How do plantlike protist affect other living things?

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.


Are microscopic organisms harmful?

What are 10 examples of fungi like protists?

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.
