K-selected species produce fewer offspring and invest significant parental care to ensure survival. This follows from NCERT principle where relation explains outcome clearly for students.

K-selected species produce fewer offspring and invest significant parental care to ensure survival.

K-selected species invest in high parental care, ensuring the survival of fewer but more competitive offspring.

K-selected species produce fewer offspring, invest in parental care, and have longer lifespans.

“Have large body size” for k-selected species typically. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Survivorship curves summarize age-specific mortality: Type I concentrates loss late in life, Type II approximates a constant hazard, and Type III concentrates loss early. They are empirical patterns, not rigid taxonomic rules. The remaining alternatives—“Exhibit semelparity”, “Reproduce early”, “Thrive in disturbed habitats”—refer to different states, processes, or scales and therefore do not e

The keyed exception is “Show early semelparity.” In the context of which of the following is false regarding k-selected species, that statement differs from the governing ecological pattern and must be evaluated against the mechanism rather than accepted from wording alone. Mechanistic support comes from showing how resource limitation, enemies, mate availability, or physiological stress changes demographic performance. A descriptive association alone does not establish regulation or causation. The remaining alternatives—“Low reproductive rate”, “High parental investment”, “Thrive in stable en
