Syllabus
2026–2028
Course
Biology 0610

Exam points

  • explain entanglement, choking, blocked digestion or impaired movement in affected animals
  • trace microplastics from producers through fish to higher consumers in an aquatic food chain
  • interpret plastic-waste data and distinguish accumulation from biological breakdown
