The primary product of production is ______, and it is measured in _____.
Carbohydrate, grams of carbon per square meter per year.
Biomass means _____. Standing crop is the _____ in an ecosystem.
mass of living tissue, mass of living tissue at a given time
Primary production of land is higher than the primary production of the sea.
A wide variety of organisms that share a common habitat and lifestyle. They all float or are too weak to swim against the current.
Most production in the sea comes from...
plant-like protist that causes red tide. Characterized by two or more whip-like flagella that aide in food capture and movement. Also found in coral polyps.
microscopic algae with calcium carbonate shells, form the base of many marine food webs. This plankton causes a milky white bloom in the ocean.
very small plankton; includes bacterioplankton and cyanobacteria
Represents the distribution of biomass among trophic levels showing how energy transfers from one level to the next.
An organism that eats producers
An organism that eats primary consumers
The amount of energy transferred from one trophic level to another.
a system of interlocking and interdependent food chains.
Food webs represent the flow of energy better than a trophic pyramid because...
organisms often eat across multiple trophic levels.
Is necessary for life as inorganic compounds are recycled and returned to the producers this way.
Some archaea and bacteria
can photosynthesize, are found in the millions in a liter of seawater, can live in extreme environments, and are responsible for most oxygen in the atmosphere.
Percent of carbohydrate produced by diatoms in the phytoplankton realm.
Large brown seaweed. It is multicellular unlike the diatoms who are unicellular.
chlorophyll a and chlorophyll b
two types of chlorophyll
A type of yellow-green accessory photosynthetic pigment that transfers energy to chlorophyll a. ACTIVELY involved in photosynthesis.
Red algae can live deeper than other algae because they produce cellulose, which resists water pressure better.
False. It is because of the pigment that traps blue light.
Red algae are important to coral reefs because
they help cement the reef together
The presence of chlorophyll a and b in green algae lead some scientists to think that
land plants evolved from algae.
The greatest problem with plants living in the ocean is
A unicellular photosynthetic alga with a unique glassy cell wall containing silica
Filamentous green algae
