Question 1

Which level of biological organization is defined as a community of organisms interacting with their physical environment?

  • Type: mcq
  • Options: A) Population, B) Organism, C) Ecosystem, D) Tissue
  • Correct Answer: C
  • Explanation: An ecosystem includes both the biotic (living) and abiotic (non-living) factors in a specific area.
  • Hint: It includes the plants, animals, soil, and weather.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Application: A scientist discovers a mysterious object. It can move when touched and it "grows" in size by absorbing water, but it cannot reproduce and does not have cells. Is this object a living organism according to the biological definition? Justify your answer.

  • Solution: No, it is not alive. To be considered a living organism, an object must meet all the characteristics of life. While it responds to stimuli and grows, the lack of cells and the inability to reproduce disqualify it.
  • Hint: Use the "CHARGER" criteria.

💡 Hint: Use the "CHARGER" criteria.

Challenge 2 Hard

Ethics & Innovation: How can the study of Genetics lead to both a positive medical breakthrough and a potential ethical dilemma?

  • Solution: A positive breakthrough could be gene therapy to cure a hereditary disease. An ethical dilemma might involve "designer babies" or the privacy of an individual's genetic data.
  • Hint: Think about the power to change DNA.

💡 Hint: Think about the power to change DNA.
