Step 1: Storage carbohydrate in plants.
Plants store carbohydrates mainly in the form of starch.
Starch is a polysaccharide made up of glucose units and acts as an energy reserve in plants.
Step 2: Storage carbohydrate in animals.
Animals store carbohydrates in the form of glycogen.
Glycogen is also a polysaccharide of glucose and is mainly stored in liver and muscles.
Step 3: Compare the options.
Plants:
Starch
Animals:
Glycogen
Thus, the correct sequence is:
Starch, Glycogen
Step 4: Final conclusion.
Hence, the correct answer is
\[
\boxed{\text{Starch, Glycogen}}
\]
