Energy transfer through trophic levels
WebAssessment: Energy Flow in Ecosystems: Energy Pyramids - A formal assessment with a focus on inefficiency of energy transfer between trophic levels in an ecosystem. The Evaluation phase is the last step of the 5 E model. Here is a formal assessment to see what students have learned throughout the lesson sequence. WebTrophic levels can be represented by numbers, starting at level 1 with plants. Further trophic levels are numbered subsequently according to how far the organism is along the food chain. Level 1 Plants and algae make …

Web6. Calculate the percent of energy that is transferred from the first trophic level to the second trophic level. Divide energy from trophic level one and multiply by 100. This amount is the percent of energy transferred. Remember to add a percent sign. 7. Calculate the percent of energy transferred from trophic level 2 to trophic level 3. 8. WebThe fact is, after four to six energy transfers, there is not enough energy left to support another trophic level. In the Lake Ontario ecosystem food web, only three energy transfers occurred between the primary producer (green algae) and the tertiary, or apex, consumer (Chinook salmon).
