Which of these traits is NOT characteristic of r-selected tree species?​

Correct option is A

r-selected species are characterized by traits that allow them to rapidly exploit new habitats and thrive in unpredictable or ephemeral environments. These species are typically small, fast-growing, and produce many offspring with little parental investment.

Here’s why Option 1 is not characteristic of r-selected species:

• r-selected species generally experience density-independent mortality and reproduction. This means that their population dynamics (such as reproduction and survival rates) are not significantly impacted by population density. In contrast, K-selected species are density-dependent, meaning that their growth rates and reproduction are regulated by the available resources and population density.

Information Booster:

1. r-selected species typically exhibit high reproductive rates, producing many offspring in a short period.
2. These species often have a short lifespan and are adapted to environments where resources are abundant for brief periods.
3. Examples of r-selected species include many types of weeds, insects, and small mammals.
4. They are often found in disturbed or changing environments where rapid colonization and reproduction are essential for survival.
5. r-selection is contrasted with K-selection, where organisms are adapted to stable environments with longer lifespans, fewer offspring, and greater parental investment.
