| Almost all producers capture energy from the sun and use it to make food throughPhotosynthesis. The reaction of Photosynthesis use the energy from sunlight to combine carbon dioxide and water to produce sugars. Nearly all the energy entering to Biosphere comes from Sun through Photosynthesis. |

The animals that eat only plants are Herbivores. Since Herbivores eat only plants
HERBIVORES = PRIMARY CONSUMERS |

Consumers that eat both producers nd consumers are Omnivores.
Omniovores act as Primary, Secondary and Tertiary consumers depending on what they eat. |

BActeria and fungi that consumes the bodies of dead organisms and other organic wastes are called decomposers.
They consume a variety of dead organic matter from the fallen leaves of a tree, to the bodies of Herbivores and Carnivores
Devomposers are crucial to the ecosystem because they recycle nutrients from organisms back to the environment. |

| Trophic levels are layers in the structure of feeding relationships in ecosystem. Producers make up the first level of and consumers make up several others trophic level. |

Definition
| The total amount of organic matter present in a trophic level. Biomass is potentially food for the next trophic level. Because of this scientist follow the transfer of energy from one to other trophic level by measuring Biomass |

Thorough the process of photosynthesis the plants consume CO2,water, and produce sugar and starch.When the living orginisms consume the nutrients they realese CO2 and waterto the atmosphere.Thi process is called carbon cycle.
