Study Notes

  • The following study notes cover a range of topics related to the environment and ecosystems, including their components, human impact, and ecological studies

Medio Ambiente (Environment)

  • The environment encompasses both natural and cultural components
  • Natural components are:
    • Climate
    • Geography
    • Fauna
    • Flora
  • Cultural components are:
    • Objects made by humans
    • Socioeconomic activities

Actividades Humanas y el Ambiente (Human Activities and the Environment)

  • Consequences of human activities on the environment include:
    • Extinction of species
    • Water contamination
    • Displacement of animal and human populations due to habitat destruction

Ecología (Ecology)

  • Ecology studies the relationship between living beings and the environment

Ecosistema (Ecosystem)

  • An ecosystem is defined as the physical environment where living beings live and the relationships they establish among themselves and with their environment
  • It comprises a set of living beings that inhabit a part of the biosphere

Componentes del Ecosistema (Ecosystem Components)

  • The two main components of an ecosystem are:
    • Biotopo
    • Biocenosis

Biotopo

  • The biotopo's components are:
  • Physical environment of the ecosystem
  • Environmental conditions of the ecosystem
  • The term "topo" in biotopo relates to topography

Cuadro Sinóptico del Ecosistema (Ecosystem Synoptic Chart)

  • In the synoptic chart, an ecosystem represents the sum of its components and their relationships

Medio Físico del Biotopo (Physical Environment of the Biotope)

  • The physical environment of the biotope is where the living beings of an ecosystem reside
  • Matter and energy are exchanged in this environment
  • The two types of physical environments are:
    • Aquatic
    • Terrestrial

Condiciones Ambientales del Biotopo (Environmental Conditions of the Biotope)

  • The environmental conditions of a biotope involve function
  • Abiotic factors, which are chemical and physical factors, determine the environmental conditions of the biotope

Factores Abióticos (Abiotic Factors)

  • Abiotic factors, with their respective functions within an ecosystem, include:
    • Light: the main source of energy for ecosystems, allowing photosynthetic organisms to exist
    • Water: involved in the water cycle
    • Temperature: determines which species inhabit an ecosystem
    • Wind: air in movement
    • Atmospheric pressure: The force exerted by the weight of air in an area
