Question

vocabulary term: biological fitness
definition:

word breakdown/hint:
which frogs have demonstrated more fitness... dark or light?

describe a scenario/example of biological fitness.
there are only two northern white rhinos left in kenya and they are both female and in great health. would those rhinos be considered biologically fit?

Explanation:

Part 1: Vocabulary Term - Biological Fitness

• Definition: Biological fitness (or Darwinian fitness) is the ability of an organism to survive and reproduce in its environment, passing on its genes to the next generation. It is measured by the number of viable offspring an organism produces relative to others in the population.
• Description/Example of Biological Fitness: For example, in a population of birds, a bird with traits (like better camouflage, stronger beak for food) that allow it to survive longer and have more offspring (who also survive to reproduce) has higher biological fitness. If a frog species lives in a dark, forested area, dark - colored frogs may have higher fitness because they are better camouflaged from predators, so they are more likely to survive and reproduce compared to light - colored frogs in that environment.
• Word Breakdown/Hint (Frog Question): Fitness in biology relates to survival and reproduction. In a dark environment, dark - colored frogs are less visible to predators. So dark - colored frogs would have more fitness as they are more likely to survive to reproduce.
• Rhino Question: Biological fitness isn't just about health; it's about the ability to reproduce and pass on genes. With only two Northern White Rhinos left (and depending on their ability to reproduce, especially if they can't produce viable offspring), even if they are healthy, their biological fitness is low because they can't effectively pass on their genes to the next generation. So those rhinos would not be considered biologically fit in terms of the population's long - term survival and gene propagation.

Part 1 Answer:

• Definition: The ability of an organism to survive and reproduce in its environment, measured by the number of viable offspring it produces relative to others.
• Description/Example of Biological Fitness: A bird with traits enabling more offspring survival has high fitness; dark frogs in a dark forest (due to better camouflage) have more fitness than light frogs there.
• Frog Fitness: Dark - colored frogs (in a dark environment) have more fitness as they are better camouflaged, increasing survival and reproduction chances.
• Rhino Fitness: No, the two Northern White Rhinos (even if healthy) have low biological fitness because they can't effectively reproduce and pass on genes to sustain the population.
