Explanation:
Green plants (producers) always occupy the first trophic level in a food chain. Energy flow is unidirectional, moving from the sun to producers and then to consumers, never returning to the sun. Due to the 10% law of energy transfer, the pyramid of energy is always upright and can never be inverted. Thus, statements 1 and 2 are correct.

Explanation:
The cell wall of fungi is primarily composed of chitin, a tough, complex polysaccharide also known as fungal cellulose. This distinguishes them from plants, whose cell walls are made of cellulose, and bacteria, whose cell walls contain peptidoglycan. Chitin provides structural support and protection to fungal cells.

Explanation:
Apis cerana indica (the Indian honeybee) is the most commonly domesticated species for commercial apiculture (beekeeping) in India. It is well-adapted to the local climate and is less aggressive than Apis dorsata (the rock bee). Apis mellifera (the Italian bee) is also widely used globally and in India for its high honey yield and gentle nature. Apis florea is the little bee, which is not suitable for commercial beekeeping.
