Volvox is a type of protist that has a chloroplast, but does not have an oral groove. What does this tell you about Volvox and how it obtains nutrients needed for energy? Please help me

answerlinnaeus;

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
