Ecology
In a trophic cascade where top predators are removed from an ecosystem, what could be a potential outcome on the carbon cycle at the ecosystem level?
When studies show that biomass accumulation can decrease at higher trophic levels but also reveal certain predators can stimulate plant growth via herbivore regulation, which outcome complexly integrates these principles?
In an aquatic ecosystem, what would most likely happen if a toxin selectively killed keystone predatory fish?
What feature of a leaf's structure most directly facilitates efficient energy capture in an ecosystem?
If a volcanic eruption introduces a significant amount of ash into an aquatic ecosystem, disrupting light penetration and primary productivity, what immediate effect could this have on the carbon cycle within this ecosystem?
If a forest ecosystem exhibits high primary productivity but low net primary productivity (NPP), what could be a plausible explanation?
How does bioaccumulation affect higher trophic levels in a food chain?

In a food web consisting of grass, grasshoppers, frogs, and snakes, which trophic level would exhibit the greatest loss of usable energy in the form of heat during cellular respiration?
What long-term effect might the introduction of non-native decomposer species have upon an established temperate forest's nutrient cycles, particularly the phosphorus cycle?
What would be an unexpected long-term consequence for terrestrial plants if mycorrhizal fungi were suddenly absent from soils rich with decomposers like bacteria and earthworms?
