The four stages of the life cycle of an animal are birth, growth, reproduction and death. ... Some animals can reproduce asexually, but most animals reproduce through sexual reproduction, which requires male and female gametes. After aging, animals end their life cycles by dying.

What are the reproductive stages of animals?
Most animals reproduce through sexual reproduction, but some animals are capable of asexual reproduction through parthenogenesis, budding, or fragmentation. Following fertilization, an embryo is formed, and animal tissues organize into organ systems; some animals may also undergo incomplete or complete metamorphosis.
What is the stage of development when an organism can reproduce?
For example, upon reaching adulthood, organisms can reproduce and transfer their genetic information to their offspring. Animals engage in behaviors that increase their chances for reproduction, and plants may develop specialized structures and/or depend on animal behavior to accomplish reproduction.
Do all life cycles start as an egg?
All life cycles have a few things in common: they start with seeds, eggs, or live birth, then involve multiple steps including reproduction, and then they end in death.
What animals have 3 stages in their life cycle?
Some animals, such as chickens, cockroaches and frogs, have three stages in their life cycles. The three stages are the egg, the young and the adult. The young of some of these animals look different from the adults. During the egg stage, the chick develops inside the egg.
How do animals reproduce?
To reproduce, animals need a male and female. Together they can create offspring, or babies. Some animals, such as chickens, fish and snakes, lay eggs which contain their offspring. Other animals, including humans, tigers and sheep, grow their babies inside them until they are developed enough to be born.
What animals reproduce external fertilization?
Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce.
What is the life cycle of an organism?
A life cycle is defined as the developmental stages that occur during an organism's lifetime. ... In general, plants and animals go through three basic stages in their life cycles, starting as a fertilized egg or seed, developing into an immature juvenile, and then finally transforming into an adult.
How do animals grow and reproduce?
The whole process of sexual reproduction in animals begins with the formation of sperm from the male and eggs from the female. Next, the sperm and egg join together to form a zygote. Finally, the zygote grows and develops to become a baby animal.
How are the life cycles of animals alike and different?
Different classes of animals have different life cycles. Most classes of animals, including fish, mammals, reptiles, and birds, have fairly simple life cycles. ... Amphibians and insects have more complicated life cycles. These animals undergo a metamorphosis (a significant change in their physical structure or habits).
What stages do life cycles include?
There are five steps in a life cycle—product development, market introduction, growth, maturity, and decline/stability. Other types of cycles in business that follow a life cycle type trajectory include business, economic, and inventory cycles.
What is the first stage in the life cycle of egg laying animals?
egg: unborn stage. larva: young stage -- this is when most of the feeding is done. pupa: inactive (no feeding) stage between larva and adult stages. adult: final, breeding stage.
Does a beetle have a 3 stage life cycle?
There are two groups of insects. This group has a 3-stage life cycle. ... In the second group, including beetles, butterflies, moths, flies, bees, and wasps, the young stages are very unlike the adults.
Does a frog have a 4 stage life cycle?
The life cycle of a frog goes through FOUR stages of life. They undergo metamorphosis (changes and grows at each stage).
Does a grasshopper have a 4 stage life cycle?
They go through “Incomplete Metamorphosis,” in which each stage looks similar to an adult grasshopper but adds a few changes each time the young grasshopper sheds its skin. On the other hand, COMPLETE METAMORPHOSIS has FOUR different stages i.e. the egg, the larva, the pupa and the adult.
