Question: Describe the environmental variables and explain their importance to plants and animals.
Environmental variables are the physical and chemical factors that affect the living conditions of plants and animals. They include temperature, light, water, soil, air, and nutrients. Environmental variables are important to plants and animals because they determine their growth, survival, reproduction, and distribution. For example, plants need light to perform photosynthesis, water to transport nutrients and minerals, and soil to anchor their roots and provide minerals. Animals need temperature to regulate their body functions, water to maintain hydration and metabolism, and air to breathe and exchange gases. Environmental variables can also influence the interactions between plants and animals, such as pollination, herbivory, predation, and symbiosis.
