Scientists used to say that all living things depend on the sun. Explain why this statement is no longer valid
Alex M

because now we know things that live deep in the ocean that use chemosynthesis to live down there.
Shamica G
10/31/2010 10:34:11 pm
It valid because new things was created
Phillis Troupe
10/31/2010 10:34:58 pm
Scientists cant say all living things deoend on the sun because some of them eat other living things.
Ja'Ron D
10/31/2010 10:35:19 pm
because plants deep in the ocean use chemicals for energy
Nina B
10/31/2010 10:35:32 pm
this statement is no longer true because they discover that all living thing does not depend on the sun, like bacteria.
Dejon S.
10/31/2010 10:35:49 pm
The animals that live in the ocean live off of water
Alicia B
10/31/2010 10:36:05 pm
the statement is no longer valid because different plants and rely on different things and in the ocean use chemosynthesis.
Dion
10/31/2010 10:36:17 pm
This statement is no longer valid because not all organisms use photosynthesis some organisms use chemosynthesis to survive.
George G.
10/31/2010 10:36:26 pm
Because some organism use chemosynthesis to make their food and to provide energy
T-mart
10/31/2010 10:36:29 pm
because the way we live now determains that we dont need the sun for everything
justin arnold
10/31/2010 10:36:35 pm
because there are some organisms that dont need the sun to live
tashounda

scientist use to say all living things depend on the sun because they thought that there were only living things that depended on the sun. but there are not as meany organism that depend on the sun for energy
veli dullovi

not all organisms use photosynthesis some organisms use chemosynthesis to survive.
Chester D.
10/31/2010 10:37:06 pm
It valid because all living things are created.
LaRon T
10/31/2010 10:37:33 pm
because their are some things that dont need the sun to survive
Asha M
10/31/2010 10:37:48 pm
With the research we have today we learned that it takes more than the sun for living things to depend on.
Steven B
10/31/2010 10:41:04 pm
This is no longer valid because some spieces dont eat energy from the sun.
E.H

protons,electrons,nutrons are the ones that makes up atom.
Ja'Ron D.
11/2/2010 10:11:20 pm
because plants deep in the ocean use chemicals for energy
Chester D.

the plants are effected (die) first, then then the animals that eats plants (herbivores), then the higher species eventually die.

A drought would effect an grassland food web because the energy level would decresse. It would first effect the producers and then the primary consumers.
LaRon T
11/2/2010 10:12:57 pm
their is no water for the plants to survive and the hervibores will be affected and the animals wil. get affected to
Alex M
11/2/2010 10:13:01 pm
the primary producers would be affected because they need the water to help the photosynthesis process to make their food so that they can live.
Dion
11/2/2010 10:13:49 pm
a drought could affect a grassland food web because it will have no water ro survive or sustain itself. the drought will affect the producer trophic level. it will affect them first because they are the basis of a trophic level pyramid.
Alicia B
11/2/2010 10:14:34 pm
the plants would be effected first because of the rain would flood the plants and then the primary consumers will suffer because they will have no food to eat off of.

A drought could affect a grassland food web because it will have no water to survive. The plants would get affected first.
Steven Baynham
11/2/2010 10:15:24 pm
The primary producers will be affected because there is no water and they cant feed.
T-mart
11/2/2010 10:15:29 pm
it would make the land nasty and dry.
tashounda
11/2/2010 10:15:31 pm
a drought might effect a grassland economy by destroying the grass and it kills all the other animals because the resources would not have any energy to produce anything.which trophic level the drought kills first is the producers (plants),then it will kill the primary consumers, then the secondary consumers ,then the tertiary consumers.
Josh Bruh
11/2/2010 10:21:45 pm
it would effect it because the grass would die so smaller animals wouldnt be able to eat then nobody eat
Shamica G
11/2/2010 10:58:39 pm
no rain can keep the grass from growing.producer because first level and have to go through them first
justin arnold
11/2/2010 11:33:10 pm
a drought would cause the grass to stop growing and die and the forst food group it would effect the lowest part of the food chain first

an energy pyramid shows the flow of energy in a food web because between each tier, up to 90% of the energy is lost as heat into the atmosphere.
Alex M
11/7/2010 09:15:44 pm
by showing the different trophic levels
Alicia B
11/7/2010 09:16:34 pm
Some energy is stored within an organism and some energy is dissipated into the environment.
Nina B
11/7/2010 09:16:42 pm
An Energy Pyramid compares the energy used by producers, primary consumers, and other tropic levels.
George G.
11/7/2010 09:17:27 pm
It shows that 90% of an animals energy go in to the environment and 10% of it go to the next animal that ate it .
T-mart
11/7/2010 09:17:28 pm
It will show you the different trophic levels and show you how much nengery is needed
veli dullovi
11/7/2010 09:17:33 pm
each tier on the food web loses 90% of the energy into the atmosphere.
Shamica G
11/7/2010 09:17:36 pm
it shows how available energy is among trophic levels in an ecosystem
LaRon T

An Energy Pyramid compares the energy used by producers, primary consumers, and other tropic levels.
Steven B
11/7/2010 09:18:51 pm
The energy web emphasizes complicated feeding relationship and energy flow in an ecosystem.
Phillis Troupe
11/7/2010 09:19:16 pm
The food pryamid decribes the food web from least to greatest, in supplying the most energy.
Josh Bruh
11/7/2010 09:19:44 pm
Because it shows how much energy there is goin least to greatest
Dejon S.
11/7/2010 09:20:53 pm
because it shows how much energy there
Ja'Ron D.
11/7/2010 09:21:06 pm
because plants deep in the ocean use chemicals for energy
tashounda
11/7/2010 09:23:20 pm
an energy pyramid describes the flow of energy in a food web because the energy pyramid displays the flow of energy through an array of points and and arrows
justin arnold
11/7/2010 09:26:45 pm
the energy pyramid shows how much energy each group of organisms has.
lonnell b
