lifslengd

Lifslengd is a Swedish word that translates to "lifespan" in English. It refers to the period of time that an organism lives, from its birth to its death. This concept is fundamental in biology, ecology, and demography, as it influences population dynamics, evolutionary processes, and the overall health of species.

Factors influencing lifespan are diverse and can include genetics, environment, diet, and exposure to disease or predation. In humans, lifespan is often measured in years and is a key indicator of public health and socioeconomic development. Different species have vastly different lifespans, ranging from a few days for some insects to centuries for certain trees and marine organisms like the ocean quahog.

The study of lifespan, known as gerontology, seeks to understand the biological mechanisms of aging and to potentially extend healthy lifespans. Variations in lifespan within a population can also provide insights into the selective pressures and adaptive strategies of a species. Understanding lifespan is crucial for conservation efforts, resource management, and for comprehending the life cycles of all living things.
