Problem: How do protists get food?How can protists be grouped in terms of their ecology. Give 3 examples of important protists.

Protist attain their food in the similar manner with the eukaryotes. It can get their food thru the following process: 

• Plant-like protists get their food through photosynthesis. It is often observed in algae
• Some protist like fungi, get their nutrients through decomposition of decaying materials. 
• Animal-like protists called filter feeders use their tail (flagellum) to create a current that bring the food towards its direction. It uses endocytosis to engulf their food.
