What are the different ways by which animals reproduce
Answers
Answer:
• The period of time for which a living organism lives is called lifespan.
• Reproduction is the process by which living things produce more of their own
kind.
• Animals reproduce in two ways:
1. Some animals reproduce by giving birth to their young ones.
2. Some animals produce their young ones through eggs.
• Viviparous Animal : The animals which give birth to their young ones are called
Viviparous animals. Eg, deer, lion and cow. The young babies of these animals feed
on their mothers milk till they learn to eat other food. Such animals are called
mammals.
• Oviparous Animal: The animals which give birth to their young ones through eggs
are called oviparous animal.Eg, fishes and frogs.
• According to habitat, we can divide oviparous animals into three categories:
• Aerial Oviparous animals - Birds
• Terrestrial Oviparous animals - Insects and snakes
• Aquatic Oviparous animals- Fishes and frogs.
• Aerial Oviparous animals
• The birds such as hen, crow and parrot lay eggs. They bear their young ones in
hard shelled eggs which hatch after some time. Adult birds sit on the eggs for a
few days to keep them warm till they hatch. This is called as Incubation.
Answer:
The next stage is the larva. This is also called a caterpillar if the insect is a butterfly or a moth. The job of the caterpillar is to eat and eat and eat.
Mammals
Birds reproduce by internal fertilization, during which the egg is fertilized inside the female. Like reptiles, birds have cloaca, or a single exit and entrance for sperm, eggs, and waste. The male brings his sperm to the female cloaca.
The three stages are egg, nymph, adult. When the young hatches they look similar to the adults except they are smaller, and don't have wings. Examples of insects with a 3 stage life cycle include: True bugs, dragonflies, grasshoppers, crickets and earwigs.
Explanation:
Nymph, in Greek mythology, any of a large class of inferior female divinities. ... The nymphs were usually associated with fertile, growing things, such as trees, or with water. They were not immortal but were extremely long-lived and were on the whole kindly disposed toward men.
Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young (called a larva instead of a nymph) is very different from the adults. It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.
Just as in plants, there are two modes by which animals reproduce. These are: (i) Sexual reproduction, and (ii) Asexual reproduction. in humans and study the process of reproduction in them.
