In a terrestrial ecosystem, mice eat the corn from the field, and the hawks eat the mice. which explains whether or not the hawks will get all the energy contained in the corn that the mice have eaten?
the hawks uses some of their energy to catch and digest the mice; therefore they will not get all the energy contained in the corn that the mice have eaten.
the mice use some of the energy in the corn to carry out their life processes; therefore the hawks will not get all the energy contained in the corn that the mice have eaten.
energy can neither be created nor destroyed; therefore the hawks will get all the energy contained in the corn that the mice have eaten.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
