What is not true about energy transformation in living things?

a. energy from respiration is recycled by plants to carry out photosynthesis

b. light energy is converted to chemical energy by plants during photosynthesis

c. chemical energy is transformed to heat energy as organisms carry out respiration

d. energy is stored by plants in bonds of organic compounds used as food

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

the answer is c. it will give up it's valence electron to the other atom.

i think this picture will you.
