- Explain why there are differences in the efficiency of energy transfer between trophic levels. Explain what happens to the energy which is not transferred to the next trophic level in a food chain when one organism feeds on another.Explain how/why ecologists can use trophic cascades to understand the “bottom up” vs. “top down” dynamic of a systemDescribe feeding relationships and energy flow, and use them to identify trophic levels and navigate food webs
- Describe the trophic levels in a typical ecosystem. Discuss the flow of energy through the ecosystem, the relationship between the different trophic levels, and the factors that limit the number of trophic levelsWith the help of a diagram, represent the energy flow through different trophic level.Understand why food chains and webs can rarely have more than four trophic levels.
- discuss ecosystem productivity with examplesHow would you describe the trophic levels in a typical ecosystem? Discuss the flow of energy through the ecosystem, the relationship between the different trophic levels, and the factors that limit the number of trophic levels.Discuss how the flow of energy through ecological communities is depicted by trophic levels, food webs, and species diversity.
- In the trophic structure, autotrophs are living organisms that: Are at the top of the chain, referred to as tertiary producers. Photosynthetic organisms that produce their own energy Organisms that receive their energy by consuming producers such as plants Help to decompose the remains of dead organismsCreate a model which accurately, in detail, depicts the potential pathways of carbon (biomass) and energy in an ecosystem with at least five trophic levels (don’t forget your decomposers, they can count as one trophic level). Make sure to incorporate the multiple pathways that biomass and energy could take at each trophic level. Lastly, clearly illustrate how carbon and energy flow in this ecosystem. Be sure to include adequate levels of detail for all pathways and differentiate the flow of carbon and energy in your model.The mass of living material at a trophic level at a particular time is called as what?
