In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
A life cycle ritual is a ceremony to mark a change in a person's biological or social status at various phases throughout life. [1] Such practices are found in many societies and are often based on traditions of a community. [1] Life cycle rituals may also have religious significance that is stemmed from different ideals and beliefs. [1]
Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies.
All organisms follow a specific sequence in their development, [9] beginning with gestation and ending with death, which is known as the life cycle. Events in between usually include birth , childhood , maturation , reproduction , and senescence , and together these comprise the life history strategy of that organism.
Trillium grandiflorum in the foreground and the smaller Thalictrum thalictroides in the background are both spring ephemerals of North American deciduous forests. An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are favorable.
Life cycle interpretation is a systematic technique to identify, quantify, check, and evaluate information from the results of the life cycle inventory and/or the life cycle impact assessment. The results from the inventory analysis and impact assessment are summarized during the interpretation phase.
Another example of a bivoltine species is Cyclosa turbinata which is known to reproduce once in the late spring and once again in the fall. The Dawson's burrowing bee is an example of a univoltine insect of the order Hymenoptera. The brood of one winter will remain dormant underground until the following winter, and then will surface from their ...
