Someone smart please answer this

The population density of large carnivores is always less than their prey. Using the idea of an energy pyramid and the 10% rule of energy transfer, why does this occur?

Ho ho ho....GREEN GIANT ;-)

 

[rsnoble]

Because the caloric/energy value of all prey can only sustain 10% of the carnivores.

Or an amount = to 10% I mean.

ok, ill take a stab at it and see what i can come up with. if u think of it in terms of life, the struggle among a variety of organisms is towards a vanishing amount of energy. "Life itself seems to only operate on ten percent of the suns energy reaching the earths surface, the portion fixed by photosynthesis of green plants. Te free energy is then discounted as it passes through the food webs from one organism to the next: very roughly ten percent passes to the herbivores that eat plant and bacteria, ten percent of that or one percent of the residue to the other middle level carnivores that eat the low level carnivores, and so on upward to the top carnivores, which are consumed by no one except parasites and scavengers. Top carnivores live on such a small portion of life's available energy as to always skirt on the edge of extinction.
THe energy pyramid is a straightforward consequence of the law of diminishing energy flow. The second pyramid is composed of biomass, the weight of organisms. By far the largest bulk of the living world is contained in plants. the second largest amount belongs to the scavengers and other decoposers. Each level above the plants diminishes thereafter in biomass until you come to the top carnivores."


Hope that helps.

In other words, the big ones have to eat a lot more and it is easier for rabbit to eat grass than it is for a coyote to catch a rabbit.

Efficiency of Transfer?

HMMM, I thought it was the less food deal, just thought it was too simple. thanks kikers

PatsFan
I was thinking in my head, anyone who jacks this thead I should tag em with red shit. but that was funny

who the hell is kikers?

 

[Tooshort]

I was just thinking the same thing. Big bad id hit u back but i dont know how.

 

[rsnoble]

Shananigans!!! This is pure set up bullshit between bigbadbuff and too fucking short. Now who in the fuck would just come on here and pull that kinda shit out of their fucking ass.

You must both be neo-cons.

Fucking idiots, trying to come on EF and show the poundage of their pea brains.

 

[Tooshort]

whoa there chuckles...calm down.

It's called a enviromental science class you cock suck. what's a neo-con?

Anybody he can. Until he gets caught or has enough money from scamming, I guess, but what`s a neo anyway?

A whole lot less than 10% of the suns energy reaches the earth. More like .000000000000000000009% (+probably more zeros)

If the earth was as big as its orbit, say like a ring around the sun then it still would not take up 10% of the suns energy. We are that small.

 

[Tooshort]

"Life itself seems to only operate on ten percent of the suns energy reaching the earths surface, the portion fixed by photosynthesis of green plants"

That doesnt mean that only 10 percent reaches the earth from the sun. It merely means that life operates on only ten percent.

 

[Mactep]

Life is on earth. If 10% of the suns energy doesn't reach the earth, then how can life operate on 10%.

The law of thermodynamics states that in an exchange of energy some is lost. If .0005% of the suns daily energy reached us, life could only utilize a maximum of less than .0005%, certainly not more. That would be if every single bit of the suns energy is convereted into usable energy for life forms. Much of the suns light is reflected (albedo) and is lost into space. Some is absorbed as heat by non-organtic materials, some damages life irreversibly, etc etc. I would say that 10% of the energy that reaches earth is used. Not 10% of the suns energy.

Ahh, too early in the morning, I see what you are saying now, basically the same thing I am saying. carry on.

I don't care if you have 5,000 cousines who are jewish one more time and your gone.
