COMMUNITIES AND ECOSYSTEMS
Matter and the First law of thermodynamics
First law of thermodynamic
"Energy is not created or destroyed, it is only transformed".
Matter and energy
Move from primary producers to consumers and saprophages through food chains.
Saprophages
The organisms that feed on dead matter.
Disintegrators
Consume and degrade dead matter by non-digestive enzymatic mechanisms.
Detritivores
Detritivores consume and degrade dead matter through the digestive tract.
Producers
All organisms that produce tissues from photosynthesis, chemosynthesis, or food consumption.
Secondary producers
Consumers
Tertiary
Predators
Secondary
Parasites
Carnivores
Primary
Hervibores
They are heterotrophs, produce tissues from the feeding of the bodies or products.
Primary producers
Are those who make their own food from photosynthesis and chemosynthesis, they are autotrophs.
Food web or trophic network
The set of interwoven food chain, which is how populations within the ecosystem are related.
Thropic level
Is the number of times by which food energy passes from one living being to another.
Food chain or throphic chain
The linear scheme in which food passes from are organism to another.
Basic knowledge
The way in which matter and energy are transformed between biotic and abiotic factors is food.
An ecosystem is made up of different biotic and abiotic comportments through which matter and energy pass.
