Select the examples that describe delayed density dependence. More than one answer is correct.
An abundant fall allows a large population of black bears to store enough fat reserves to survive hibernation in the winter, but a harsh winter causes food to be scarce in the spring when the bears wake up, causing many bears to die before reproducing.
In dry areas, mesquite seedlings do not grow near mature mesquite trees because roots of established trees out-compete the seedlings for limited water. As the density of mature trees increases, the population growth rate simultaneously slows.
A healthy herd of deer breeds in the fall. A harsh winter results in the loss of key food sources. Many fawns are born malnourished and do not recover.
A fire sweeps through a young pine forest, killing most of the new pine seedlings and injuring some of the mature trees.
