This type of pyramid is usually found in the grassland ecosystem and the pond ecosystem.

Consider the following statements about the pyramid of numbers - uprig...
Explanation:
Pyramid of numbers is a graphical representation of the number of organisms at each trophic level in an ecosystem. It can be upright or inverted depending on the ecosystem.
1. The number of individuals decreases from lower level to higher trophic level.
This statement is correct. The number of individuals decreases from lower trophic levels to higher trophic levels. This is because energy is lost at each trophic level due to respiration, heat loss, and incomplete digestion. Therefore, fewer organisms can be supported at higher trophic levels.
2. Grasses occupy the lowest trophic level because of their biomass.
This statement is incorrect. The lowest trophic level is occupied by producers, which are usually plants. Grasses may be a common example of a producer, but other plants such as algae, phytoplankton, and trees can also occupy this level. The reason for their position in the pyramid is not their biomass, but their ability to convert sunlight into energy through photosynthesis.
In conclusion, option B is the correct answer as statement 2 is incorrect.
