- Name the trophic levels in an ecosystem and explain how energy moves through the trophic levels. Can you use the words food chain and food web in the discussion.arrow_forwardCompare how energy and matter flow in an ecosystem and relate this flow to the laws of thermodynamics and matter conservation.arrow_forwardDraw a diagram of the model you created that shows how energy flows through a food web Use arrows to show the energy path flowing from one organism to another. Include a legend to provide details about color representation. For example, the green lines show energy flowing from producers.arrow_forward
- Use the information and model to answer the following question. This model describes energy movement in an ecosystem. image What should be placed in box 5 to BEST complete the model? A. Autotrophs, because all food webs begin with autotrophs obtaining solar energy from the sun. B. Autotrophs, because all food webs in an ecosystem begin with autotrophs. C. Decomposers, because they are at the top of the food web and receive the most energy. D. Decomposers, because they break down organisms from all trophic levels to obtain energy.arrow_forwardWith the help of a diagram, represent the energy flow through different trophic level.arrow_forwardUse the information and diagram to answer the following question. The energy pyramid is a shape often used to describe and identify roles of organisms in an ecosystem. image Using the sections of the pyramid provided, which answer choice describes a relationship found in an ecosystem? A. II represents secondary consumer and III represents a tertiary consumer, which explains why the top of the pyramid is smaller than the base. B. IV represents producers and I represents primary consumers which explains why the base of the pyramid is the largest. C. IV represents the top predator and I represents the primary producers, which explains why the base of the pyramid is larger than the top. D. I represents a predator and II represents a prey which explains why the top of the pyramid is smaller than the base.arrow_forward
