Which two examples undergo dormancy?
Mouse
Rose Bush
Human
Black Bear
Oak Tree
Squirrel
The two examples that undergo dormancy are the Oak Tree and the Squirrel. Oak trees undergo dormancy during the winter season and squirrel undergoes dormancy during the summer season. During this period, the metabolism of these organisms slows down, allowing them to conserve energy and survive harsh environmental conditions.
To identify which two examples undergo dormancy, we need to understand what dormancy means. Dormancy is a period of inactivity or slowed metabolic activity in an organism, typically triggered by environmental conditions such as extreme temperatures, changes in light, or limited food availability. This adaptation helps organisms survive unfavorable conditions.
Let's go through each example you provided:
1. Mouse: Mice do not undergo true dormancy. They do experience torpor, a short-term period of decreased activity and lowered body temperature, but it is not considered full dormancy.
2. Rose Bush: Rose bushes, like many deciduous plants, undergo dormancy during the winter months. They lose their leaves and become dormant to conserve energy until the weather becomes more favorable for growth.
3. Human: Humans do not undergo dormancy. We maintain a constant body temperature and do not have periods of inactivity due to environmental conditions.
4. Black Bear: Black bears undergo true winter dormancy called hibernation. During this period, their metabolic rate and body temperature decrease, allowing them to conserve energy and survive through the winter when food is scarce.
5. Oak Tree: Oak trees, like rose bushes, are deciduous trees that undergo dormancy during the winter. They lose their leaves and become dormant until the conditions are suitable for growth.
6. Squirrel: Some species of squirrels, such as the ground squirrel, undergo a form of dormancy called hibernation. They store food and reduce their activity levels during the winter months to conserve energy.
Based on the information provided, the two examples that undergo dormancy are the rose bush and the black bear.
The two examples that undergo dormancy are:
1. Rose Bush: Rose bushes undergo a period of dormancy during winter. They shed their leaves and slow down their metabolic processes to survive the cold temperatures. During this dormant period, they conserve energy and protect themselves from freezing temperatures.
2. Oak Tree: Oak trees also undergo dormancy during the winter months. Similar to rose bushes, oak trees shed their leaves and enter a period of reduced activity. They conserve energy and wait for warmer conditions before resuming growth and metabolic activities.
