• Ruby-crowned kinglets have a weight of only 0.24 oz (that's about the weight of your eyeball!). Some populations migrate south but many will see

out the winter in their summer habitat. To survive the long, cold nights,

these tiny birds will huddle' up together. Explain why this behavior may

have evolved using ideas learned during this unit relating to cells' surface

area and volume.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
