Why do Plants and Animals Need Nutrition?

Plants and animals need nutrition for different reasons.

Plants need nutrition to survive and grow. They use nutrients from the soil, water, and air to produce energy and build their structure. Nutrients such as nitrogen, phosphorus, and potassium are essential for plant growth and development. Plants also require other essential elements such as calcium, magnesium, and sulfur, which play important roles in photosynthesis, respiration, and other metabolic processes. Without proper nutrition, plants may not be able to grow, produce flowers or fruit, or resist disease and environmental stress.

Animals need nutrition for several reasons, including growth, maintenance, and repair of body tissues, and for energy to carry out vital bodily functions such as breathing, circulation, and digestion. Animals require various macronutrients such as carbohydrates, fats, and proteins, as well as micronutrients such as vitamins and minerals, which are essential for normal physiological functions. Different animals have different nutritional requirements depending on their species, age, and activity level. A lack of proper nutrition can lead to growth and developmental issues, poor health, and decreased performance.

In summary, both plants and animals require proper nutrition to survive, grow, and carry out their physiological functions. The nutrients they need can vary depending on the species and their stage of development.
