Life Cycle Phases
The life cycle of an organism can be divided into three phases, which are:
1. Juvenile Phase
- This phase starts from the birth or hatching of an individual and lasts until it reaches reproductive maturity.
- During this phase, the individual undergoes significant growth and development, acquires skills needed for survival and learns behaviors necessary for reproduction.
- This phase varies in duration depending on the species and environmental conditions.
2. Reproductive Phase
- This phase starts when an individual reaches sexual maturity and begins to reproduce.
- During this phase, an individual engages in courtship behavior, mates and produces offspring.
- The reproductive phase is essential for the survival and continuation of a species.
3. Senescence Phase
- This phase starts when an individual reaches the end of its reproductive life.
- During this phase, an individual experiences a decline in physical and cognitive abilities, making it more vulnerable to disease, predation, and environmental stressors.
- This phase leads to death, which marks the end of an individual's life cycle.
Therefore, the correct answer is option 'D', which states the three phases in order as juvenile, reproductive, and senescence.

There are 3 phases in a life cycle.
(i) Juvenile phase/ vegetative phase: period from birth to maturation of reproductive systems.
(ii) Reproductive phase: period when the reproductive systems have matured and ready to produce offspring.
(iii) Senescence: period when the organism starts growing old and starts degrading.
