  • What consequences do biogeochemical cycles have on ecosystems?
    Imbalances can lead to nutrient deficiencies or toxicities, affecting plant growth and productivity.
  • What do you call the nutrients that make up the building blocks of life and that are required in large quantities?
    macronutrients
  • What do you call the nutrients that make up the building blocks of life and that are required in small quantities?
    micronutrients
  • How would the alteration of their biogeochemical cycles affect living beings?
    These alterations can create a cascade of effects that compromise the health of ecosystems and the organisms that depend on them.
  • How could we counteract the consequences of ecosystem disruption?
    Taking care of the planet by...
  • Where can we find Lithium?
    In batteries
  • How do biogeochemical cycles contribute to the maintenance of life on Earth?
    Biogeochemical cycles are related to the transfer of nutrients through the organisms and abiotic components of the environment. They describe the routes taken.
  • Where can we find Oxygen?
    Air
  • Where can we find Sulfur?
    Eggs
  • How do human activities affect biogeochemical cycles?
    Increased fossil fuel combustion releases large amounts of CO2, contributing to climate change. Industrial activities release sulfur dioxide into the atmosphere
  • What are examples of macronutrients?
    water, carbon, hydrogen, nitrogen, phosphorus, sulfur, calcium
  • What are the six main elements that make up living beings on Earth (C, H, O, N, P, S)?
    Carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur
  • What are the abiotic components of the environment?
    Climate, water, sunlight, air.
  • What are examples of micronutrients?
    zinc, iron, selenium, iodine
  • What are examples of nutrients that are transferred through biogeochemical cycles?
    carbon, nitrogen, phosphorus, water
  • Where can we find Potassium?
    Fruits and vegetables
