How does an early onset of spring through climate change affect plants?
a.
their growing and flowering season starts earlier and is longer
b.
their growing and flowering season starts later and is longer
c.
their growing and flowering season starts earlier and is shorter
d.
their growing and flowering season starts later and is shorter

The answer is letter A. 

Plants that are affected by climate change tend to have a growing and flowering season that starts very early and lasts longer than normal. This certainly puts an imbalance in the ecosystem which causes many environments to have a different stake of demand and supply for food for other primary and secondary consumers. The early onset of spring affects the plant's budding time which would then escalate to early development of fruits and later on will progress to a lack of supply when the need for that food arises for other organisms.
