Detail about MCQs

The ecological pyramid always starts with producers at the base. Producers, such as green plants, algae, and certain bacteria, are organisms capable of photosynthesis or chemosynthesis, through which they can convert energy from sunlight or inorganic compounds into organic matter. They form the foundation of ecosystems by producing organic compounds that serve as food for other organisms in higher trophic levels. Therefore, producers occupy the lowest level of the ecological pyramid, followed by primary consumers (herbivores), secondary consumers (carnivores or omnivores), and so on, with decomposers typically occupying the final level.
