Based on the analysis of the image and biological principles, the two things that both plants and animals need to live are
Air and
Water.
Here is the reasoning for this solution:
1.
Air: Both plants and animals require air for survival, although they use it in different ways.
*
Animals need oxygen from the air for cellular respiration, a process that releases energy from food.
*
Plants need carbon dioxide from the air for photosynthesis, the process by which they create their own food. They also perform respiration (like animals) and require oxygen, especially at night when photosynthesis stops.
2.
Water: Water is essential for all known forms of life.
*
Animals need water for hydration, digestion, circulation, and regulating body temperature.
*
Plants need water for photosynthesis, transporting nutrients from the soil, maintaining cell structure (turgor pressure), and cooling through transpiration.
While other items like "Food," "Sun," and "Space" are also important, they are not universally required by both in the same way:
*
Food: Animals must consume other organisms for energy, while plants produce their own food via photosynthesis.
*
Sun: Plants absolutely require sunlight for photosynthesis. While many animals benefit from the sun (for warmth, vitamin D, etc.), some animals live in environments without direct sunlight (e.g., deep-sea creatures, cave-dwellers) and can survive without it.
*
Shelter/Soil: These are specific to certain types of animals or plants, not universal requirements for all.
Therefore,
Air and
Water are the most fundamental and universally necessary resources for the survival of both plants and animals.
