- Construct your model of the food chain/web by moving and linking (using arrows leading from those that eat and those that are eaten) all 8 images of the different species (trophic components).Energy Flow in Ecosystems Base your answers to the next 5 questions on the food chain below and on your knowledge of biology. grass → grasshopper frog snake > hawk 1. Draw an energy pyramid for this food chain. Hawk Snake Frog Grasshopper GrassHypothetical balanced food chain. Sun and Earth supply 6 units of energy to each plant. For higher tropic levels, individuals consume 2 units of energy each before passing the remainder to the next trophic level. The number of individuals in each trophic level is given below. Complete the table below by computing for the number of energy units in each column. Answer the following questions: Discuss how the food chain works. Where does each trophic component or level get its energy (food) from? What is the ultimate source of energy for all components of the food chain? Which component got the highest amount of available energy/individual? Why do members of this component need the most energy?
- Background A trophic level, or feeding level, is made up of all the organisms whose energy source is the same number of consumption steps from the sun in a given ecosystem. The trophic level of plants or producers is 1, while that of herbivores is 2 and that of animals that eat herbivores 3. Higher trophic levels can exist for animals even higher on the food chain. In this exercise, you will compute numerical values for human energy needs based on diets at different trophic levels. In this case study the owner of a farm raises soybeans and chickens. Grasshoppers feed on the farmers soybeans, and are in turn eaten by the chickens. Humans can, though rarely do, eat grasshoppers for sustenance. Humans can also eat soybeans. For the purpose of this exercise, make the following assumptions: A human requires 1 chicken/day There are 365 days/year 1 chicken eats 25 grasshoppers/day 1 grasshopper requires about 30 g of soybeans/year 1,000 grasshoppers have a mass of 1 kg 1 human requires…Background A trophic level, or feeding level, is made up of all the organisms whose energy source is the same number of consumption steps from the sun in a given ecosystem.

- Hypothetical balanced food chain. Sun and Earth supply 6 units of energy to each plant. For higher tropic levels, individuals consume 2 units of energy each before passing the remainder to the next trophic level. The number of individuals in each trophic level is given below. Complete the table below by computing for the number of energy units in each column and answer the questions below.- U3:L1:E1:Flow of Energy and Matter rmat Tools Add-ons Help Last edit was 34 minutes ago Food Webs How would the oceanic food web be affected if all of the krill were removed from the ecosystem? (multi-sentence answer required) How would the oceanic food web be affected if all of the plankton were removed from the ecosystem? (multi-sentence answer required)List two ways in which you could apply these concepts : (a) “as energy flows through ecosystems in food chains and webs, the amount of chemical energy available to organisms at each succeeding feeding level decreases” and (b) “matter, in the form of nutrients, cycles within and among ecosystems and the biosphere, and human activities are altering these chemical cycles.” to making your lifestyle more environmentally sustainable.
