Create 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.

Optional Exercise
Barn Owls produce 2 pellets per day. Assume each pellet contains 80g of biomass. Also assume that one 40g vole can cause
50 cents of crop damage to a farm per season. If a Barn Owl family of seven (2 adults and 5 young) lives on a farm for 12 weeks
and feeds entirely on voles, how much will the farmer save in crop damages?

- Find the flaws! Energy in a terrestrial ecosystem moves from the sun, to producer, to primary consumer, to secondary consumer, ending in a tertiary consumer. Producers are heterotrophs and consumers are autotrophs. Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick. The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. Carbon can cycle either quickly or slowly. “Fast” carbon cycling happens in biology.…arrow_forwardQ4.22.

When nutrients are retained by a system, they Reset Use the following information for the last question. Farmers often rely on riparian forests- strips of forest vegetation immediately adjacent to streams-to reduce the export of nutrients via streams. The nitrogen budget to the right represents a system containing both corn fields and riparian forest.
