Lots of things experience dormancy. Many species of plants for example. Look out your window at the deciduous trees (the ones that have lost their leaves for the winter). They are dormant. Many animals also experience dormancy, and it comes in a variety of forms. Hibernation is a sort of dormancy. Dormancy means that an organism stops growing, stops developing and largely ceases activity. Dormancy results when adverse conditions occur and a plant or an animal recognizes that to survive, it must cease normal “life” and put the brakes on growth, development, and activity. Dormancy comes in a couple of ways. Predictive dormancy happens when the length of days shortens, temperatures lower or water is limited. The organism reacts to signs like these and goes dormant prior to adverse conditions. Consequential dormancy happens after the fact. After unpredictable environmental conditions worsen, the plant or animal reacts by going dormant.
