Are protists beneficial or harmful to humans explain why?

Are protists beneficial or harmful to humans explain why?

The kingdom Protista is a diverse group of organisms. Some protists are harmful, but many more are beneficial. These organisms form the foundation for food chains, produce the oxygen we breathe, and play an important role in nutrient recycling. Many protists are economically useful as well.

What protist is beneficial?

Brown and Red Algae Phaeophyta, or brown algae, are also beneficial types of protist. These include algae such as kelp. These algae are food sources for fish as well as humans. They have large amounts of iodine, which is a necessary nutrient for life.

Can protists be helpful for living things?

Protists also play an important role in the environment. According to CK-12, plant-like protists produce almost half of the oxygen on Earth through photosynthesis. Protists act as decomposers and help in recycling nutrients through ecosystems, according to the educational website Biology Online (opens in new tab).

What are the economic importance of protists?

Economic Importance of Protists Protists serve as the foundation of the food chain. Protists are symbionts – having a close relationship between two species in which, one is benefited. Some protists also produce oxygen and may be used to produce biofuel. Protists are the primary sources of food for many animals.

How are protists important in the world of evolution?

Some important characteristics arose in protists during their evolution as explained by the endosymbiotic theory and it's evidence. There was a nucleus that was divided by mitosis. There was an endomembrane system and a cytoskeleton system that they developed. They could develop flagella or cilia for locomotion.

What roles do protists play in the ecosystem?

Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers. In addition, many protists are parasites of plants and animals that can cause deadly human diseases or destroy valuable crops.

What is the evolutionary importance of protists?

What is the evolutionary importance of protists? Scientific evidence points to that eukaryotic organelles as mitochondria and chloroplasts originated as prokaryotes that first lived within larger prokaryotic cells. Therefore, the protists evolved from the prokaryotic cells.

Which role of protists has the most positive effect?

Which role of protists has the most positive effect on maintaining the plant population in an ecosystem? Protists decompose dead materials, returning nutrients to the soil.

What roles do protists play in the ecosystems?

Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers. In addition, many protists are parasites of plants and animals that can cause deadly human diseases or destroy valuable crops.
