<span>Amoeba obtain nutrition by holozoic mode. It engulfs food, which remains iside the vacoule where digestion takes place. Vacoule move inside and fuse with lysosome, which releases proteases and amylase for digection of the engulfed food. The digested food is absorbed by the cell. Undigesed food remains in the vacoule, which fuses with cytoplasmic membrane and ruptures to throw the excreta.</span>
They are herbivores which means they eat grass, mostly trees and bushes
Cohesion known as water attraction to other water molecules is one of the major properties of water. liquid water has surface tension. this allows for insects such as water striders to walk on water. question number 3 the answer is because ice is less dense then liquid water because the water molecules for a new large structure as they cool down. of course Lakes freeze a course from top down even though the coldest areas are at the bottom. cold water begins to rises when it begins to freeze it accumulates at the top with a sheet of ice. the ice provides some insulation for the water below so that there is typically a significant portion of water under the ice sheet unless it's extraordinary really cold for a very very very very long time. if a lake froze from the bottom up they would more than likely freeze completely
