Why do ants gather in large groups?

A large group of ants in one location is an indication that an aggregation pheromone has been released, although the reason for its release may not be evident to humans.

Do ant colonies go to war?

Large ant colonies with tens or hundreds of thousands of members engage in all-out war with other colonies as they compete for resources. When considering the often-striking similarities between humans and social insects, one fascinating parallel is the existence of warfare in both.

What do ants do when the Queen dies?

The answer is obvious: the colony dies. Ants won’t flee to another territory if their queen passes away. Instead, they continue bringing resources back to the settlement until they die of old age or external causes. There won’t be a successor to the queen if one dies unless it was a rare situation of multiple queens.

Where do birds go when it rains?

Why did people settle in the New England colonies?

However, the New England colonies did have access to oceans full of fish. They also had access to large forests and harbors in which to trade.

What was the climate like in the New England colonies?

The New England colonies had a colder, harsher climate. While colonists there did farm, their climate was not conducive to the growing of major cash crops like tobacco.

Why do trees get uprooted in the wind?

One main reason, all three experts agree, is the phenomenon known as “windthrow” which uproots a tree. “The tree trunk acts as a lever and so the force applied to the roots and trunk increases with height,” says Foster.
