3. List one advantage and disadvantage of a monocot root system.

Mono or root systems have fibrous roots These fibrous roots occupy the upper level of the soil in comparison to dicot root structures that dig deeper and create thicker systems.
A disadvantage is that this type of root is not favourable to the water scarce area or drought. So such plants live in the areas where water is easily available.

This is what i found on google “phytoplankton, tiny organisms that live in the ocean, are autotrophs. some types of bacteria are autotrophs. most autotrophs use a process called photosynthesis to make their food.” i hope this you for what your looking for
