What is the difference between external and internal fertilization in short answer type question ?

Question

Answer

Answer

The difference between external and internal fertilization
External fertilization:-the fussion of male gametes and female gametes takes place in the outside of the female body is known as external fertilization
example:-frog , fish etc

Internal fertilization:-the fusion of male gametes and female gametes takes place in the inside of the female body is known as internal fertilization
example:-human,cow, dog, cat etc

Answer

External Fertilization:
External fertilization is a reproductive process in which the fusion of gametes (egg and sperm) occurs outside the body of the parent organisms. This type of fertilization is usually observed in aquatic organisms such as fish, amphibians, and some invertebrates.

Process:
In external fertilization, the female releases a large number of eggs into the water, while the male releases a large quantity of sperm. The eggs and sperm meet in the surrounding water and fertilization takes place externally. This process requires the coordination of both male and female organisms to release their gametes at the same time and place.

Advantages:
1. Increased chances of fertilization: By producing a large number of eggs and sperm, the organisms increase the likelihood of successful fertilization.
2. Genetic diversity: External fertilization allows for a wide range of genetic combinations, as the gametes from different individuals can mix freely in the water.
3. Lower energy expenditure: Since the reproductive process occurs outside the body, organisms do not need to invest as much energy in the development of specialized reproductive structures.

Disadvantages:
1. Vulnerability: The eggs and sperm released into the water are exposed to various environmental factors, increasing the vulnerability of the offspring to predation or other risks.
2. Wastage of gametes: The vast majority of gametes released during external fertilization fail to result in successful fertilization and offspring, leading to a significant wastage of reproductive potential.
3. Lack of parental care: External fertilization does not involve any parental care, which can be disadvantageous for the survival and development of the offspring.

Internal Fertilization:
Internal fertilization is a reproductive process in which the fusion of gametes occurs inside the body of the female organism. This type of fertilization is observed in many terrestrial organisms, including mammals, birds, reptiles, and some fish and invertebrates.

Process:
In internal fertilization, the male deposits sperm into the female's reproductive tract, where fertilization takes place. This can occur through various mechanisms such as copulation, mating, or direct transfer of sperm. Internal fertilization allows for better control of the conditions necessary for successful fertilization and development of the offspring.

Advantages:
1. Increased protection: Internal fertilization provides better protection for the developing embryos as they are sheltered and provided with nutrients within the female's body.
2. Higher survival rates: The parental care associated with internal fertilization, such as incubation and nurturing, increases the chances of survival and successful development of the offspring.
3. Reduced wastage of gametes: Internal fertilization reduces the wastage of gametes as the sperm is directly deposited into the female's reproductive tract, minimizing the chances of gamete loss.

Disadvantages:
1. Limited genetic diversity: Internal fertilization restricts the genetic diversity compared to external fertilization, as the gametes from only two individuals are involved.
2. Higher energy expenditure: Internal fertilization requires the development of specialized reproductive structures and behaviors, leading to higher energy expenditure by the organisms.
3. Complexity and dependency: Internal fertilization often requires complex reproductive behaviors and mechanisms, increasing the dependency on specific mating partners and environmental conditions.

In conclusion, external fertilization occurs outside the body of the parent organisms, while internal fertilization occurs within the
