Exam 12: The Plankton, Energy, and Food Webs

A standing crop of phytoplankton can be measured by

Greater mixing and nutrients from the land cause the coastal areas to generally have higher primary productivity than the open ocean.

The only zone of the ocean with sufficient light for photosynthesis is the

Harmful Algal Blooms (HABs) are always associated with toxins.

Primary productivity is measured in terms of gC/m²/day.

Although light, nitrogen and phosphorous are abundant in the Pacific and Southern Oceans the plankton are less abundant due to

Holoplankton spend only their larval stages in the plankton.

Plankton that range between 200 microns and 2mm in size are considered

At low (tropical) latitudes, phytoplankton blooms are typically most limited by

Comb jelly is another name for jellyfish.

One of the most abundant groups of microorganism on the planet are

Adding iron to the surface of the ocean has been shown to

Chlorophyll a absorbs energy mostly in the blue and red wavelengths.

Larval stages of starfish, barnacles, and crabs belong to the

Approximately 15% of the world's ocean area produces 85% of the ocean's harvest.

Some phytoplankton species migrate as much as 500m vertically every day.

At higher and higher trophic levels, there are usually _____ and _______ animals.

If the net primary production in a region is continually consumed by herbivores, the standing stock

The arctic region has low annual productivity because

In temperate waters, the timing of the phytoplankton bloom is influenced by
