A is the place where each of the animal species lives . This place has the right conditions for that animal to live there . Animals can live on land or underwater . Complete the information . Animals that live in the terrestrial ecosystem can breathe from our air . They live on the ground , in places like forests , grasslands and deserts , among others . Animals that can fly also live in the terrestrial habitat , since they rest and make their nests in the terrestrial area . Complete the information . The is close to the polar zones , therefore it has an extremely cold climate . It is so cold that the trees hardly survive . The soil remains frozen for much of the year . In the summer it thaws , but only a few centimeters . Complete the information . The simplest definition of an ecosystem would be that of a highly complex biological system that includes each and every one of the different interactions that take place , both between living things and between them and the in which they are found . Complete the information . Mixed ecosystems : These can be constituted by the presence of land and water , or land and air ( air - ground ecosystems ) . The main types of ecosystems that exist in nature are : ? Wetlands . ? Mangroves . ? Marshes . ? Costs . Complete the information . Artificial ecosystems are increasingly and rapidly , various artificial ecosystems exist throughout the planet . For this reason , we can also refer to artificial ecosystems by the name of or humanized ecosystems , as well as non - natural ecosystems . Complete the information . The main types of ecosystems are : ? Urban ecosystems . ? Agricultural or agricultural ecosystems . ? Dam or reservoir ecosystems . Complete the information . There are three types of biological adaptation to the environment in which one lives : Morphological or structural , or functional and Ethological or behavioral . Complete the information . Different inter - specific relationships are depredation ? parasitism ? ? symbiosis ? food chains ? food networks ? the balance between living beings . Complete the information . Physical abiotic factors : They are those related to the forces acting on ecosystems on Earth , for example : sunlight , temperature , atmospheric pressure , climate , relief and Biotic factors are generally organized in , that is , groups of living things of the same type that share a specific habitat . Complete the information . Sound is any phenomenon that involves the propagation of mechanical waves , generally through a fluid that is generating the movement of a body . Complete the information . The tone or height is the quality that allows us to distinguish between a high or high sound and a low or high sound . For a pure sound , the tone is mainly determined by the , although it can also change with the pressure and the envelope . Complete the information . The timbre of a sound is the quality by virtue of which we can distinguish two sounds of equal frequency and intensity emitted by two different sound sources . The is due to the fact that generally a sound is not pure and depends mainly on the spectrum . But it also depends greatly on the envelope and the frequency . Complete the information . The physical duration of a and the perceived one are closely related although they are not exactly the same . The perceived duration is that time interval in which the sound persists without discontinuity . Complete the information . Heat is a form of energy exchange between the system and its surroundings due to a temperature difference . systems do not have heat , they have energy , and one of the ways they exchange this energy is heat .
