Terms in this set (21)
Producers assembling food molecules using energy from the sun
Producers assembling food molecules using energy-rich inorganic molecules
Primary producers that are organisms that synthesize food from inorganic substances by photosynthesis and chemosynthesis
The upper part of the ocean (the lighted zone where photosynthesis can take place)
Organism's metabolic rate ___ with increased temperature
Can cold or warm water hold more gas in solution?
A ____ is a group of organisms that interacts in a specific place
One of the largest ocean communities, lives suspended in the water
not a collective natural category; it is a description of a lifestyle. The plankton include many plantlike species and nearly every major group of animals.
organisms drift or swim weakly
Organisms that swim freely
The most productive plantlike organisms that make up the phytoplankton
Important nektonic animals
include cephalopods, shrimps, fishes, seabirds, and marine mammals. Each has a continuously evolving suite of adaptations that allows it to meet the challenges of the marine environment.
divided into two major groups based on the material forming their skeletons.
indicators of oceanic productivity, and are second only to marine mammals in consumption of large planktonic crustacea
organisms that live on or in the ocean bottom. Their distribution is rarely random; clumped distribution is the most common
Carbohydrates produced by these highly productive large algae (and the vascular plants) can provide much of the energy needed by animals of the benthic communities.
high-energy rock and sandy shores
heavily populated by diverse organisms able to take advantage of the abundant feeding opportunities found there.
Coral reef communities
exceptions to the general rule that tropical oceans are unproductive. Closely cycled nutrients and the specialized dinoflagellates in coral organisms make high productivity, and high species diversity, possible.
a large group of flagellate protists. Most are marine plankton, but they are common in fresh water habitats as well.
Coccospheres shown note individual coccoliths widespread in today's oceans, especially in temperate zone "spring blooms" and are main group in central gyre regions prefer low to moderate nutrient supply. They are the thing that grow like crazy in April in the beiring sea. They are the reason why krill will go there to eat. Theyre the reason why whales will go to swim there at the right time.
