Fish eggs consumed as food are known as roe or caviar. Hens and other egg-laying creatures are raised throughout the world, and mass production of chicken eggs is a global industry. In 2009, an estimated 62.1 million metric tons of eggs were produced worldwide from a total laying flock of approximately 6.4 billion hens. [3]
Typically large numbers of eggs are laid at one time (an adult female cod can produce 4–6 million eggs in one spawning) and the eggs are then left to develop without parental care. When the larvae hatch from the egg, they often carry the remains of the yolk in a yolk sac which continues to nourish the larvae for a few days as they learn how ...
In fact, they say that “all foods made from meat, poultry, seafood, beans and peas, eggs, processed soy products, nuts, and seeds are considered part of the protein foods group.”
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).

The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such ...
According to the Farralones Institute's report from 1976, raising rabbits, and chickens (on a well-considered approach) for food can still be quite sustainable. [6] As such, the production of meat and other produce, such as eggs, may still be considered environmentally friendly (if this is done in an industrial, high-efficiency manner).
Organic egg production is the production of eggs through organic means. In this process, the poultry are fed organic feed. According to the United States Department of Agriculture, organic means that the laying hens must have access to the outdoors and cannot be raised in cages. [1] Only natural molting can occur within the flock; forced ...
Monotreme. Monotremes (/ ˈmɒnətriːmz /) are mammals of the order Monotremata. They are the only known group of living mammals that lay eggs, rather than bearing live young. The extant monotreme species are the platypus and the four species of echidnas. Monotremes are typified by structural differences in their brains, jaws, digestive tract ...
