(A) and (D) only
Detailed Explanation
An inverted pyramid of numbers can be seen in an ecosystem where the population includes a few very big biomass suppliers that benefit a greater number of smaller consumers. Thus, the number pyramid in the tree ecosystem will be inverted as the first trophic level, that is, the tree, is the least in number in the ecosystem. The pyramid of biomass in sea is generally inverted because the biomass of fishes far exceeds that of phytoplankton.
