what is the only organisms on earth that can manufacture their own food?

The term you are looking for is "autotrophs."  The word means "self-feeders" and these types of organisms can synthesize their own energy-rich organic molecules.  They do not require any organic molecules from outside sources; only inorganic molecules.\nAutotrophs include plants and other photosynthetic organisms, and chemosynthetic bacteria (who form their food from chemicals).  \nAs a side note, heterotrophs are the organisms that cannot create their own food.\n\nHope this is helpful :-)

the answer is organic ... things that are organic are made from once living things.... vote me for best answer :) hehe jk you dont have to. hope i helped

What is in a biosphere? In a nutshell, every living thing.

protein, DNA, almost every cell in every living organism...so, basically, all of life itself.

Any life form as we know it could never live on Uranus. Of course, I think it's a bit arrogant and short-sighted to think that we know any and all forms that life can take. After all, life exists at the bottom of oceans where it was once thought living organisms could never survive. We have such a small perspective so far that there could be many forms of life that we can't currently imagine. Only time will tell.

The earliest living organisms were single-celled. They were prokaryotes, probably bacteria or archaea. They lived 3.8 billion years ago in the Eoarchean Era, a subdivision of the Archean Era.

what the hell kind of question is this? do you eat food or what? where do you get your food from? do you grow everything yourself?

Carbon containing compounds found in living organisms.  BTW, starches are just complex sugars.

A food web would go from the simplest form of life [the producer] to consumers. First draw the sun. Draw an arrow from the sun to a plant. Draw an arrow from the plant to an animal that eats it. Draw an arrow from the animal to an animal that eats the first animal. You can make it more complex and have more than one path of arrows.\n\nExample: Sun -> Grass -> Cow -> Human\n\nSun -> Grass -> Grasshopper -> Spider -> Bird\n\nYou can link these two.

Cell walls and photosynthesis.  You should know that not all bacteria carry out the ability to photosynthesize, but some do!  Those bacteria capable of photosynthesis share the feature with plants of being autotrophic; that is, they make their own food.

The metabolism of most living things involves creating energy or ATP from the catabolism of carbohydrates, primarily monosaccharides.   The primary source of carbohydrates in food comes from the plant kingdom.  Plants use the sun's energy to convert CO2 and H2O into carbohydrates.  So, indirectly the majority of energy produced by all living things originates from the energy of the sun.

All of them... or, none of them.\n\nIt all depends upon your notion of "facinating". \n\nCertainly humans have the ability to synthetically "adapt" temporarily to many environments, but there is also a plethora of creatures that are far more specialized than we:\n\nIce Worms live in glacial water\n\nSome tube worms live near ocean vents in amazingly extreme conditions, such animals have been found to transcend (near) boiling to (near) freezing water.\n\nArchaea is a bacteria group that has species which can live off of sulfur (or Iron, or such) and need no oxygen to survive.\n\nHyperthermophiles are another bacteria group within Archaea that survive in temperatures above 100 degrees C (~200 degrees F)\n\nThe Wood Frog, Rana sylvatica, can be Frozen solid (as in an ice cube) for months and survive the ordeal fine.\n\nWater Bears, Tardigrada, live in droplets of water and can survive for tens of years in a hibernate-like state \n\nI would bet this could be a very long list...

The ingredients to make life are quite simple. They (aminoacids, nukleotides, fattyacids, sugars) have been found on many off world places such as comets, meteorites and interstellar molecular clouds. Knowing that the ingredients are common and form easily they just need to be exposed to an energy source, like a star, while suspended in a medium (water) and exposed to catalysts (like clays rich in metallic oxides), that greatly speed things up, and eventually more and more complex substances will form. The magic ingredient is time. No God is required to make life, the planets or the universe. It took some 3.8 billion years for life to evolve from the primordial soup to us. Give me that much time to toy around and I´ll build you a staircase to the moon using nothing but a teaspoon.

A couple reasons, really.  First, all food chains begin with the plants that make their own energy from photosynthesis.  Without this step, there would only be a small amount of energy on the Earth, and with no way to replenish it, life would essentially cease to function.\n\nSecond, plants are the biggest converters of carbon dioxide to oxygen.  And trust me, that's kind of important.\n\nThird, nutrition.  Humans are omnivores, meaning they eat both plants and meat.  Without plants, the diet would be missing lots of essential nutrients.  Plus you run out of cows to eat when thay have nothing to graze on.

heterotrophs are the organisms that depend on other organisms for food.eg-human\nautotrophs are the organisms which can prepare their own food.

The unicellular organism is self sustaining. It can reproduce. The specialized cell cannot survive on its own. Take a blood cell for instance. It does important things for the body, but it can't make more blood cells, or a new person.

Most members of that kingdom are unicellular, but some are colonial and there are some that a simple multicellular.\n\nVolvox is a green alga and makes its own food, so it is an autotroph.  Radiolaria are heterotrophs.
