Complete the information. 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 ______________ 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 _______________________ 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 _____________ 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 timbre 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.
