Final answer:
Poppies tend to grow on battlefields due to their ability to lie underground for years and bloom when the ground is disturbed. The association between red poppies and World War I led to the adoption of the poppy as a symbol of remembrance for fallen soldiers.
Step-by-step explanation:
Poppies tend to grow on battlefields because their seeds can lie underground for years and can bloom when the ground is disturbed, such as during battles and war. The red poppies that grow on battlefields became associated with World War I due to their prevalence in the fields of the Ypres salient in Belgium after the Second Battle of Ypres in 1915.
This association with war and the symbolism of poppies as a remembrance and memorial flower led to the adoption of the poppy as a symbol of remembrance for fallen soldiers in various countries, including the United States, Canada, and France.
It's important to note that poppies also have other uses, such as being used in the production of opium and its derivatives.
