Importance of Survival

Animals and plants need food to survive.  One animal species is a source of food to another.  For example, eagles eat snakes.  If snakes do not survive, there will be shortage of food for eagles.  The eagles may become extinct.

Animals and plants may become extinct because of some other factors.  This includes illegal hunting, deforestation and natural disasters.

Illegal hunting
