Most autotrophs use sunlight in the process of photosynthesis to make

Photosynthesis is the name of the process by which autotrophs (self-feeders) convert water,

The most common are the photosynthetic autotrophs or photoautotrophs, who use energy from sunlight (2, 4). Carbon dioxide from the air is their source of carbon. In a process called photosynthesis, energy from the sun is used to combine carbon with water to give carbohydrates (4, 6). The first product is glucose, a simple sugar (4, 6). These sugars are later used to produce starch, cellulose, amino acids, and other organic compounds that the organisms need (4). The chemical reaction that occurs is,

Autotrophs need the sun to produce energy.Heterotrophs are herbivores, omnivores and carnivores.

Similarities
between Heterotrophs and Autotrophs


For Photosynthesis to occur there must be :
- Sunlight
-Water and
- Carbon dioxide
These are the inputs for photosynthesis

The outputs for photosynthesis are:
-Glcose and
- Oxygen
These images show the inputs and outputs of photosynthesis
This images shows the equation for photosynthesis
Heterotrophs cannot create their own food and must rely on other organisms ,both plants and animals, for nutrition and food.


Why is photosynthesis important to autotrophs

These distinctions are important because of the way they affect the carbon cycle. In the carbon cycle carbon is transformed by photosynthetic organisms from inorganic forms (mainly CO2 to organic forms (usually glucose), then - by phototrophic and heterotrophic bacteria - among many different organic carbon forms. Ultimately heterotrophic bacteria (and other heterotrophic organisms) return carbon to its most common inorganic form, CO2.

What are some examples of autotrophs or heterotrophs?

Autotrophs make the organic carbon molecules (for cellular matter and energy storage) from inorganic raw materials: CO2. Heterotrophs rely on organic carbon molecules (provided, ultimately, by autotrophs) for energy and cell-building. Because photosynthesis yields both energy and organic carbon from sunlight and CO2 phototrophs are also autotrophs (often called photoautotrophs). Chemotrophs are usually heterotrophic, but some species of bacteria exist than can acquire energy from inorganic chemicals.

Heterotrophs and Autotrophs by Reannon Craig on Prezi

As their name indicates, they use light for energy, and their carbon source is ready organic compounds like carbohydrates, fatty acids and alcohol (1). Then similar to autotrophs these heterotrophs also manufacture their own food (2). Purple non sulphur bacteria, green non-sulphur bacteria and heliobacteria are examples of photoheterotrophs (1).
