Answer 1

the answer to your question is B

Answer 2

Answer:

in a lake ecosystem, the pyramid of biomass is inverted. This is because in a lake, the primary source of food is the planktons and algae. These are eaten by the smaller fishes, which in turn get eaten by the larger fishes.

The larger fishes are ultimately eaten by the bigger birds leaving around the lake. Thus the highest level in the pyramid has the highest biomass, compared to the base levels. hence it is inverted.
