I think the right answer is that it's "false"
Answer:
In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
This is the chemical equation for photosynthesis
6CO2+6H2O--->C6H12O6+6O2
the inputs are the ones on the left:
carbon dioxide used in the calvin cycle and water used in the light-dependent reactions
the outputs are on the right
glucose resulted from the calvin cycle and oxygen resulted from the light dependent reactions
