If all the plants of the world die, all the animals will die due to shortage of:

A. Food
B. Water
C. Heat
D. Oxygen 

🧠 Explanation:

If all plants die, animals will die due to oxygen shortage, as plants produce oxygen via photosynthesis. For biology students, this highlights ecosystem interdependence, making it a key topic for studying environmental science, biology, and ecological balance. Oxygen is vital for animal respiration. Understanding this reveals the critical role of plants in survival. It’s essential for analyzing ecosystems, biodiversity, and environmental conservation. Studying this scenario offers insights into how plant loss impacts life, crucial for environmentalists, biologists, and policymakers addressing deforestation, climate change, and the preservation of ecosystems for global survival and sustainability.
