Reproduction in essential for the continuation of a species. What will be the effects on Earth if plants fail to reproduce?
Recall that plants are autotrophs, implying that they can synthesize their own food utilizing simple compounds like carbon dioxide and water thereby converting solar energy of the sun to chemical energy. The entire animal kingdom is dependent on plants for their nourishment and energy source. Without plants reproducing, consumption of plants can lead to their extinction which will lead to food shortage and death of animals.
Plants also consume carbon dioxide from the atmosphere and release oxygen thereby maintaining a gaseous balance. Without plants, carbon dioxide will reach peak levels causing an increase in temperature.
