Answer:
1,000 kcal
Explanation:
As a general rule, every trophic level only gains 10% of the energy from the trophic level.
So, the grass has 100,000 kcal of energy. Assuming the bird eats grass, it only gets 10,000 kcal of energy. Assuming the fox eats the bird, it only gains 1,000 kcal of energy.

Answer:
The correct answer is NADPH.
Photo-system I absorbs maximum photons at the wavelength of 700 nm.
It uses this energy to transfer the electron (received from photo-system II) to NADP⁺ to reduce it to NADPH.
Once, the reaction centre of PS I or P₇₀₀ gets excited, it transfer the high energy electron to the ferrodoxin (Fd) via cluster of iron and sulphur protein (4Fe-4S).
Reduced ferrodoxin then transfer the electron to NADP⁺ to reduce it to NADPH with the help of flavoprotein (ferrodoxin-NADP⁺ reductase).
NADPH is then used in Calvin cycle or light-independent phase of the photosynthesis in order to fix carbon to produce sugar or food.
