Q.Why are the offsprings of oviparous animal at a greater risk as compared to offsprings of viviparous organisms?

Step 1. In oviparous animals, the young hatch from eggs laid outside the mother's body - once laid, the developing embryo is physically separate from the mother and is exposed directly to the external environment for its entire incubation period.

Step 2. This external development leaves oviparous eggs vulnerable to predation, temperature extremes, physical damage and other environmental hazards, with the mother often able to offer only limited or intermittent protection (such as guarding a nest) rather than continuous physiological support.

Step 3. In viviparous animals, by contrast, the young develops fully inside the mother's uterus and is nourished continuously through a placental connection, sheltered inside her body from external predators, weather and physical damage throughout its entire development, and is only born once it has reached a comparatively advanced, more self-sufficient stage. …

Compare where each type of offspring develops (outside vs inside the mother's body) and how that differen …

• Focusing only on predation risk while ignoring the placental nourishment advantage that viviparous offspring also receive. …
