External fertilization means that it takes place outside of the body, which also means the eggs and sperm are exposed to a lot more danger, and that the chances of a successful fertilization are lower.
Because of this, the amounts produced are much higher to give a reasonable chance that there will be offspring.

Is number of eggs prodced by oviparous and young ones produced by viviparous same?
oviparous animals live in more harsh environment and thus lay large number of eggs compared to viviparous animals. this high multiplication ensures that few of the eggs get fertilized (external fertilization) and develop into young once.
Animals that undergo external fertilization?
Animals that undergo external fertilization include many fish, amphibians, and aquatic invertebrates. Species like salmon, frogs, and sea urchins release eggs and sperm into the water, where fertilization occurs outside the body. This method often requires moist environments to prevent gametes from drying out and to increase fertilization success. visit our website: www. sathayatravels .com/about

How do cold blooded animals reproduce?
Cold-blooded animals reproduce through a process that typically involves internal or external fertilization. Some lay eggs, while others give birth to live young. They often rely on environmental cues, such as temperature, to determine when to reproduce.
How is the number of eggs an animal produces related to its form of fertilization and development?
Animals that reproduce through external fertilization typically produce a large number of eggs because there is lower chance of each egg surviving to adulthood. In contrast, animals that reproduce through internal fertilization often produce fewer eggs but invest more energy and resources in caring for them due to higher survival rates. This relationship is influenced by the species' reproductive strategy and environmental conditions.
What adaptations in aquatic animals help ensure that external fertilization will occur?
produce more eggs
What are the only vertebrate animals that have external fertilization and lay eggs in water?
There are thousands of such vertebrates as bony fishes .
What is the difference between internal and external fertilisation in animals?
Internal fertilization is like animals having sex....the egg is fertilized on the inside. External is when the egg is fertilized on the outside (like when frogs lay eggs and they need to be fertilized before they can hatch).
Does a hawk reproduce internally or externally?
The term "external reproduction" for higher animals means in eggs rather than internally. So the hawk reproduces externally, laying and hatching its eggs.
Why do women have eggs but give live birth?
all animals have eggs, but it depends their fertilization development type (which is either internal or external). Humans are mammals, and all mammals give live birth unless it is a monotreme, which lays eggs.
Is number of eggs prodced by oviparous and young ones produced by viviparous same?
oviparous animals live in more harsh environment and thus lay large number of eggs compared to viviparous animals. this high multiplication ensures that few of the eggs get fertilized (external fertilization) and develop into young once.
Why is it important that animals that have external fertalisation produce a lot of eggs?
Take any animal that has external fertilisation. Each of these eggs has only a small chance a) being fertilised in the first place and b) actually surviving to hatch, so to speak. So many eggs are laid at once to increase the chance that there will be a decent amount of offsping. Also bear in mind that alot of the offspring won't make it past the early stages of life due to predators etc.
How many eggs do Portuguese Man of War lay?
Portuguese Man o' War do not lay eggs. They are marine animals known as siphonophores, made up of different specialized animals called zooids working together as one organism. They reproduce by releasing sperm and eggs into the water for external fertilization.
Are jellyfish external or internal fertilization?
External. In most cases, adults release sperm and eggs into the surrounding water, where the (unprotected) eggs are fertilized and mature into new organisms.
Is a monkeys fertilization internal or external?
Internal because they give birth and not lay eggs. If they lay eggs, they would be like a chicken. ~Savannah B.
What is the word for animals laying eggs?
Oviparous animals lay eggs.
Do bees use internal or external development?
External, because they lay eggs.
