Answer:
The three parts of the cell theory are: cells are the smallest unit of life; all cells come from preexisting cells; and living thing is made up of one or more cell.
The air in Greg's house is like the cytoplasm of a cell because it is the gel-like material that surrounds the other parts of the cell.
Hope this helps! :)
Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
