Are protists decomposers consumers or producers?

Asked by: Kateri Willauer

Complete answer: Many protist species are decomposers, meaning they feed on dead organisms to meet their nutritional needs. Protists are single-celled eukaryotes that live in pond water, but they also live in a variety of other marine and terrestrial habitats and fill a variety of niches.

Can a protist be a consumer?

Slime-moulds are also known as consumer-decomposer protists. They are also known as protist fungi. The vegetative phase of slime moulds lack cell walls and the spores possess true walls. They are found creeping on decaying plant parts and on forest floors and feed on them.

Are some protists consumers and producers?

Primary Producers/Food Sources
In some cases, as with zooplankton, protists are consumed directly. Alternatively, photosynthetic protists serve as producers of nutrition for other organisms. Paramecium bursaria and several other species of ciliates are mixotrophic due to a symbiotic relationship with green algae.

Is decomposers a protist or fungi?

Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.

What are some protists that are consumers?

Examples include Amoeba and Paramecium. Fungus-like protists are heterotrophs or consumers which need to be attached to their food source in order to absorb nutrients. They help to decompose dead and decaying matter. Like fungi they also have a cell wall and reproduce using spores which come from fruiting bodies.

Are protists decomposers?

Yes, protists are decomposers.

How do protists consume food?

Protists get food in one of three ways. They may ingest, absorb, or make their own organic molecules. Ingestive protists ingest, or engulf, bacteria and other small particles. They extend their cell wall an d cell membr ane around the food item, forming a food vacuole.

Are all decomposers consumers?

Decomposers get energy through respiration, so they are heterotrophs. However, their energy is obtained at the cellular level, so they are called decomposers not consumers.

Are protists autotrophs or heterotrophs?

Classification of Protists
Protozoa (animal-like protists) are heterotrophs that ingest or absorb their food and helps. 2. Algae (plant-like protists) are autotrophs they get nutrition from photosythesis.

Is protists biotic or abiotic?

Biotic factors

Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.

Are protists the base of the food chain?

Some protist species are essential components of the food chain and are generators of biomass. Protists are essential sources of nutrition for many other organisms. In some cases, as in plankton, protists are consumed directly. Alternatively, photosynthetic protists serve as producers of nutrition for other organisms.

Which is a food source for protists?

Protists Nutrition
That means that protists can obtain food like plants, fungi, or animals do. There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis. Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter.

What type of protist makes its own food?

Plant-like protists are autotrophs. This means that they create their own food without having to eat or engulf other organisms/organic materials in the environment. Plant-like protists have chloroplasts in their cells in order to perform photosynthesis in order to convert sunlight into food (aka glucose).

Are protists producers?

As primary producers, protists feed a large proportion of the world’s aquatic species. (On land, terrestrial plants serve as primary producers.) In fact, approximately one-quarter of the world’s photosynthesis is conducted by protists, particularly dinoflagellates, diatoms, and multicellular algae.

Do protists make their own food?

Some make their own food, but most take in or absorb food. Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis.
