Using the concepts of trophic levels and energy flow, explain why the ecological footprint of a vegetarian person is smaller than that of a meat-eater

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…

In the trophic structure, autotrophs are living organisms that:     Are at the top of the chain, referred to as tertiary producers.     Photosynthetic organisms that produce their own energy     Organisms that receive their energy by consuming producers such as plants     Help to decompose the remains of dead organisms

The term food web refers to the:    Question 10 options:   Rate at which the primary producers can incorporate energy from the sun.   Total weight of the living or previously living organisms in an area at one time.   An organism that can make its own food using energy from inorganic molecules instead of the sun.   A non-linear representation of all the trophic levels in an ecosystem.

Give an account of energy flow in an ecosystem.

Name the trophic levels in an ecosystem and explain how energy moves through the trophic levels. Can you use the words food chain and food web in the discussion.

Explain how/why ecologists can use trophic cascades to understand the “bottom up” vs. “top down” dynamic of a system

If 20J of energy is trapped at producer level the how much energy will be available to the last animal as food in food chain?

Give an example of an animal in this food web at each of these trophic levels Snake Fox Hawk Producer: Bird Frog Primary Rabbit Grasshopper consumer: Mouse Grasses secondary consumer: Tertiary Consumer:

Considering the energy that is lost as heat to the environment when one organism consumes another, mention the correct order of the trophic levels ranked from greatest energy to least?
