Transcript of Heterotrophs and Autotrophs

Autotroph
An autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances, such as carbon dioxide or water.
Autotrophs are substances that soak up light.
Some examples are plants and algae.
Autotrophs need sunlight to gain energy.
Autotrophs are knows as 'produces'.
Photosynthesis
Differences
between Heterotrophs and Auotrophs
Autotrophs are organisms that can make energy-containing organic molecules from inorganic materials by using energy sources such as sunlight.
Some similarities between Heterotropths and Autotrophs are:
They are both living things
They both need food to live
They both need air, water and sunlight to live
Both Autotrophs and Heteroptrophs convert small molecules into large molecules during the preparation of food.

Heterotrophs and Autotrophs
Heterotroph
A heterotroph is an organism that
obtains the energy for living or nutritional requirements from complex organic matter. They obtain this matter from their surroundings, as they are not able to make their own food.
Heterotrphs are knows as 'consumers', as they eat Autotrophs ( the produces)
Heterotorphs are animals, fungi, bacteria and some single celled protozoa.
Autotrophs gain their energy from the sun. This process is called Photosynthesis.
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.
Autotrophs are plants, algae and some bacteria. Autotrophs need the sun to produce energy.
Heterotrophs are herbivores, omnivores and carnivores. These characteristic can be fond in animals, fungi, bacteria and humans, as well as some single-celled protozoa and some algae.
Autotrophs produce their own food for energy
Heterotrophs eat other organisms
to get proteins and energy needed
for life and proper functioning

between Heterotrophs and Autotrophs
