Why there is different types of fertilization in animals?

In animals

Internal fertilization happens in the female body. External fertilization happens outside of the body. Mammals, birds, and reptiles use internal fertilization. Amphibians and most fish use external fertilization.

What fertilization is more common in land animals?

Internal fertilization occurs most often in land-based animals, although some aquatic animals also use this method.

Why do most aquatic animals use external fertilization and most land animals use internal?

For example, spawning is usually advantageous in aquatic environments because the eggs and sperm are able to float and drift through the water to one another. Internal fertilization tends to protect gametes, zygotes, and embryos of land animals from harsh conditions in the external environment.

What is fertilisation explain different types of fertilisation?

Fertilization is the process by which the male and female gametes fuse to form the zygote. There are two types of fertilization- External fertilization- It is the fertilization where the eggs are fertilized outside the body of the organisms. They occur mostly in wet environments.

Why do animals with external fertilization almost always live or reproduce in water?

External fertilisation of the female gamete by the male gamete takes place mostly in water; because water facilitates: extended period of gamete survival and easy movement of sperms towards egg.

What is the difference between external and internal fertilization quizlet?

External fertilization is when eggs are released by a female into the environment and later fertilized with a male's sperm. Internal fertilization is when sperm are deposited in or near a female's reproductive tract and fertilization takes place within the reproductive tract.

What is the difference between external and internal?

The difference between internal and external is that anything internal is on the inside of something, whereas anything external is on the outside of something.

Why most of the terrestrial animals fertilization takes place internally?

Answer : The environment on terrestrial land keeps on changing than that of the marine environment. So inorder to increase the survival chance of the fertilization (internal environment is nearly constant) terrestrial animals' fertilization takes place internally.

How are mammals different from other groups of animals?

Mammals have hair or fur; are warm-blooded; most are born alive; the young are fed milk produced by the mother's mammary glands; and they have a more complex brain than other animals. 2. How do mammals feed their young? Mammals feed their young with milk produced by the mother in special organs called mammary glands.

Why do you think the eggs are found in the water where do you think fertilization happens?

External fertilization in animals usually occurs in water or in damp areas in a process called spawning. Moisture in the environment keeps the gametes from drying out. Moisture is also important so the eggs and sperm can move around freely, which lets them meet and fuse.

Why do you think that amphibians and many fish have external fertilization whereas lizards birds and mammals rely on internal fertilization?

Why do you think that amphibians and many fish have external fertilization, whereas lizards, birds, and mammals rely on internal fertilization? ... Lizards, birds, and mammals have adaptations that allow them to reproduce away rom a water environment.

How does the external fertilization in fish occur quizlet?

How does the external fertilization in fish occur? Eggs and sperm are deposited in the same area, usually in a protected place such as floating plants or other shallow, gravel areas. Define the term.
