  • Living organisms such as plants extract materials like water and mineral ions from the environment for growth.
  • Nutrients from the soil are absorbed by plant roots.
  • These nutrients are transferred to animals through feeding.
  • Nutrients move from plants to aphids, then to ladybirds, and finally to birds through the food chain.
  • Materials used by organisms are recycled, preventing the depletion of resources.
  • Recycling processes include trees shedding leaves, animals excreting waste, and the decomposition of dead organisms.
  • These recycling processes ensure the continuous availability of materials for future organisms.
