In Ecology, the transfer of energy from one trophic level to the next typically follows the 10% rule, which posits that only about 10% of the energy from one trophic level is passed on to the next level. This means that when organisms consume energy (in the form of food), a significant portion (approximately 90%) is lost primarily through metabolic processes, heat production, and non-digestible materials.
For example:
- If a primary producer (like a plant) captures 1,000 calories of energy from sunlight, the primary consumer (like a herbivore) that eats the plant will only extract about 100 calories of energy from it.
- Similarly, if that herbivore is then consumed by a secondary consumer (like a carnivore), it will only receive about 10 calories of energy from it.
This concept highlights the inefficiency of energy transfer through the food chain and is crucial for understanding ecosystem dynamics.
