Energiakäiku
Energiakäiku refers to the energy flow or energy transfer within an ecosystem. It describes how energy moves from one trophic level to another, starting with producers (like plants) and moving up to consumers (herbivores, carnivores, omnivores) and decomposers. The primary source of energy for most ecosystems on Earth is the sun. Producers capture this solar energy through photosynthesis, converting it into chemical energy stored in organic compounds.
When an organism consumes another, the energy stored in the consumed organism is transferred to the consumer.
The concept of energiakäiku is crucial for understanding ecosystem dynamics, such as population sizes and the
