Parental care is any parental behavior (feeding, protecting, teaching) that boosts offspring survival; in AP Environmental Science it signals a K-selected reproductive strategy linked to Type I or Type II survivorship curves.
Parental care is anything a parent does to keep its offspring alive: feeding them, defending them, teaching them, sticking around. On the AP exam this isn't really about cute animal behavior. It's a clue about a species' whole reproductive strategy.
Here's the logic. Species that pour energy into parental care usually have few offspring and invest a lot in each one. That's a K-selected strategy. Because the parents protect their young, most offspring survive infancy, which produces a Type I survivorship curve (low death rate early in life, deaths bunched up at old age). Species with little or no parental care tend to have tons of offspring and let chance sort them out, which is r-selected and produces a Type III curve (huge early die-off). So when you see "parental care," think K-selected, Type I, low reproductive rate.
Parental care lives in Unit 3: Populations, specifically Topic 3.3 Survivorship Curves. It supports learning objective [AP Enviro 3.3.A] (explain survivorship curves) and the essential knowledge that survivorship curves differ for K-selected and r-selected species (EK ERT-3.C.1 and EK ERT-3.C.2). The term is your shortcut for placing a species on the K-to-r spectrum. If a question hands you a slow-reproducing animal that guards its young, you should immediately reach for "K-selected, Type I." This same reasoning shows up again in conservation questions, because the species most vulnerable to extinction (large mammals with few young and heavy parental investment) recover slowly precisely because of that low reproductive rate.

Survivorship Curves (Unit 3)
Parental care is the behavior that produces a Type I curve. Protect your few offspring well and almost all of them survive to old age, which flattens the early part of the curve and bunches deaths at the far right.
Precocial and Altricial Offspring (Unit 3)
Altricial offspring are born helpless and demand heavy parental care (think baby birds), while precocial offspring can fend for themselves almost immediately. More altricial usually means more parental investment and a more K-selected pattern.
Reproductive Rate (Unit 3)
Parental care and reproductive rate trade off against each other. You can have many offspring with little care (r-selected) or few offspring with lots of care (K-selected), but you can't max out both at once.
Brood Parasitism (Unit 3)
Brood parasitism is the cheat code that outsources parental care. A species like the cuckoo lays eggs in another bird's nest so the host does all the feeding and protecting for free.
Parental care almost always appears as a trait in a list that you use to classify a species. MCQ stems do this constantly, asking which combination of traits is consistent (or LEAST consistent) with a given survivorship curve. A species with strong parental care fits a Type I or Type II curve, not a Type III. On FRQs, the 2017 SAQ about declining African elephants and snow leopards is the classic frame. These large animals are K-selected with high parental investment and low reproductive rates, so once their numbers crash they bounce back slowly, which is exactly why they're vulnerable to extinction. Your job is to connect the dots: parental care implies K-selection implies few offspring implies slow recovery.
Parental care is a behavior (what parents do for offspring), while reproductive rate is a number (how many offspring get produced). They're inversely linked, not the same thing. High parental care typically goes with a LOW reproductive rate because each offspring gets a big slice of parental energy.
Parental care is any parental behavior, like feeding, protecting, or teaching, that increases offspring survival.
Heavy parental care is a hallmark of K-selected species and produces a Type I survivorship curve.
Species with little parental care are usually r-selected and show Type III curves with massive early die-off.
Parental care trades off against reproductive rate, so more care per offspring means fewer offspring overall.
Large mammals like elephants invest heavily in few young, which is why they recover slowly and face extinction risk.
It's any behavior parents use to boost their offspring's survival, such as feeding, defending, or teaching them. On the exam it's a signal that a species is K-selected and follows a Type I survivorship curve.
No, it's the opposite. High parental care goes with FEW offspring because the parents invest heavily in each one, which is the K-selected strategy. Species with many offspring (r-selected) provide little or no care.
Parental care is a behavior (what parents do), while reproductive rate is a count (how many offspring are made). They're inversely related, so high parental care usually pairs with a low reproductive rate.
Because heavy parental care comes with few offspring and a low reproductive rate, populations recover slowly after a decline. This is why large animals like African elephants and snow leopards, featured in a 2017 SAQ, are at high extinction risk.
Type I, and sometimes Type II. Strong parental care keeps most offspring alive through their early years, so deaths cluster at old age rather than at birth.
