I don’t see any labels, but remember that humans are a great example of a k-selected species. High rates of parental care leads to high survivorship of offspring, and thus negates the need to have large amounts of offspring.
R-selected species are quite the opposite. They produce large amounts of offspring at many intervals in an attempt to maximize survivorship, as they don’t have strong parental involvement with their young. Think of insects.
Your answer should be lakes and forests. Acid precipitation will rot out forests because of the acid content and in lakes it raises the PH balance making it more acidic which in turn makes it harder for anything to live in these lakes or drink from them. (Hope this helps ^-^)
Archae can live in extreme settings, like super cold or super hot places
Archae have no peptidoglycan in cell walls, while Eubacteria do
Eukarya are things like fungi, plant, animal cells
Not all Eukarya have cells walls

Pre-frontal Cortex (PFC)
The PFC is often one of the last regions of the cerebral cortex to fully develop. It is the area of the brain most associated with executive function, logic, reason, and some anticipation of consequences.
Research estimates that most females' PFC is nearly fully developed by ages 16-21; however, males lag in this development of their PFC by an average of ages 19-24.
Thus, before legal age (18), minors (males > females) are more apt to partake in risk-taking behaviors.
