Plant-like protists can release toxins into their environment, which can harm other organisms. They can also disrupt ecosystems by outcompeting native species for resources, leading to imbalances in the ecosystem. Additionally, some plant-like protists can cause harmful algal blooms, which deplete oxygen levels in water and lead to the death of marine organisms.
Protists can be both helpful and harmful. Some protists are beneficial as they play key roles in ecosystems, such as being primary producers in marine environments. However, some protists can also be harmful pathogens that cause diseases in humans, animals, and plants.
Some protists have them. Algae are some protists .
No, there are living single cell organisms
Algae and bacteria. They may be small, but they are living and not plants or animals.
Because it shields living organisms from some harmful radiation from the Sun
No, most protists are unicellular organisms. Some protists can form colonies or be multicellular, but the majority are single-celled.
Some protists, such as algae, produce oxygen through photosynthesis. These organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for supporting other organisms that rely on oxygen for respiration.
The smallest protists are typically single-celled organisms known as picoplankton. These tiny protists can be as small as 0.2 micrometers in size, making them some of the smallest eukaryotic organisms on Earth.
Plant-like protists, such as algae, can affect other living things by producing oxygen through photosynthesis, which is essential for the survival of many organisms. Additionally, some plant-like protists can serve as food sources for other organisms in aquatic ecosystems, forming the base of the food chain. However, excessive growth of plant-like protists, such as harmful algal blooms, can have negative effects on other organisms by depleting oxygen and producing toxins.
Some of them are, however, there are many microscopic organisms that are not harmful, some of which you could not survive without.
These protists share many characteristivd with Fungi. However, because of their differences from Fungi they are classified as protists. Funguslike protists play a valuable role in the ecosystem. They break down dead plant and animal matter, making the nutrients from these dead orgainsms available for living organisms. While some slime molds and water molds are benefical, many others can be very harmful. Many fuguslike protsts attack and consume living plants.
