wildlife is plentiful in the piney woods. There are over 100 species of birds and many small mammals, like cottontail rabbits and squirrels. What else must be included in the piney woods habitat to keep population in balance?

Answers

Answer: A predator species

Wildlife is plentiful in the piney woods and there are over 100 species of birds and many small mammals, like cottontails, rabbits and squirrels. All these species are relying for a same resource in order to maintain the population of these species a limiting factor is required which can cause elimination, extinction and migration of these species and limit their surplus population, hence maintain the balance of nature. A predator population can be a potent limiting factor here, as it can feed upon these species. Therefore, a predator species must be included in the piney woods habitat to keep population in balance.

It is predators like snakes because predators keep the population control, without predators the population can go soo high that thers not enough food for all of the population. Then the population starts dyeing off.

Who won the battle of somme? explain

Answers

Neither side really won. The British and French, who started the battle, won some ground, but it wasn't much and their casualty rate was very high. The British & French lost about 620,000 men; the Germans lost about 500,000. 

The goal of the battle was to make a breakthrough against the German lines and to take some of the pressure off of French troops who were fighting the Germans at Verdun. I believe the casualties were higher at the Battle of the Somme than at Verdun.
