What is flow of energy in ecosystem?
Energy flows from one trophic level to the next (Producer->Primary Consumer->Secondary Consumer). Energy transfer becomes less efficient as it's being transferred; seeing as it is partly used by the organism for metabolic processes.
In the photosynthesis process what trophic level occur?
Photosynthetic organisms make up the producer trophic level.
Why do food chains not exceed 4 links?
because the way a food chain works is energy is transferred between trophic levels, but as you move up each trophic level, about half of the energy is lost, which means when you get to the fourth trophic level, only about 10% of the original energy is remaining, so adding another level would mean that the creature would have to consume 10 times as much of its respective prey to get the energy equivalent of 1 of the creatures at the first trophic level. so in other works, energy consumption would be too inefficient
Why are there so few organisms at the top of an energy pyramid?
This is because only about 10% of energy is transferred from one trophic level to the next. The other 90% or so is used up by the organism itself for life processes, digestion, excretion, growth, movement and transpiration for plants. Therefore the amount of energy decrease up the trophic levels and the higher the trophic level, the less the energy received.
What are three reasons why energy transfer between trophic levels is not 100 percent?
Energy transfer is inefficient because energy is lost while moving from one trophic level to another. This is because * Not the entire organism is consumed or digested. Parts such as rootr, woody stems, bones, scales, feathers etc aren't eaten, and some materials that are such as cellulose cannot be digested. * Energy is used up by organisms in each trophic level for movement and transport inside their bodies. * Energy is used in respiration and is released from the body of the organism as heat. * Energy becomes lost in excretion.
What trophic level is the energy that is not passed on to the next trophic level?
It's used up by the metabolism or excreted as waste.
How much energy moves from one trophic level to the next?
Only 10% moves up...my daughter is writing a paper on this now!
Are biomass and trophic level related?
Each trophic level contains one-tenth as much biomass as the level below it and ten times as much biomass as the level above it.
What energy is available each step up the pyramid?
Ten percent of the energy in each trophic level makes it to the next level.
What happens to the amount of energy available to each successive trophic level in a food chain?
It decreases because there are less and less animals as you go up.
Why is so little of the energy from one trophic level transferred up to the next trophic level?
All of the energy that enters an organism is not available to the next trophic level. This is because while the organism has the energy they use most of the energy up before the next level eats that level.
What is the lowest level of the food chain?
The organism that has the least energy in the food chain is... well it depends because the ferther you go up in the tropic level the less energy you have. every time you go up you lose 10% of the energy.
What happens to energy that is not passed on to the next trophic level?
It's used up by the metabolism or excreted as waste.

Phytoplankton in the ocean are in which trophic level?
Phytoplankton make up the whole first trophic level.
Organisms at the first trophic level are called?
Producers make up the first trophic level. A trophic level is each step in a food chain or food web is called a trophic level.
In the photosynthesis process what trophic level occur?
Photosynthetic organisms make up the producer trophic level.
