It is transferred only when an organism consumes a producer.
It is transferred when one organism consumes another.
Energy flow through living organisms in an ecosystem occurs through several processes:
1. Energy is produced by all organisms through the process of photosynthesis or chemosynthesis. Autotrophs, such as plants and some bacteria, convert solar energy or chemical energy into organic compounds, which can be used as food and serve as a source of energy for other organisms.
2. Energy is transferred when one organism consumes another. Heterotrophs, such as animals, obtain energy by consuming other organisms, including both plants (producers) and other animals (consumers). This transfer of energy occurs through the food chain or food web, as energy is passed from one trophic level to another.
3. Energy is shared between organisms in the form of heat. As organisms carry out metabolic processes, a significant amount of energy is lost as heat. This heat energy is exchanged between organisms in the environment, contributing to the overall energy flow within the ecosystem.
4. Energy is also transferred when an organism consumes a producer. In ecosystems, primary consumers (herbivores) feed directly on producers (plants) and obtain energy by consuming plant tissues. This transfer of energy from producer to consumer is an essential process in energy flow within the food chain.
Overall, energy flows through living organisms in an ecosystem through the interconnected processes of energy production, consumption, heat exchange, and the transfer of energy between trophic levels.
