There is less energy available to consumers(animals) ,because most of the energy from the sun is used by the producers(plants)
1- Producers- make their own food (plants, photosynthetic bacteria, etc.) 2- Primary Consumers- eat the producers, small (rodents, bugs, etc.) 3- Secondary Consumers- eat the primary consumers (ex: snakes) 4- Tertiary Consumers- eat the secondary consumers, larger, (ex: owls, humans) There are not many trophic levels because only 10% of the energy available at one trophic level is passed on to the next level, and so the amount of energy available after many levels is not able to support many organisms.
They are smaller in magnitude than those between lower energy levels.
all consumers
There are four trophic levels in an ecological pyramid. They are primary producers, primary consumers, secondary consumers, and tertiary consumers.

ECOLOGICAL food chains are typically short, consisting of not more than four or five trophic levels. This is usually explained by a reduction in the energy which is available to successive links in the food chain1,2. In contrast, we believe that the number of trophic levels is constrained by population dynamics and not by ecological energetics.
Because only a fraction of the energy used by a level is converted to biomass, less energy is available at higher levels.
