We explain what are the producing organisms, their classification and examples. In addition, consuming and decomposing organisms.
Producing organisms , also called autotrophs (from the Greek auto that means “by itself” and tropes that means “nutrition”), are beings that produce their own food from inorganic substances such as light, water and carbon dioxide , so they don’t need other living things to nourish themselves.
Producing organisms keep the planet in balance because they are the main source of food and provide all the nutrients to primary consumers, generate oxygen and provide numerous gases that make up the atmosphere .
Examples of producing organisms
Some examples of producing organisms are:
- The colored bacteria .
- The grass.
- The weeping willow.
- The olive tree
- The bushes
- The seaweed coleochaete.
- Some microorganisms .
Types of producer organisms
Producing organisms are classified into two types, according to the source of energy they use:
- Photosynthetics They are the organisms that make the conversion of inorganic matter into organic by a process of synthesis of the energy provided by sunlight . That process is called photosynthesis . For example, plants that have chlorophyll such as asparagus, parsley.
- Chemosynthetics They are the organisms that obtain energy from the oxidation of inorganic compounds such as iron, hydrogen, sulfur and nitrogen. For example, nitrogen bacteria that come into contact with ammonia, transform it into nitrates that can be used by plants.
Producing organisms are the initial link in the food chain , which is made up of three groups of organisms:
- The producers.
- The consumers.
- The decomposers
The consuming organisms, also called heterotrophs (from the Greek hetero that means “different” and trophos that means “nutrition”) feed on organic matter , that is, other plant and / or animal living things. Within the food chain, consumer organizations are divided into:
- Primary consumers They are herbivorous animals that feed on different parts of plants such as leaves, stems, roots, seeds or substances made by the plant. Some examples of primary consumers are the goat, the cow, the cricket, the sheep, the bat, the hummingbird and the gorilla.
- Secondary consumers They are carnivorous animals that are classified into different types, such as predators (that hunt other animals), parasites (that feed on others, but not kill them) and scavengers (that feed on the remains of other animals). Examples of secondary consumers are the lion , the shark, the wolf, the polar bear and the dolphins.
- Tertiary consumers Also called omnivores , they are animals that feed on secondary and primary consumers. For example, the piranha, the rat, the hedgehog, the human being , the dog, the seal, the panda, the raccoon, the hyena and the wild boar.
Decomposing organisms are those that harness the energy of decomposing organic matter , that is, the remains of vegetables and animals. These organisms convert the remains into inorganic energy that is then used by the producing organisms. Some examples of decomposing organisms are:
- The insects. For example: the spider, acari and diptera.
- Bacteria . For example: azotobacter and pseudomone.
- Fungi For example: shiitake and water mold.
