Is yeast an r-selected or K-selected species? Based on the type of selection for yeast, list four factors they exhibit
Homework Answers
Species which is population density dependent is called k-selected species and which is population density independent is called R-selected species.
Yeast is a r-selected species and exhibits following four factors :
1. They are short lived.
2. They reproduce at an early age.
3. They have fast maturation.
4. They care little for their offsprings.
