IV. Biomass,
Energy, and Ecosystem
Structure
terms: biomass,
wet vs. dry
weight, dry
organic matter,
standing
stock
a) The Distribution of Biomass among
Plants, Herbivores,
and Carnivores
terms: pyramid
of biomass, pyramid
of energy,
pyramid
of numbers
b) Energy Flow - A Key to Inverted Pyramids
RQ 11.1 (Fig. 11.9): Explain
why the Black Sea has an
inverted pyramid of biomass, whereas the tropical
Pacific epiplankton does not.
Case History: High Tech in Deep Space
Description of Research Vessel - Pt. Lobos at MBARI Website
I. Life at the Open Sea Surface
terms: compensation
depth, critical depth, spring
bloom
a) The Standard Cold-temperate Ocean
RQ 13.1: Describe annual
patterns of productivity in the North
Atlantic, bringing
the terms compensation depth and critical
depth into the
description.
b) The Seasonal Cycles in Other Oceans
RQ 13.2: Describe annual patterns
of productivity in the Sargasso
Sea, bringing
the terms compensation depth and critical
depth into the
description.
c) The Annual Productivities of Oceanic
Communities
terms: net
primary productivity (NPP),
eutrophic,
oligotrophic
RQ 13.3: Contrast the following
habitats in terms of the "apple
index" used in Fig. 13.4 (equivalent amount of carbon
in apples per square meter per year): tropical rain forest,
cropland, desert, rocky intertidal, open ocean, kelp bed,
coral reef.
II. Communities in the Deep Sea
a) Life in Deep Open Water
b) The Bottom of the Sea
1) The abyssal
seafloor is sustained by the arrival of
food from the surface
RQ 13.4: What sorts of organisms
are found on a typical
ocean
bottom and what do they feed on? What limits their
abundance?
2) Hydrothermal
vents support communities unlike any
other on Earth
terms: hydrothermal
vents, black
smokers, seeps, trophosome

RQ 13.5: Explain why life is so abundant around hydrothermal vents.
RQ 13.6: How do the giant
pogonophoran
tubeworms around
hydrothermal
vents derive their energy?
Featured
organisms: hot-vent
pogonophoran tubeworms
