Both statements are correct.
1. In a pyramid of biomass, the weight (biomass) of all individuals in each trophic level is considered instead of counting the number of individuals. This gives a more accurate representation of the energy available in each trophic level, as larger organisms typically have more energy stored in their tissues.
2. The pyramid of biomass is structured with producers at the bottom, representing the largest amount of biomass in the ecosystem. Producers (e.g., plants) convert sunlight into energy through photosynthesis and form the base of the food chain. As energy transfers up the trophic levels through consumption, energy is lost in the form of waste and heat, resulting in a decrease in biomass as you move up the pyramid. This is why the biomass of producers is at the bottom of the pyramid, as they represent the largest amount of available energy in the ecosystem.

Explanation:
Pyramid of biomass is a graphical representation of the amount of biomass (total dry weight of all living organisms) present in each trophic level of an ecosystem.
1. Individuals in his trophic level are weighed instead of being counted:
This statement is correct. The pyramid of biomass is based on the dry weight of organisms in each trophic level, rather than the number of organisms. This is because the weight of an individual organism can vary greatly within a trophic level, and using the number of individuals would not accurately represent the amount of energy available at each level.
2. The Biomass of producers is at the bottom:
This statement is also correct. The pyramid of biomass is always upright, with the largest biomass at the base of the pyramid and the smallest biomass at the top. This is because energy is lost at each trophic level due to respiration, heat loss, and incomplete digestion, so there is less biomass available to support higher trophic levels. Therefore, the producers, which are the base of the food chain, have the largest biomass.
Therefore, both statements are correct, and the correct answer is option C - Both 1 and 2.
