  Heterotroph
Some parasitic plants have also turned fully or partially heterotrophic, whereas carnivorous plants use their flesh diet to augment their nitrogen supply, but are still autotrophic.
Heterotrophs are unable to synthesize organic, carbon based compounds independently from the inorganic environment's sources (e.g.
In simpler terminology, a heterotroph is an organism that is incapable of making its own food from light or inorganic compounds, and feeds on organisms or the remains of other organisms to get its necessary energy to survive.

 Heterotroph Summary
Heterotrophs (from Greek heteros = other or different, trophos = feeder) are organisms that are not able to make their own food.
Heterotrophic microorganisms mostly feed upon dead plants and animals, and are known as decomposers.
Heterotrophic bacteria, therefore, are largely responsible for the process of organic matter decomposition.

These cells were heterotrophs, which could not produce their own food and instead fed on the organic material from the primordial soup.
The few heterotrophs that survived the change in environment generally evolved the capacity to carry out aerobic respiration.
Over the subsequent billions of years, the aerobic autotrophs and heterotrophs became the dominant life-forms on the planet and evolved into all of the diversity of life now visible on Earth.

Heterotrophs are the consumers of the food chain.
This process of producing biological energy is different from that of autotrophs who produce their own food using energy from the Sun.

 GREEN WATER:
When algae dies and is subjected to aerobic bacterial decomposition by heterotroph bacteria, a by-product of this process is a substance, released into the water, that is toxic to the living algae.
The nitrification bacteria are consuming the molecular particles of ammonia and nitrite and the heterotrophs are working on many other types of organic matter as well as the dead algae cells.
During the frequent backwashing processes, however, the dead algae and much of the heterotroph bacterial colonies are removed from the system giving insufficient time for the antibiotic to be produced.

 Evolution   (Site not responding. Last check: 2007-10-01)
Heterotrophs with flagella probably evolved from one heterotrophic prot-amoeba organism (as most heterotrophs did) which eventually developed into the flagellate ancestor.
Heterotrophs in general played a key roll in the evolution into multicellular organisms.
Phylogenetically, the heterotrophic groups of the Protist kingdom may have shared one common ancestor, but had different path of evolution into what organisms they are today.

Heterotrophs are considered organisms that cannot produce their own food, therefore they eat other organisms that CAN produce their own food (called autotrophic).
Heterotrophs with flagella encompass 2 classes of protists: sarcomastigophora (flagellates) and ciliophora (ciliates)
The second class of heterotrophs with flagella, (we will refer to them as the ciliates), is considered the most complex group of protists.

 Energy and Human Evolution   (Site not responding. Last check: 2007-10-01)
The first living things may have obtained energy from organic molecules that had accumulated in their environment, but photosynthetic autotrophs, able to capture energy from sunlight, soon evolved, making it possible for life to escape this limited niche.
The existence of autotrophs made a place for heterotrophs, which use energy that has already been captured by autotrophs.
Humans are the most recent in the series of heterotrophs that use increasing amounts of energy, but they differ from other species in this lineup in their ability to use more energy without further speciation.

 Autotrophs and Heterotrophs
Editor's Note: The heterotrophs are those who feed from pranic energy from breathing and from water and animal and/or vegetable food that digest in their stomachs.
The only pranic energy is not enough to maintain alive a heterotroph person, likewise the only food and water are neither enough to maintain the heterotroph alive since he or she need breathing.
The autotrophs are people that only feed from pranic energy and live a healthy and active life.

 Re: heterotroph or autotroph?
These aggregates (also known as coacervates) incorporated molecules from the ocean as food.
The respiration of the heterotrophs must have been anaerobic as there was little or no oxygen in the atmosphere at the time.
Some of the heterotrophic aggregates developed a method of using carbon dioxide to manufacture their own food, and so became pioneer autotrophs.

This research highlights the need to understand interactions between unicellular algae, heterotrophic microbes and the protozoa that consume them in order to more fully comprehend and model carbon cycling.
We are pursuing three interlinked research areas in order to develop a mechanistic understanding of microbial contributions to global carbon cycling: molecular underpinnings of microbe-microbe interactions; competition processes/trophic linkages (the bases of food web dynamics); and quantitative, mechanistic models of functional diversity, primary production and trophic transfer in marine environments.
I am a member of a team of collaborators from Ghent University, the Station Biologique Roscoff, and Laboratoire Arago at Banyuls sur Mer who are completing annotation of the genome of Ostreococcus tauri, a tiny, but important marine photosynthetic eukaryote discovered 10 years ago.

Given a graphic organizer depicting the Heterotroph Hypothesis, the learner will be able to accurately explain, in written form, why evolutionists believe that life began as a one-celled organism and evolved into a complex organism.
As the Heterotroph Hypothesis is being presented, the educator should informally ask questions of the students to assess their level of knowledge.
After the material has been covered, students should be able to provide the educator with a series of pictures representing the events that are believed to have occurred on earth.

One theory about the extinction of dinosaurs is that the collision of an asteroid with the Earth caused environmental changes that killed off the dinosaurs in a relatively short time, changing the course of evolution.
One assumption about the environment of the primitive Earth, as stated in the heterotroph hypothesis, is illustrated in the diagram below.
According to the heterotroph hypothesis, some early heterotrophs evolved into autotrophs because of their ability to synthesize organic compounds from water and
