4 Questions
Match the following terms with their descriptions:
Protozoa = Microscopic, single-celled organisms that can be autotrophic or heterotrophic Phytoplankton = Direct food sources for many zooplankton and some fish Biofilms = Covered by sediments formed by protozoa and other microorganisms Cyanobacteria = Some produce toxins that are lethal
Match the following organisms with their feeding habits:
Heterotrophic protozoans (e.g., amoeba) = Consume other organisms like algae or bacteria Phytoplankton = Direct food source for many zooplankton and some fish Cyanobacteria = Some can cause taste and odor problems in the water Zooplankton = Feed on phytoplankton
Match the following statements with the correct organism:
Protozoa form sediments on riverbeds = Protozoa along with other microorganisms Some protozoa are parasites causing giardiasis = Protozoa like Cryptosporidium Phytoplankton are the basis of deep-water food web = Direct food sources for many zooplankton and some fish Cyanobacteria produce toxins lethal to organisms = Some cyanobacteria species
Match the following terms with their impact:
Phytoplankton = Can cause taste and odor problems in the water Cyanobacteria = Produce toxins that can be lethal Protozoa in biofilms = Cover hard surfaces on riverbeds Zooplankton = Feed on phytoplankton as their direct food source
Explore the world of protozoa, microscopic single-celled organisms that can form colonies. Learn about the autotrophic and heterotrophic species, their feeding habits, and their role in the environment. Discover how protozoa contribute to the formation of sediments and biofilms.
