What energy transfer is used to determine the rate of primary productivity? A. Solar energy being converted into chemical energy

B. Solar energy being converted to mechanical energy

C. Thermal energy is converted to chemical energy

D. Thermal energy is converted to mechanical energy

A. Solar energy being converted into chemical energy

Explanation:

Solar energy from the Sun is used by the primary producers which are plants through photosynthesis in the production of chemical energy. This validates the conversion of solar to chemical energy as a way of measuring primary productivity in the ecosystem.

The chemical energy which is in the form of molecules such as glucose(C6H12O6) are what the consumers feed on to enable sustainability.

ek = (m.v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) v2/2

ek = (200 + 250) 2,32/2 = 450*5,29/2 = 1190,25 j
