1. What does the suffix “troph” mean?
The suffix "troph" mean organism with nutritional requirements.
2. What do you think a trophic level is?
I think the trophic level of an organism is the position it occupies in a food chain.
3. How about food chains, food webs? Compare and contrast those terms you learned in biology.
For the food chains is that it show a single path of animals that eat each other. On the other side food webs is show how is plants and animals are connected to each other by different paths.
4. Quickly sketch a food chain using organisms that might be found on our school grounds.
a. What do you have to do to turn it into a food web? Do so.
I have to make connection to other to turn it into a food web.
5. Look at the following diagrams called Energy Pyramids.
a. What do they all have in common?
They all have in common is that they all display the transfer of energy form the bottom to the top.
b. How are they different from one another?
They different from one another is each of the pyramid has different type of animals of each levels.
6. Why are there are more organisms at the base and less organisms as you travel up the pyramid?
There are more organisms at the base and less organisms as you travel up the pyramid because the producers have more energy. It needs to be a more amount to support the other trophic levels.
a. Any idea what an energy pyramid shows?
An energy pyramid is that the transfer of energy from levels start from the bottom and going up. Each levels you suppose to loss 90% of energy.
7. Two of the pyramids have numbers. Do you see a pattern in the numbers?
A pattern in the numbers are going down (10%).
a. What might the numbers mean?
Might the numbers mean the amount of energy in joules.
1. Calculate the number of gh a hen needs to eat per year.
9125 grasshoppers a hen needs to eat per year.
2. How many gh are needed for a year’s supply of hens for you, the farmer?
3330625 grasshoppers are needed for a year's supply of hens for you.
3. What is the total mass in kg, of the gh needed to feed all the hens for one year?
3330.625 kg of the gh needed to feed all the hens for one year.
4. How many kg of soybeans are needed to feed all the gh for one year?
99918.75 kg of soyheans are needed to feed all the gh for one year.
5. Sources tell us that Native American Indians ate gh. So you can too! These early Americans could
collect about 90 kg of gh per hour, when they were abundant. How many people could the gh feed, compared to the one person that the hen fed? (Perhaps you could dip the gh in chocolate.)
90kg=90000gh. 90,000/600=150 people.
6. You need to consume 3000 calories/day. If you ate only soybeans how many grams of soybeans would you have to eat per day for calories alone?
909 soybeans you would have to eat per day for calories alone.
7. Cows produce about 19 kg protein/acre/year and soy produces 200 kg of protein/acre/year.
a. Which is more efficient to eat? Why?
The soy beans are more efficient to eat, because it produces more protein .
b. Have you ever eaten a soy burger (veggie burger)? Why or why not?
No, I have never eaten a soy burger, because I didn't know how much protein of soy has and for a regular burger.
8. In theory, the earth could support many more people if we ate at a lower trophic level.
a. List 2 benefits of doing this.
Healthier food at lower trophic levels, less hunger in the world.
b. List 2 drawbacks of eating lower on the food chain.
the 2 drawbacks of eating lower on the food chain are the less of the organisms in the lower trophic levels and more of the organisms of the higher trophic levels.
c. What are some benefits of being a vegetarian?
Some benefits of being a vegetarian is more energy at the bottom of the trophic level, so you're gaining more energy.
d. What are some drawbacks?
Limits to what you can eat, so you lack certain nutrients that only meat has.
9. And then there are fish to eat! Large predatory fish usually are found at the 3rd or 4th trophic level of an energy pyramid. What does this mean in terms of energy loss?
You lose 72.9% of the energy from the lowest level of a trophic pyramid. (90%*90%*90%)
10. Large predatory animals can also be problematic to eat because of bioaccumulation and biomagnification of toxins such as lead or mercury in their habitats. What do those two big words mean and why should this be considered when discussing food chains and trophic levels?
Bioaccumulation is the accumulation of a substance in a living organism. Biomagnification is the increase of a substance that occurs in food chain.It a considered because the food that we eat could have accumulated a dangerous toxin. This toxin could increase in the food chain, and when us humans eat it, we will also have the toxin in our body.
11. Do you think about the food you eat? Why or why not?
I don't think about the food that I eat because I always worried about when I don't have anything in my tummy.
The suffix "troph" mean organism with nutritional requirements.
