Answer 1

ANSWER

In pond ecosystem, the shape of pyramid of number is always upright. It represents the number of individuals at each trophic level. In this, the energy is maximum at producer level, followed by primary consumer level (herbivores), followed by secondary consumer level (carnivores). The base of the pyramid of number represents the producers in a pond ecosystem. 

Thus, the correct answer is 'Upright'.
