My answer will be because these characteristics intervene in the capture and assimilation of the food, having 4 general food behaviors: (1) detritivores, consume a lot of material from the bottom of the water source, (2) herbivores, who consume mostly plant components (filamentous algae and higher plants); (3) periphyton consumers, who are characterized by feeding on microalgae and microinvertebrates and (4) omnivores, in which they indistinctly feed on plant material as an animal of different origin.
Photosynthesis means like sun and plants it would be that numerical order in which this would compare to the broad and conjust modives
since the roots hairs grow in soil particles, they get water from the soil, thereby the cell wall and cell membrane absorbs the water through osmosis before transferring it to other parts of the roots
