The black kite, whistling kite, and brown falcon are known for using this phenomenon to catch prey. This phenomenon triggers the flowering of Telopea speciosissima, the waratah. Though not (15[1])involving heavy machinery, this phenomenon causes a large decrease in soil porosity; it also increases the concentrations of the nutrients potassium, magnesium, and calcium and thus increases soil pH. Adapting to this phenomenon is the primary function of (*) epicormic buds and lignotubers. (10[1])This phenomenon causes certain trees (-5[1])such as the lodgepole pine (10[1])to release seeds, making them (10[2])serotinous. (10[4])This phenomenon is the most typical natural cause of (10[1])secondary succession. (10[1])Eucalyptus trees (-5[1])are resistant to (10[1])this phenomenon (10[1])while containing oils that promote it. (10[1])For 10 points, name this phenomenon that often starts when dry brush is hit by lightning. ■END■ (10[1])
