In a food web, organisms are organized into trophic levels based on their feeding relationships and energy flow. Producers, such as plants, form the base by converting sunlight into energy through photosynthesis. Primary consumers, like herbivores, rely on these producers for energy, while secondary and tertiary consumers depend on the consumers below them. This interconnected system illustrates how energy is transferred through various levels of the ecosystem, highlighting the importance of each organism in maintaining balance.
A consumer depends on the trophic level below it for energy.
A consumer depends on the trophic level below it for energy.
This is because energy is lost at each trophic level. The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
This is because energy is lost at each trophic level (from all the activity done by that level, e.g., running, climbing, fighting) . The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
Trophic level efficiency is typically measured by calculating the amount of energy transferred from one trophic level to the next. This is done by analyzing the ratio of energy present in the biomass of one trophic level compared to the trophic level below it. The efficiency of energy transfer between trophic levels is usually around 10%, meaning that only around 10% of energy is transferred from one trophic level to the next.
The biomass of a species decreases with increasing trophic level due to energy loss along the food chain. Each trophic level consumes energy and nutrients from the level below, resulting in a smaller overall biomass at higher trophic levels. This is known as the 10% rule, where only about 10% of energy is transferred from one trophic level to the next.
Each trophic level has about 10% less energy available than the level below it. This is due to energy being lost as heat during metabolic processes and as it moves up the food chain.

The energy pyramid is made up of trophic levels, which represent the different levels of organisms in an ecosystem based on their position in the food chain. It shows how energy flows through an ecosystem, with each trophic level receiving energy from the level below it and transferring some to the level above. The pyramid reflects the decreasing energy available at each successive trophic level due to energy loss through metabolism and heat.

Trophic level
Energy is lost as heat during metabolic processes, limiting the amount of energy transferred to the next trophic level. Additionally, not all organisms at a lower trophic level are consumed by organisms at the next trophic level, further reducing energy transfer efficiency. This results in only about 10% of the energy being transferred to the next trophic level.
