Organisms that obtain energy by taking in food are called?
heterotrophs
Are vegetarians the only heterotrophs that get all their energy from plants?
No, vegetarians, or better described, as herbivores in this example, are not the only heterotrophs that get all their energy from plants. All living organisms, including carnivores, also derive energy from plants by eating the herbivores.
Compare the metabolism of autotrophs with that of heterotrophs?
Heterotrophs are organisms that cannot manufacture its ownfood and instead obtains its food and ernegy by taking in organic substances,ussually plant or animal matter.eg of those organisms are:all animals,protozoans,fungi,and bacteria. Autotrophs is an organism that manufacter its own food from inorganic substances such as Carbondioxied and ammonia.eg of those organisms are green plants,certain algae,photosythetic bacteria.
Is anabaena autotroph or heterotroph?
Ameba is heterotrophic.Autotrophs (from Greek autos = self, trophe = nutrition) make their own food by taking energy from the environment (sun light or other chemicals). These include plants and algae or anything with chlorophyll.Heterotrophs (from Greek heteros = other, trophe = nutrition) get their energy by eating other living things. Ameba is a heterotroph since it eats smaller animals and plants.
What simple organisms are able to carry on photosynthesis in each cell?
No, not all living organisms undergo photosynthesis. Only phototrophs (photosynthetic autotrophs) such as plants, algae, and many forms of photosynthetic bacteria undergo photosynthesis. All other organisms live by eating autotrophs or other organisms that have eaten autotrophs; these organisms are heterotrophs. There are a few specialized organisms (which may live where no light shines) that use a process called chemosynthesis to get their energy; these organisms are called chemotrophs.

heterotrophs
Does bacteriamake its own food?
Some bacteria, called autotrophs, make their own food from the carbon in CO2. Most bacteria are heterotrophs, taking their food 'ready-made' from other sources.
How do you differentiate autotrophs from heterotrophs?
Heterotrophs came first because they could live off the minerals in the oceans (Heterotrophs are just organisms that take their source of energy from somewhere else - minerals do count). Autotrophs, however, could not have lived first because the ozone layer was not formed, and taking in the sunlight would have been the same as taking in harmful UV radiation that would have killed the autotrophs. The cyanobacteria (which are heterotrophs) were the ones that first helped create the ozone layer.Actually, Cyanobacteria aren't heterotrophic. This WRONG answer led me cramming for our debate about Autotrophs vs. Heterotrophs. If you want to know about which came first, either search about primordial theory by A.I Oparin or go to http://leiwenwu.tripod.com/(:my yahoomail: lord_reverie@yahoo.com.ph

What is a Non examples of biomass?
All non-organic is non-biomass and thus the "not the example of biomass". For example, your tennis racket made of graphite and not the biomass, your wall is concretes and not the biomass and your glass windows is definitely made of glass and not the biomass (not taking account of the wood frame though).

Why is biomass a better alternative than coal?
The main advantage of biomass over coal is that it is "carbon neutral". This means that in order for the biomass to be created, it consumed carbon dioxide from the environment. Upon burning biomass, no additional carbon is added to our atmosphere. Coal, on the other hand, is taking carbon out of the earth and adding more to our atmosphere.
What is a biomass piramid?
An ecological pyramid of biomass shows the relationship between biomass and trophic level by quantifying the amount of biomass present at each trophic level of an ecological community at a particular moment in time. It is a graphical representation of biomass(total amount of living or organic matter in an ecosystem) present in unit area in different tropic levels. Typical units for a biomass pyramid could be grams per meter2, or calories per meter2.The pyramid of biomass may be 'inverted'. For example, in a pond ecosystem, the standing crop of phytoplankton, the major producers, at any given point will be lower than the mass of the heterotrophs, such as fish and insects. This is explained as the phytoplankton reproduce very quickly, but have much shorter individual lives.One problem with biomass pyramids is that they can make a trophic level look like it contains more energy than it actually does. For example, all birds have beaks and skeletons, which despite taking up mass are not eaten by the next trophic level. In a pyramid of biomass the skeletons and beaks would still be quantified even though they do not contribute to the overall flow of energy.(This is copied from Wikipedia)
What is the taking in of food called?
The process of eating is a form of consuming, or consumption. All heterotrophs (consumers) must consume other organisms to survive, whereas autotrophs (producers) create organic material from inorganic matter (water, air, minerals) using energy from light, sunlight, or much more rarely thermal sources.
