A team of scientists conducted a study of grassland ecosystem and estimated the total energy at each trophic level. Their data i
s shown below Explain the relationship between trophic levels and energy. Be sure to include The roles of the organisms found at the different trophic levels How each trophic level obtains energy? Why the available energy changes at each level?
In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.
The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.
