The fundamental difference of endodermic and esxothermic organisms is the ability of the organism to regulate and maintain its body temperature. Ectodermic is an organism that can not maintain a constant body temperature and always needs heat around to regulate their body heat. Therefore, ectodermic activity is strongly influenced by changes in ambient temperature. For example, many reptiles get hot with the sun in the sun and while cooling their bodies to move to a shelter, if necessary.  Endothermic is an animal that can maintain a fairly constant body temperature under various ambient temperatures from intense desert heat to the Arctic cold. This constant temperature range allows the endothermic to survive in a very wide geographical and ecological area of ​​the earth. All mammals and birds are endothermic, and they require energy to the production process of heating and cooling. Especially they get this energy with the digestion of the food they eat. Their b...

Ecological Hierarchy Ecology Organismal Organismal ecology that includes the subdisciplines of ecology of physiology, evolutionary ecology, and behavioral ecology, studies how structures, physiology, and (for animals) behavior of organisms meet the challenges of the environment. Example: How to regulate the body temperature of lizards in habitats with different heights? Ecology population The population is an individual group of the same species living in a region. Population ecology analyzes factors affecting population size and how and why populations change over time. Example: Why does the Sumatran Tiger population continue to decline over time?  Ecology Community The community is a population group of a number of different species in a region. Community ecology examines how intercountry interactions, such as predation and competition, affect community structures and organizations. Example: What abiotic factors affect the diversity of plants ...

Fauna Land The soil groups are numerous and diverse, ranging from Protozoa, Rotifera, Nematodes, Annelids, Molluscs, Arthhropods, to Vertebrates. Ground animals can also be grouped on the basis of body size, presence on the ground, the habitats it chooses, and its feeding activities. Based on the size of the body, the soil animals are grouped into microfauna, mesofauna, and macrofauna. The size of the microfauna ranges from 20 to 200 microns (including Protozoa, Nematodes which become micropredators for other microorganisms), mesophauna 200 microns up to 1 cm (eg Mikroarthropoda, Collembolan, Acarina, Termintes, Olgochaeta, and Ecnchytraidae which decompose major litter or organic material Other), and macrofauna more than 1 cm in size (Suin, 2012). Land fauna based on its presence on the ground, divided into (Wallwork, 1970): Temporary, ie animals that entered the land with the aim of laying, after the hatch and develop into adults, the animals will come out of t...
