Radiant energy to biomass
The sun yeilds radiant energy that the producers use to perform photosythesis. The producer then uses the stored energy to convert it into chemical energy in the form of glucose.
How does radiant energy become biomass?
Examples
Types of biomass include wood, crops, landfill gasses

More information
More info
The chemical energy is passed on to people and animals that consume the plant matter. The chemical energy from biomass is released as heat when burned.
The Law of Conservation of Energy
"Energy cannot be created nor destroyed; rather, it can only be transformed from one form to another."
The Law
Metabolic process
In the metabolic processes the chloroplasts in the producers cells take in ( the reactants) carbon dioxide, H2O (water), sunlight (energy), and the products are glucose and oxygen. Then the mitochondria uses the glucose and the oxygen to transform the nutrients into carbon dioxide, water, and ATP.
Metabolic process
Photosynthesis
Photosynthsis is a process where plants create their own food using sunlight. Plants absorb H2O (water) through their roots in the soil and storing it within their cells. When the sunlight hits the water molecules, the water breaks apart into hydrogen and oxygen. Plants also take CO2 in through holes called stomata. This is a plant's way of breathing. When the carbon dioxide combines with hydrogen, a type pf sugar called glucose is formed.
Photosynthesis
The Energy
It is estimated that only 10% of energy/tissues are absorbed/consumed by an organism is transferred to the next trophic level (a trophic level is a level an organism occupies in a food chain). For example, a herbivore (2nd trophic level) will 90% of it's available energy for metabolic process, leaving 10% to be passed on to the carnivore (3rd trophic level) when the herbivore is consumed. Each time energy is transferred, some is released in the atmosphere as heat. This results in onle a fraction of solar energy absorbed by producers to reach apex predators.The omnivores eat both plants and animals.Then there are the recyclers or decomposers that "recycle" the dead biomass.
