What happens to the number of organisms as you move up the tropic levels of an energy pyrimaid?
As you move up the trophic levels of an energy pyramid, the number of organisms generally decreases. This decline occurs because energy is lost at each trophic level due to metabolic processes, heat, and inefficiencies in energy transfer, typically following the 10% rule. Consequently, there are fewer organisms at higher levels, such as carnivores, compared to lower levels like primary producers. This results in a pyramid shape, with a broad base of producers and a narrow top of top predators.

What happens to energy in an ecosystem?
Energy flows through an ecosystem, starting with producers who convert sunlight into chemical energy through photosynthesis. This energy is then transferred through the food chain as organisms consume each other. Eventually, energy is lost as heat during metabolism and at each trophic level, limiting the amount available for higher trophic levels.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
Why must there be more organisms at the bottom of the pyramid of numbers at the top?
There needs to be more organisms at the bottom of the pyramid of numbers because each trophic level requires energy from the level below it, resulting in a decrease in available energy as you move up the food chain. This means that more organisms are needed at lower levels to support the energy requirements of those at higher levels.
What is the link between different trophic levels?
Trophic levels are different positions in a food chain, representing the energy transferred between levels. Producers are at the base, followed by primary consumers, secondary consumers, and so on. Energy is transferred between trophic levels as organisms are consumed, with only about 10% of energy passing to the next level.
Why are matter and engery transferred through an ecosytem?
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
What happens to the energy that is not passed through the trophic levels of an energy pyramid?
It used by the organisms at each trophic level to keep themselves alive.
What happens to the number of organisms in each classification levels as you move from the kingdom level to each of the next levels?

How does the energy flow chart in an ecosystem illustrate the transfer of energy between different organisms and trophic levels?
The energy flow chart in an ecosystem shows how energy is transferred between different organisms and trophic levels. It demonstrates that energy is passed from one organism to another as they consume each other. This process creates a flow of energy through the ecosystem, with energy decreasing as it moves up the trophic levels. The chart helps illustrate the interconnectedness of organisms and how energy is essential for sustaining life within the ecosystem.
Why do different tropic levels have different amounts of energy?
Different trophic levels have different amounts of energy because energy is lost as it moves up the food chain. Organisms at higher trophic levels must consume a larger amount of lower trophic level organisms to obtain enough energy to sustain themselves. This inefficiency in energy transfer limits the amount of energy available at each trophic level.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
How is energy transferred among organisms?
Energy is transferred among organisms through food chains or food webs. Producers, such as plants, convert sunlight into energy through photosynthesis. This energy is then passed on to consumers through consumption of other organisms. Energy is lost as heat at each trophic level, resulting in less energy available for organisms at higher trophic levels.
What happens to the number of organisms as you go along any food chain in the food web?
The number of organisms typically decreases as you move up the food chain. This is due to energy loss at each trophic level, with only about 10% of energy being transferred from one level to the next. Therefore, less energy is available to support a large number of organisms at higher trophic levels.
Why must there be more organisms at the bottom of the pyramid of numbers at the top?
There needs to be more organisms at the bottom of the pyramid of numbers because each trophic level requires energy from the level below it, resulting in a decrease in available energy as you move up the food chain. This means that more organisms are needed at lower levels to support the energy requirements of those at higher levels.
What happens to the amount of energy in the pyramid as it moves up the levels of the pyramid?
it increases
How do organisms transfer energy?
Food energy flows from one organism to the next and to the next and so on, with some energy being lost at each level. Organisms in a food chain are grouped into tropic levels, based on how many links they are removed from the primary producers. In tropic levels there may be one species or a group of species with the same predators and prey.
What happens to biomas as you move up the biomas pyramid?
As you move up the biomass pyramid, the amount of biomass decreases because energy is lost as you move up trophic levels through energy transfer from one organism to another. This is due to the inefficiency of energy transfer as organisms consume one another.
