Archean and Proterozonic which are both broken into early middle and late periods
Homeostasis can be defined as the state of maintenance of the constant internal conditions by the living organisms. The homeostasis is maintained by the body so that it may function properly. The homeostasis will be disturbed by the reduced intake of the food and water. Healthy intake of water and food is essential in maintaining the homeostasis of the body. The elevated or depressed blood pH along with extreme body temperatures will also disturb the homeostasis of the body making the person sick. Moreover, certain infectious organisms also alters the homeostasis of the body.
Hence, all the options are correct.
they are both two types of grasslands
Answer:
b) At equilibrium, the species composition of an island will not change.
Explanation:
The Theory of Island Biogeography written by Robert H. MacArthur and Edward O. Wilson (1967) is an essential book for any professional working in biogeography, biodiversity, ecology, conservation and related fields. The theory of island biogeography states that species diversity on islands tends to approach a dynamic equilibrium due to the balance between colonization (inmigration), speciation and extinction. At equilibrium, the species composition of an island will change, precisely at the time that immigration and extinction processes maintain the number of species in a dynamic equilibrium, thereby maintaining species diversity. In this case, the colonization rate represents a function of distance to the continent (or other islands), the extinction rate is a function of the size of the island and habitat heterogeneity, and speciation is a function of time. This book also contains a series of useful considerations: 1-the number of species in an area is directly associated with the size of the area; 2-large islands support more diverse communities than small islands; 3-the viability of populations on island systems can be considered as a function of the island size and its proximity to the mainland (or other islands); and 4- when a habitat is lost the remaining fragmented area may lose some of its important species.
