What is the most advantageous for developing animals oviparity ovoviviparity or the viviparity?

After development, live birth takes place. This process is much more energy-expensive than oviparity. Although this often leads to a lower number of offspring produced, higher parental investment allows them to have higher survival rates.

Why is viviparity advantages over oviparity?

Viviparity (give birth to live young) is good because the embryo can develop inside the mother where temperatures and nutrients are stable, thus enabling the young a greater chance to survive.

What is the difference between oviparity and over viviparity?

The main difference between oviparous and viviparous animals is that oviparous animals do not undergo any embryonic development inside the mother whereas viviparous animals develop into a young animal inside the mother. This means oviparous animals lay eggs. These eggs develop and hatch into young individuals.

What is the difference between viviparous and Ovoviviparous?

Viviparous animals undergo internal fertilization and the embryo develops inside the mother until a young one is born. The ovoviviparous animals produce eggs but the eggs develop inside the mother and a live organism is born. However, unlike viviparous animals, ovoviviparous animals do not have a placenta.

What are the advantages and disadvantages of internal fertilization?

When a sperm fertilizes an egg within the female, it is known as internal fertilization. The advantages of internal fertilization are that the fertilized egg is protected from predators and harsh environments, thus ending in higher chances of survival. Also, there is a lesser chance of desiccation of gametes.

What is the description of ovoviviparity?

Definition of ovoviviparous : producing eggs that develop within the maternal body (as of various fishes or reptiles) and hatch within or immediately after release from the parent.

What is an advantage of viviparity?

Egg-laying is inefficient in allowing huge losses and greatly limits the size of the newborn, although it has the advantage of causing little physiological upheaval to the mother. Viviparity, on the other hand, allows the growth of a much larger fetus, offers great protection and is highly efficient.

What is the advantage of viviparous organisms over oviparous organisms Class 12?

The Embryo absorbs nutrients from the mother’s body during its foetal stage. Eggs are exposed to several risks and damages which reduces survival rate for Oviparous Organisms. The chances of survival are high in Viviparous Animals as Embryo stays fully protected inside the mother’s womb.

What is the difference between oviparous and viviparous animals give one example of each?

What is the difference between the VIVIPAROUS ANIMALS and the OVIPAROUS ANIMALS?…

Oviparous Animals Viviparous Animals
Example Oviparous animals are birds, some reptiles, and amphibians. Viviparous animals are humans, lion, horse, dog, elephant, etc.

Why is oviparous a disadvantage?

Being an oviparous has it on disadvantages which is they have to protect and hide their eggs during development because the eggs produce is so fragile and also to protects those eggs from predators (Mills,2018)Viviparous animals refer to the animals that give birth to offspring.

Is oviparous or viviparous better?

Chances for Survival Oviparous Animals: Since oviparous animals lay eggs on the environmental surfaces, the chances of survival are less. Viviparous Animals: Since viviparous animals directly deliver young ones, the chances of survival are more.

What are the advantages of internal fertilization over external fertilization?

The advantage that internal fertilisation has over external fertilisation is that in internal fertilisation : (a) new off-springs are exactly like the parent. (b) production of large numbers of gametes is unnecessary. (c) copulation and fusion of gametes is passive.
