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.
CONTEXT
The earth is comprised of many different life forms, including plants, animals, humans, and
other organisms. These various life forms are highly interdependent and have formed important
systems that continually reshape the planet's landscapes, oceans, and atmospheres.
Booming human population growth over the last two centuries has put, and continues to put,
many of these life-sustaining systems out of balance and in serious jeopardy, endangering many of
the plant and animal species that human beings directly and indirectly depend upon for long-term
survival.
Bigger human populations naturally mean increases in human activities worldwide, leading to
changes in landscapes, oceans, atmospheres, and the path of human history. For example, as noted
in the benchmark of this lesson, human activities like reducing the amount of forest cover, increasing
the amount and variety of chemicals released into the atmosphere, and intensive farming, have
changed the earth's land, oceans, and…
Create a model which accurately, in detail, depicts the potential pathways of carbon and energy in an ecosystem with the following organisms: grass, mice, snakes, and hawks (don’t forget your decomposers as well).Make sure to incorporate multiple pathways and clearly illustrate how carbon and energy flow in this ecosystem.

The company owns thousands of acres of land surrounding one of its powerplants and leases much of this land to local farmers for agriculture. However, local environmental groups have been stating concerns in the local newspaper about the loss of insect biodiversity on in meadows surrounding the agricultural activities. You have been tasked by the company to develop an experiment to investigate whether a loss of insect biodiversity is occurring in these meadows because of these agricultural activities. Action Steps: Propose a coherent and testable hypothesis that captures some aspect of this concern. Identify the independent and dependent variables in this experiment.

Suggest possible solutions that would reduce the impacts of nutrient and pesticide runoff, while incorporating the three considerations of human sustainability. In other words, come up with a solution that would reduce ecological impacts of pesticide and nutrient runoff, while allowing farmers to ultimately meet their income needs in a socially equitable way (does not exploit anyone in the process). • Show lessarrow_forwardExplain how energy flows in an ecosystem.
