Answer:
Autotrophs are those organism that use of the sunlight to transform the light energy into chemical energy to synthesize their food.
Hence, statement 1 belongs to autotrophs.
All the organism use chemical energy present in the organic molecules to obtain energy in the form of ATP( adenosine triphosphate) molecules.
Hence, statement 2 belongs to both autotrophs and heterotrophs.
Only heterotrophs consumes organic matter from autotrophs to get energy, while autotrophs can make their own food to obtain energy.
Hence, statement 3 belongs to heterotrophs.
Chlorophyll is the green pigment found in the autotrophs(such as green plants and photosynthetic bacteria) that helps in absorbing sunlight to make food.
Hence, statement 4 belongs to autotrophs.
Calvin Cycle involves a series of reaction which includes multiple reaction in it. This is a part of photosynthesis, performed by autotrophs.
Hence, statement 5 belongs to autotrophs.
Krebs's cycle is a part of cellular respiration which is performed by all the living organism to get energy.
Hence, statement 6 belongs to both autotrophs and heterotrophs.
