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.
