Decomposers which are not bacteria

Unlike bacteria and fungi, these organisms have a mouth or mouth parts and are therefore capable of feeding on these organic materials. Some of the most common detritivores secondary decomposers include:. Earthworms are some of the most common animal decomposers. However, they also possess a number of important enzymes in their digestive system.

Apart from dead plant and animal material, worms also feed on a number of other materials such as dung containing partially digested plant material , fungi, and protozoa. As they break down these materials, the end products are mixed with soil thus contributing to soil fertility.

In worms, decomposition of various organic materials starts with the ingestion of tiny materials organic matter in their surroundings. These materials are then moved to the gizzard through the esophagus where they are processed by contraction and grinding actions of the organ.

The small, processed pieces are mixed with liquid calcium carbonate before being moved to the intestine where they are acted upon by bacterial enzymes enzymes are produced by bacteria ingested along with these materials as well as enzymes of the worm e. Nitrate reductase and alkaline phosphatase to release the nutrients required for growth and development. Undigested and partially digested materials known as the cast are finally excreted into the environment.

Like worms, fly larvae are also considered to be detritivores because they ingest dead organic matter thereby contributing to the decomposition process.

Given that maggots start feeding on whatever organic material the eggs were laid on, they accelerate the decomposition process. Unlike worms, maggots lack a properly developed digestive system. For this reason, they secrete a variety of enzymes e. In doing so, they significantly reduce these materials in the environment. Some arthropods like crabs and insects like ants are considered decomposers because they feed on various dead organic matter thus further breaking them down.

One of the biggest advantages of these organisms is that they feed on a wide variety of organic matter including plants and various animal parts including other insects.

Rather, they may be classified as scavengers. Bacteriology as a field of study. Bacterial Transformation , Conjugation. Bacteria - Size, Shape and Arrangement - Eubacteria. Return from Are Bacteria Decomposers?

Haifa form the reproductive structure, mushroom or the mold contain spores by which fungi reproduce. We usually found fungi under the ground on pieces of wood r undecayed food. Fungi are formed by one or many eukaryotic cells. Fungi eukaryotic cells are enveloped by a cellular wall or contain no chlorophyll. They not form tissues as in case of animal, they form Haifa. Some fungi are edible and tasty like mushroom or truffles, Some fungi can be toxic.

Some fungi are harmful for health to may cause lungs disease. And some fungi are produced antibiotics substances used as medicine. Penicillin is the famous antibiotic which use mostly.

Fungi can be found in air, water or in plants. They are mainly transmitted through contact or poor hygiene. Generally, fungi are heterotrophs in nature. It means they depends on other living organism for their food. For example, some type of molds decomposes fruits and vegetables to be able to feed themselves and growing. The substances they decompose are also sources of soil nutrients.

That plants and other living being feed on. Bacteria are micro-organisms. Bacteria are living being. They are unicellular. They are prokaryotic cell meaning they have a nucleus. When plants drop leaves, twigs, and other material to the ground, it piles up. An illustration gallery and information on the African savannah ecosystem.

Image Millipede Detritivore While decomposers break down dead, organic materials, detritivores—like millipedes, earthworms, and termites—eat dead organisms and wastes.

Polyrhachis Armata Ant. Flowering plants angiosperms evolved to attract insects some Most mammals cannot survive by eating moss exclusively, although many occasionally nibble at it.

Pikas use a tactic called copraphagia to extract maximal nutrition from moss: they eat their own feces and re-digest it. Caribou and reindeer feed primarily on a plant called caribou moss during mid-winter.

Algae are single-celled, plant-like organisms. They are producers because they make their own food through photosynthesis. In a food web nutrients are recycled in the end by decomposers. Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients. Decomposers work at every level, setting free nutrients that form an essential part of the total food web. Algae parasitic on land plants are known only among the Chlorophyta.

Some green algae, such as Cephaleuros and Chlorochytrium, may be purely epiphytic or endophytic respectively, or their associations with plants may grade into true parasitism. Fungi are heterotrophic in nutrition. They are chlorophyll deficient plant they cannot manufacture carbohydrates using carbon dioxide, water and sunlight. Fungi are with simple structural organization thus they always depends on dead or living organic matter for their energy requirements.

Seaweeds are algae. Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy.

Kelp, like most autotrophs, creates energy through a process called photosynthesis. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Humans and animals are called heterotrophs because they cannot synthesise their own food but depend on other organisms for their food.

Animals depend on other organisms for getting their food. They cannot make their own food, so they are heterotrophs. S: Autotrophs are also called producers because they produce the organic molecules that serve as food for the organisms in their ecosystem. All living things on Earth need energy in order to survive, and in most cases, this energy comes from the sun.

Heterotrophic organisms must consume other organisms to receive energy. Begin typing your search term above and press enter to search. Press ESC to cancel.
