  3. 3. Douglas fir tree Ecologists refer to the reduction in future reproductive potential resulting from current reproductive efforts as the cost of reproduction.
  4. 4. Reproductive strategies • There are a wide range of reproductive strategies employed by different species.
  5. 5. Other types of reproductive strategies • Polycyclic organisms • Semelparous organisms • Iteroparous organisms
  6. 6. Life without reproduction • The biological study of how the origin of life led from non- reproducing elements to reproducing organisms is called abiogenesis.
  7. 7. Lottery principle • George C. Williams used lottery tickets as an analogy in one explanation for the widespread use of sexual reproduction.
