21 lis 2023 · A food chain shows the linear transfer of energy between different species in the form of a diagram. Food chains incorporate different trophic levels and can show exactly how energy...
Students use the phenomenon of owl pellets to construct a model food web for barn owls. Using the food web and simple calculations, they track the flow of energy and biomass through the food web, enforcing the concept of matter and energy conservation.
Using the information collected from the pellets, create a diagram of a food chain with an owl at the top level. Use an arrow to show which organism is the consumer or predator. Dispose of all owl pellet materials and disposable dissection tools and place in an outdoor trash receptacle.
Using the information in the overview or the owl pellet dissection results, construct a simple food web for a barn owl. Label the trophic levels and type of consumer.
Each food chain is a descriptive diagram including a series of arrows, each pointing from one species to another, representing the flow of food energy from one feeding group of organisms to...
Given a list of findings from owl pellets, students can research the prey animals found in the owl pellet and determine the diet of that prey from a field guide. From there, students can reconstruct the owl’s food chain or web to the garden (producer) level with the sun as the energy source.
