How do energy and mass flow through a food web? Activity Objectives 1. Use owl pellets to model a food web. 2. Calculate energy transfer and biomass at each trophic level of a barn owl food web. Next Generation Science Standards* (NGSS) MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living
Use the food web to identify the pattern in food mass consumed for the primary and secondary consumer trophic level. 2. The sun provides 100% of the energy needed by plants.
Use owl pellets to model a food web. Calculate energy transfer and biomass at each trophic level of a barn owl food web.
Using Table 3, construct a diagram of a food web (of at least five animals), with an owl at the top trophic level. Use arrows to show which organisms are consumers and which are predators. Ensure you label the trophic levels and class of consumer. Include the Sun as the energy source for plants.
Owls are nocturnal raptors that feed on small mammals, birds and reptiles. Owls swallow their food whole or if too big, may tear it into chunks. Owls are not able to digest hair, bones or feathers. The owl digestive system has a specialized section that presses the undigested portions together forming a pellet.
