The continuation of life depends of both what and what

The continuation of life depends on both sexual and asexual reproduction.

Reproduction is a process where an organism gives rise to another organism, often called as "offspring". Its a process of increasing the population of any species on Earth. There are two types of reproduction process-

1. Asexual - where exact copies of parent organism are formed, also only single parent is involved.

2. Sexual - Two parents of opposite sexes are involved, offsprings are not identical to parents. There is scope of variation in sexual reproduction.
