Offsprings of oviparous animals are at greater risk as compared to offsprings of viviparous animals because -

Options

A. Proper embryonic care and protection is lesser
B. Embryo is not developed
C. Progenies are with more variation
D. Progenies are larger

Answer

**Step-by-Step Solution:**

1. **Understanding Oviparous and Viviparous Animals:**
- Oviparous animals are those that lay eggs, and their offspring develop outside the mother's body. Examples include birds, reptiles, and many fish.
- Viviparous animals give birth to live young, with the offspring developing inside the mother's body. Examples include mammals.

2. **Development Environment:**
- In oviparous animals, the embryos develop inside eggs, which are often laid in the environment. This exposes them to various risks such as predation, environmental changes, and lack of parental care.
- In viviparous animals, the embryos develop within the mother's womb, providing a controlled and protected environment that shields them from external threats.

3. **Risks to Offspring:**
- Oviparous offspring face higher risks due to exposure to predators and environmental hazards. The eggs are often left unattended after laying, increasing the likelihood of predation.
- Viviparous offspring benefit from the mother's protection, receiving nourishment and a stable environment until they are ready to be born. This significantly reduces their risk of mortality.

4. **Care and Protection:**
- Oviparous animals generally provide less care and protection for their eggs compared to viviparous animals, which often care for their young after birth.
- The lack of care in oviparous species leads to higher mortality rates among their offspring.

5. **Conclusion:**
- Therefore, the offspring of oviparous animals are at greater risk compared to those of viviparous animals due to the lack of protective environments and parental care.

**Final Answer:**
Offspring of oviparous animals are at greater risk as compared to offspring of viviparous animals because they develop in eggs that are exposed to environmental hazards and predators, whereas viviparous offspring develop inside the mother's womb, providing them with a safer and more nurturing environment.
