Examples of discovery research that studies the river which is in the midst of the sea Cenote Angelita, Mexico. The river is located in a cave. Fresh water flowing in the middle of it is not mixed with the salty sea water. The study was conducted by Mr. Costeau. According to Mr. Costeau "to a depth of 30 meters, the water is fresh water (fresh), but if you dive to depths greater than 60 meters, the water becomes salty water, then you can see a" river "in essence, complete with trees and foliage leaves". After further research these rivers is a layer of hydrogen sulfide, which looks like a river.

POPULATION GROWTH MODEL

Gambar
 POPULATION GROWTH MODEL 1.     Exponential Growth Model In the exponential growth model, population increase over time is a result of the number of individuals available to reproduce without regard to resource limits Some assumptions are used in predicting population growth Exponential, that is: 1. Constant birth and death rate. 2. There is no genetic structure. 3. There is no structure of age difference and size. 4. No time delay. Let N denote the size of a population and t denote time. Then Nt is the number of individuals in a population at time t. Picture 1. Curve of Exponential Growth Model 2.         Logistic Growth Model Logistic model is used because in reality in nature that big size, the population depends on its density, so that the rate of birth and death rate are not constant (Haberman, 1977). Inpopulations with high density, each individual has few available resources and the ...

Biological Diversity - the great variety of life Biological diversity can be quantified in many different ways. The two main factors taken into account when measuring diversity are richness and evenness. Richness is a measure of the number of different kinds of organisms present in a particular area. For example, species richness is the number of different species present. However, diversity depends not only on richness, but also on evenness. Evenness compares the similarity of the population size of each of the species present. 1. Richness The number of species per sample is a measure of richness. The more species present in a sample, the 'richer' the sample. Species richness as a measure on its own takes no account of the number of individuals of each species present. It gives as much weight to those species which have very few individuals as to those which have many individuals. Thus, one daisy has as much influence on the richness of an area as 1000 buttercups...
