👉 sessility is a biological concept that refers to the ability of an organism to adapt and survive in a changing environment. It involves the organism's ability to adjust its behavior, physiology, or other characteristics to fit within a new or altered environment. This adaptation can be achieved through various mechanisms such as changes in gene expression, changes in metabolic rates, or changes in physical traits. The term is often used in ecology and evolutionary biology to describe how an organism has evolved to survive and thrive in its current habitat
