7th grade responses to quote

Three hundred trout are needed to support one man for a year. The trout, in turn, must consume 90,000 frogs, that must consume 27 million grasshoppers that live off of 1,000 tons of grass.
-- G. Tyler Miller, Jr., American Chemist (1971)


  • For me this means the man takes more than just the 300 trout's life. When the man eats the trout, he just ate frogs and grasshoppers because the trout ate them. For example Man --> Trout --> Frogs --> Grasshoppers --> grass. So all of the 90,00 Frigs, 1,000 tons of grass, and 300 trouts are dead just because the man has to survive that year. So the man is not just eating the trout, its eating more than that trout.
  • I think a man should protect the organisms and be thankful to the environment because 270000 grasshoppers are being sacrificed just for you. Imagine that your a grasshopper and you have to be giving away your life to the frogs, are you happy about that? So if this system is real, you should be doing something that may help them.  Or else, stop eating trouts and die, cause you just act like a deadly scavenger!
  • I think it's a food chain, the human ate the trout that ate the frog before being killed by the human, the the frog ate the grasshoppers before being eaten by the frog and the grasshoppers ate grass before being eaten by the grasshoppers. Which means that the human did not only ate three hundred little trout, he ate, 90,000 frogs, 27 million grasshoppers, and 1,000 tons of grass.
  • I think if there were no 1,000 tons of grass in that ecosystem, the 27 million grasshoppers might not survive, which mean that there won't be 90,000 frogs, if the trout only eat frogs, and if the there were no frogs in that ecosystem those trout might be dead, maybe there will be fewer human because there are not enough food for them. 
  • I think grass is important for everything because its on the bottom of the food pyramid. If there are no grass in our ecosystem, there won't be grasshoppers because grasshoppers will only eat grass, and if there are no grasshoppers, there won't be frogs, and if there are no such thing as frog in our ecosystem, that means there won't be trouts. And since there are no trouts, man can't be supported and eventually there will be no man in the ecosystem.
  • The quote makes me think all the living things must need food to survive, if there is no food to eat, this ecosystem might be ruined. But, those living things might get less in the future if the ecosystem is still running.
  • I think it means one man needs to eat three hundred trouts one year, and that equals 90,000 frogs, and 27 million grasshoppers , and 1,000 tons of grass. Not saying that the man eats all of this, but that 1,000 tons of grass is enough to feed 27 million grasshoppers, and 27 million grasshoppers is enough for 90,000 frogs. So this is a food chain. 
  •  My first thought on this article was "Wow! I never knew trout ate frogs!" But then I thought deeper. If each person ate 300 trout, and each trout ate 300 frogs, of which each one ate 3000 grasshoppers, together the grasshoppers eat 1000 tons of grass...
And if there are 7 billion people on earth...

then each year, there will be a total of 2100000000000 trout eaten.
It will take 630000000000000 frogs to sustain the trout.
A total of 1890000000000000000 grasshoppers eaten by the frogs.
1890000000000000000000 tons of grass will be required to feed those grasshoppers.
Still sustainable, but it is straining.

Now, if human populations continue to grow globally, then in a decade, humans will no longer be sustainable. Earth will no longer be able to harbor us. So we must look for a new way of life. Either we find a way to keep our growth sustainable by mass agriculture and aquaculture, or we scan the stars for a virgin planet that will take our weight, or at least half of it.


  • This article is basically talking about the cycle. To support one man for a year, the man has to eat as much as three hundred trouts. After been eaten by human, the trouts have to eat as much as 90,000 per year. Also the frogs have to eat has much as 27 million grasshopper. This cycle is to support one man per year, the man has to eat the trouts to get nutrient and live. Also the trouts, frogs, and grasshopper.
  • Energy decreases as it moves from grass to man. For me this means organisms that gets consumed needs to reproduce more than the consumers because they lose more of theirs than the consumers. If the organism doesn't reproduce more, the organism will gone extinct. The man actually needs the trout, frog, grasshopper, and the grass, because if there is no grass, grasshoppers will lose their food and maybe gone extinct because they need it. Without grasshoppers, the frog might die out because frog needs the grasshoppers. And this is goes on and on just to feed one man. For all these reasons I think this quote means that organism that gets consumed will need to reproduce more than the consumers.
  • I think we eat far too many trout a year, cause if we eat 300 trout, then there's 90,000 extra frogs, and then there's 27 million extra grasshoppers, and there's more grass left for us to destroy...So we need to eat less trout, and let those nasty frogs and grasshoppers not invade everywhere from overpopulation. Frogs are nasty looking if they jump on you, so if we eat too many trout, then there's less frog control, which means there's grasshoppers getting eaten and there's more frogs to trample us over, and that will cause a apocalypse...Grasshoppers will be dead forever....
  • The quote is telling us as you move to the bottom of the food chain the amount become larger. In each stage of the food chain it relies on other for food. The quote shows human is on the top of the food chain. The main resource for the food chain to occur is the grass. If we don't have the main resource everything will die out and food chain won't occur. 
  • This quote is about a food chain, it want to tell us that the food has at least three hundred times larger than the living things, so that the man can be supported. The grass are very important to the grasshoppers, because if the place didn't have any grass their will not be ant grasshoppers their. If their is not any grasshoppers their will not be any frogs... So any small things that animals ate is very important to the ecosystem!
