Generalist vs

Questions and Answers

Explain ONE characteristic of specialist species that makes them more likely to become extinct than generalist species.

Specialist species have a smaller range of tolerance and a narrower ecological niche, making them more prone to extinction due to specific food requirements and less ability to adapt to new conditions.

Differentiate between r-selected and K-selected species based on their reproductive strategies.

R-selected species prioritize 'quantity' with many offspring and little to no parental care, while K-selected species prioritize 'quality' with few offspring and heavy parental care to protect them.

List TWO traits or characteristics of r-selected species.

R-selected species have a high biotic potential, with a quick reproductive rate and high population growth rate. 2) They have a shorter lifespan and are quick to reach sexual maturity.

List TWO traits or characteristics of K-selected species.

<ol> <li>K-selected species have a low biotic potential, with a slow population growth rate and long time to sexual maturity. 2) They have a long lifespan and are more likely to be disrupted by environmental changes.</li> </ol> Signup and view all the answers

Explain the concept of parental care on the spectrum of K-selected species.

<p>K-selected species exhibit low biotic potential and require heavy parental care to protect their few offspring, making it hard for the population to recover after a disturbance in the environment.</p> Signup and view all the answers
