What might cause red tides?
increase in nutrients in the water.
increase in oxygen in the water.

What type of ecological pyramid is never inverted?
ecological pyramid
energy pyramid
numbers pyramid
biomass pyramid
Which of the following would result in an inverted biomass pyramid?
A grassland ecosystem with a small number of herbivores
A lush rainforest with hundreds of herbivores
A marine ecosystem with more zooplankton than phytoplankton
A swamp ecosystem with hundreds of frogs
What does a biomass pyramid compare?
the amount of biomass at each trophic level
the amount of energy available at each trophic level
the amount of biomass consumed at each trophic level
the amount of individuals at each trophic level
Why are energy pyramids never inverted?
because energy is always lost from one trophic level to the next
because energy is always gained from one trophic level to the next
because energy cannot be measured as it transfers from one trophic level to the next
because it just never is
