Which protists are consumers?

Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria.

What are 3 protists?

The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or fungi. Organisms in the Protista kingdom include amoebae, red algae, dinoflagellates, diatoms, euglena, and slime molds….More plant-like protists include:

  • Dinoflagellates.
  • Diatoms.
  • Euglenoids.
  • Red algae.
  • Green algae.
  • Brown algae.

Which protists are 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.

What are the four protists?

The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.

What is a protist disease?

Protists are responsible for a variety of human diseases including malaria, sleeping sickness, amoebic dysentery and trichomoniasis. Malaria in humans is a devastating disease.

What are protist groups?

Plant-like protists are called algae (singular, alga). They are a large and diverse group. Some algae, diatoms, are single-celled….Classification of Algae.

Is protista a decomposer?

Yes, protists are decomposers.

What is a protist cell?

Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.

What kind of protists are like a plant?

Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Like plants, they contain chlorophyll and make food by photosynthesis. Types of algae include red and green algae, euglenids, and dinoflagellates. Fungus-like protists are molds. They are absorptive feeders, found on decaying organic matter.

How are bacteria, protists, and fungi multicellular?

However, some can be multicellular, such as kelp (protist) and mushrooms (fungi). While protists can be consumers (animal-like), producers, (plant-like) and decomposers (fungi-like), all fungi are decomposers. Again, I pass around pictures to support visual learners: Pictures of Bacteria, Protists, & Fungi .

Which is the largest group of autotrophic protists?

The largest group of autotrophic protists is collectively called algae. You have probably heard of algae before, even if you didn’t know that they were classified as autotrophic protists!

How does the silica shell protect a protist?

This silica shell provides a certain level of protection against predators. A collection of diatoms, as seen under the microscope. Some protists have the ability to move around in the water column through the use of cilia or flagella, while others rely on water currents to move them around.
