- 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.

- A class is studying the tropic levels of an ecosystem. The pyramid of biomass shown is a model of these trophic levels. Which of the following is the best explanation of the available energy at each of the trophic levels in this ecosystem ? ANSWER CHOICES ARE IN THE PHOTO. thanks.PLEASE ANSWER A AND B As we know, energy is lost moving from one trophic level to the next (total energy moved from one trophic level to the next is usually estimated at 10%). The total loss is known as trophic efficiency. Trophic efficiency is made of 3 parts (3 places where energy is lost). You need to pick TWO of the three individual efficiencies that make up the overall trophic efficiency and for EACH, tell me: a. What do we call this part of trophic efficiency? b. How is energy lost in this part of trophic efficiency? c. We discussed characteristics of an organism or environment that made it more or less efficient in certain parts of trophic efficiency (we did not use this one in class, but for instance, endoparasites have a higher xxxxxxx efficiency than ectoparasites). Tell me what characteristics of an organism/ecosystem (other than the example above) would make it more or less efficient for this part of Trophic efficiency. (Make sure to say what characteristics makes it…Apply the second law of thermodynamics to the diagram below. Answer using 3 to 4 complete sentences.

- Organisms at a higher trophic level have less energy available.comment.When hunting disrupts the balance in the food chain by removing all owls, there will be no predators on snakes, leading to their increase in numbers. Considering the scenario where the number of lost owls (4) is replaced by snakes, compute for energy units following in completing the table below. Trophic Levels No. Individuals in Each Trophic Level No. of Units Received from Trophic Level Above No. Units Used / Individual (Resp) No. Units Used in Trophic Level No. Units Remaining & Passed on to Next Trophic Level Mean No. Units Available per Individual in Trophic Level SUN +E = 6 1) Plants 30 2 2) Grasshopper 19 2 3) Frog 12 2 4) Snake 8 + 4 = 12 2 5) Owl 0 2Energy flow or calorific flow in an ecosystem is described as an open system. Critically explain what this means with real life example.
