What happens when an organism from a higher trophic level eats an organism from a lower trophic level?
When an organism from a higher trophic level eats one from a lower trophic level, it gains energy and nutrients from the consumed organism. This contributes to the transfer of energy through the food chain and helps regulate population sizes in the ecosystem.
Which organism is at the higher trophic level - dolphins or plankton?
dolphins
What 3 factors account for decreasing biomass at higher trophic levels?
the flow of energy: primary production higher than trophic levels.
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.
Why does productivity diminish with increase trophic levels?
Due to poor trophic transfer efficiency, most energy is lost at higher trophic levels.
Give reasons for assigning trophic levels to each organism in an ecosystem.?
Photsynthesis is important to all trophic levels because it provides the energy needed by living things in all levels. Photosynthesis is how plants (in the autotrophic level) convert sunlight into the energy they need. Since animals in the higher trophic levels obtain energy by consuming other organisms, they are ultimatly dependant on photosynthesis too.
Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
Which term best describes energy transfer between trophic levels?
when energy is transferred to a higher trophic level some of the energy is trued into heat and is released
In food chains why do the arrows flow from the bottom upwards?
The energy is transferred from a lower trophic level to a higher trophic level when resources are consumed.
Why does only a small fraction of the energy at one trophic level become available to the next trophic level?
About 10% of the energy in the lower trophic level is passed to the next higher level. The 80% of energy that is left is used by that lower level for life processes or is lost as waste.
Explain why only 10 percent of the engery available at one trophic level is transferred to the next higher trophic level?
between each tier of the energy pyramid, energy is lost as heat
How much energy moves from one trophic level to the next?
Only 10% moves up...my daughter is writing a paper on this now!
