Question

adapted to unstable environmental conditions, leading to wild fluctuations in their population size above and below carrying capacity. r - selected species have a generalized niche and rely on sheer numbers for survival. an example of an r - selected species are cockroaches.
what is a characteristic of r - selected species?

• very large body size
• high parental care
• little to no parental care
• stable population size

Explanation:

r-selected species prioritize high reproductive output over individual offspring survival. They typically have little to no parental care, as seen in cockroaches (the example given), which produce many offspring that fend for themselves. The other options (very large body size, high parental care, stable population size) are characteristics of K-selected species, not r-selected ones.

Answer:

little to no parental care
