When describing the biomass difference between an acorn and an oak tree, it is most accurate to describe

A simple aquatic food web has phytoplankton, zooplankton, shrimp, and redfish. The productivity values are 200 g/m2for phytoplankton, 40 g/ m2 for zooplankton, 4 g/ m2 for shrimp and 0.5 g/ m2 for redfish. What is the trophic level transfer efficiency from zooplankton to shrimp?

Imagine Community 1: 5 species, one dominant species (e.g., 70 individuals), others rare (e.g., 5-10 each). Community 2: 5 species, each with roughly equal abundance (e.g., 20 individuals each).

A key exception to the Species-Productivity Hypothesis is:

After a volcanic eruption, the colonization of the area that was covered by the lava from the eruption is best described as:
