarizing the ecosystem energy flow (who eats or is eaten by whom! In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4). A simple introduction to the idea of a lake’s food web is to think of it simply as bigger fish eat smaller fish that eat the small floating critters that eat algae, as in the first diagram. ).
