Producers: Organisms which convert some of the energy from the sun into stored chemical energy (usually plants).
Primary consumers: Organisms that obtain energy by consuming producers. They are herbivores.
The ?rst level in a food pyramid; consist of organisms that generate the food used by all other organisms in the ecosystem; usually consist of plants making food by photosynthesis.
producers organisms within an ecosystem that trap energy (by photosynthesis).
progesterone a hormone produced by the corpus luteum that regulates the buildup of tissue in the endometrium and inhibits the contractions of the uterus.
The in this ecosystem are planktonic algae.
The primary consumers include such animals as microscopic crustaceans and rotifers - the so-called zooplankton.
The secondary (and higher) consumers are swimming insects and fish.
With over 30 countries producing silk the major producers are:
Japan (11%) ...
receive their energy from light energy (the sun) by means of photosynthesis. After this, the energy in organic matter flows from to primary consumers to secondary consumers to tertiary consumers.
Producers then recycle these elements into organic compounds.
An ecosystem's main decomposers are fungi and prokaryotes.

-- plants which are capable of photosynthesis
consumers -- animals, which can be primary consumers (herbivorous), or secondary or tertiary consumers (carnivorous).
Producers, a major niche in all ecosystems, are autotrophic, usually photosynthetic, organisms. In terrestrial ecosystems, producers are usually green plants. Freshwater and marine ecosystems frequently have algae as the dominant producers.
Organisms, such as plants, able to produce their own food from inorganic substances.
production frontier The maximum output of two competing commodities at different levels of production.

Now down the bottom are are the phytoplanktons and the vegetation that's either in or around the water. Now you can see they're being eaten by these herbivores the primary consumers and then those are being eaten by the secondary consumers.
Cyanobacteria remained principal primary producers throughout the Proterozoic Eon (2500-543 Ma), in part because the redox structure of the oceans favored photoautotrophs capable of nitrogen fixation.
The (autotrophs) are those organisms which can synthesize their own biomolecules and enough for the consumers, too. The consumers (heterotrophs) such as us and other animals, rely on the metabolic capabilities of the .
In competitive situations, sexual reproduction is a better strategy because sexually reproducing species evolve at a faster rate, giving the sexual reproducers an advantage over asexually reproducing competitors.
Chloroplasts are the food of the cell. They are only found in plant cells and some protists. Animal cells do not have chloroplasts. Every green plant you see is working to convert the energy of the sun into sugars.
Green organisms such as plants (called producers) capture solar energy. Some of the energy is used for maintenance, growth, reproduction or other needs. Some is stored in chemical compounds and some is lost as heat.

These cells were called producers. Producers evolved the ability to actually create their own food, using the chemicals around them, and the energy from the Sun, or from heat found in the Earth. These producers would be ancestors to the plants ...
Primary capture energy from the environment (through photo- or chemo-synthesis) and form the base of the food chain.
primary consumers - herbivores that feed on producers
secondary consumers - consumers that feed on primary consumers and/or producers
tertiary consumers - consumers that feed on secondary and primary consumers, as well as on producers ...
The role of phytoplankton is better understood due to their critical position as the most numerous primary on Earth.
The gross primary productivity minus the energy used by the producers for cellular respiration; represents the storage of chemical energy in an ecosystem available to consumers.
net productivity ...

Secondary production: The biomass production resulting from the assimilation of organic matter produced by a primary consumer; production by organisms (mainly animals) which consume primary producers (mainly plants).
