A. The most abundant animals are typically found at the **producer level** (such as herbivores) in terrestrial ecosystems or nearby the **primary consumer level** in aquatic ecosystems. In general, the distribution of species abundance often shows that primary consumers (herbivores) are more abundant than secondary or tertiary consumers (carnivores).
B. The least common animals are usually found at the **tertiary consumer level** or apex predators in the food chain. These animals are fewer in number as they rely on a larger base of primary and secondary consumers for food.
C. The fundamental reason for these answers lies in the **energy pyramid** concept. In ecological terms, energy diminishes as you move up trophic levels due to energy loss in the form of heat (e.g., through metabolic processes), waste, and inefficiencies in energy transfer (only about 10% of energy is typically transferred from one trophic level to the next). Hence, there are more organisms at the lower levels (such as producers and primary consumers) as they have the highest energy availability, while higher trophic levels, which depend on many lower trophic levels for sustenance, have fewer individuals due to limited energy availability.
