What is a trophic level and what determines an organism's trophic level?
A trophic level is the position an organism occupies in a food chain. It is determined by the organism's source of energy and nutrients. Primary producers occupy the first trophic level, herbivores occupy the second trophic level, and so on up the food chain.
The percentage of energy in one trophic level that transfers to the next level in the average ecosystem is?
The percentage of energy that transfers from one trophic level to the next is around 10%. This is known as the 10% rule, where only a small portion of energy is passed on due to energy loss through metabolic processes, heat production, and inefficiencies in consumption and digestion.
What is the average level for a key stage 3 sats paper?

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.
What is the relationship between the trophic level of an organism and the concentration of DDT in its body?
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
