The energy is transferred starting from the Sun which is necessary for the plant's photosynthesis then move towards animals consuming plants as food.

Answer:
Option (4).
Explanation:
Phosphatidylinositol4,5-bisphosphate (PIP2) is the phospholipid present in plasma membrane. This lipid is important for the cell communication and cell signalling process.
The PIP2 can cleave and give two main products are DAG (diacylglycerol) and IP3 ( inositol 1,4,5-trisphosphate). These two molecules are important for the cell signalling.
Thus, the correct answer is option (4).
