How do phytoplankton amoebas and Giardia lamblia eat?

Answer 1

Phytoplankton eat by photosynthesis, Amoebas use their pseudopodia or "false feet" to sense the food, move towards it, and surround it with its "false feet". This action forms a food vacuole. Enzymes move into the vacuole to digest the food, and the digested food passes into the amoeba. Giardia live in the gut of termites, it digests the cell walls of the wood that the termites eat.
