Question

The number of organisms in trophic level,which group of organisms are more in number and which are less in number

Answer 1

producers are more and apex consumers are less

Answer 2

The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.
