What is transferred from organism to organism in a food chain?
energy is transferred from on animal to the other animal. Because energy can't be destroyed only transferred
How much energy Is transferred between Food chain?
Unfortunately for later members in the food chain, only 10% of the energy of the organism that they ate is absorbed an usable by the consumer.
Is about half the energy from one level transferred to the next?
No, only about 10-20% of an organism's energy is passed on to the next level of the food chain.
Does a food chain represent the only route for a transfer of energy?
Food chains are the transfer of energy from one living thing to the next up in the food chain but energy can be transferred in a living thing through: Movement Respiration Sensitivity(senses: sight, smell, etc.) Growth Reproduction Excretion Nutrition
What travels through the food chain?
Energy. In general, only about 10% of the energy available is able to be passed up the food chain.
What happens to the energy going up the food web?
First level is the plants, they capture energy from the sun and trap it in their molecules, sugar, etc. Second trophic level probably has to eat lots of plants just to put a little meat on their bones, so energy is being transferred, and eventually moves "up" only because the food chain is often looked at as a pyramid. Biomass pyramids are another way to describe this (or almost same) phenomenon.
Why must a producer be at base of every food chain?
Something can't come from nothing. Energy cannot be created or destroyed. It can only be converted and transferred. Producers are the only living organisms of earth that are able to convert sunlight to energy. If it was not at the bottom of the energy pyramid, the organisms below it would not exist because they were not getting energy from the producers.
When considering the transfer of energy how does being at the top of the food chain affect an organism?
The top of the food chain has very little energy in the form of food to take in. There may be only a very few top predators in some energy poor systems.
Explain why a food chain can have no more than three or four links?
As more organisms participate in a food chain, less energy is transferred from the prey to the predator. On average about 10% of the energy on one level is transferred to the next level. The other 90% is either lost as heat or cannot be digested. Example: A plant contains 10,000 kilocalories. The plant is eaten by an insect that will only gain 1,000 kilocalories of energy. Next, the insect is eaten by a fish which gains 100 kilocalories of energy. A bird consumes the fish and gains 10 kilocalories of energy. Finally, a mountain lion catches the bird and gains only 1 kilocalorie of energy.
Does the bottom of the food chain have the least or most energy?
By bottom, do you mean where the food chain starts(with plants) then YES :) only 10% passes on to each level :)
Only about 10 percent of the energy in an organism is passed on to the next level of a food chain. Look at this food chain grass and rarr rabbit and rarr hawk What percentage of the energy stored b?
Well think about it. If only 10 percent energy goes around. Do the math
How does the nutrients and energy pass from animal to animal in the food chain?
eat another energy pass only 10 percent
