- Inefficient is the term that helps in describing the energy transfer between trophic levels.
- Primary producers are present in the first step of the food chain.
Further Explanation:
• Inefficient is the term that helps in describing the energy transfer between trophic levels.
The amount of energy decreases with each trophic level while going through the ecosystem. About ten percent of the energy is transferred to each level, and the remaining ninety percent is lost majorly during metabolic activity as heat. For example, if grassland consists of 10000 kilocalories, only 1000 kilocalories are transferred to primary consumers. By the time it reached the tertiary consumer, the maximum amount of energy is lost. The number of consumers in a particular trophic field depends on its size and energy richness.
• Primary producers are present in the first step of the food chain.
Primary producers are the first part of an ecosystem. They are the most important part of the ecosystem. They create the food base along with the decomposer. They are consumed by primary consumers; usually, herbivores and these primary consumers are then consumed by secondary consumers. An organism that lies at the top of the food chain dies, these organisms are consumed by the microorganism (decomposers). They help in fixing the nitrogen level and provide the organic material for the next generation of primary consumers.
