Free living
Yes
Some amoebas are parasitic, meaning they live inside another organism and obtain nutrients at the host's expense. However, not all amoebas are parasitic, as there are many free-living species that feed on bacteria and algae in various environments.
Amoebas can have several negative effects, particularly when they are pathogenic. For instance, the species Entamoeba histolytica can cause amoebic dysentery, leading to severe diarrhea, abdominal pain, and dehydration. Additionally, some free-living amoebas, like Naegleria fowleri, can cause fatal brain infections in humans. Their presence in contaminated water sources can pose significant health risks, particularly in immunocompromised individuals.

amoebas
In Griffith's experiment, non-pathogenic bacteria were transformed into pathogenic bacteria by being exposed to heat-killed pathogenic bacteria, a process now known as transformation. This led to the discovery of genetic material transfer between bacteria.
Yes, some species of amoebas, such as the Naegleria fowleri, can be pathogenic to humans and cause infections such as amoebic meningoencephalitis, a rare but usually fatal infection that affects the brain. These amoebas are usually found in warm freshwater bodies like rivers and lakes.
Amoebas belong to the phylum Amoebozoa. This group is characterized by their ability to change shape through the use of pseudopodia, which are extensions of their cytoplasm. Amoebozoa includes various species, some of which are free-living while others are parasitic. They are primarily found in aquatic environments and soil.
Non-pathogenic amoebas are commonly found in various aquatic environments such as freshwater bodies like lakes, ponds, and rivers, as well as in soil. They play important roles in nutrient cycling and decomposition processes in these habitats. Several species also form symbiotic relationships with other organisms.
