Trees are perennial, woody plants characterized by their elongated stems, called trunks, which support branches and leaves. They play a crucial role in the ecosystem by providing habitat and food for various species, contributing to soil health, and producing oxygen through photosynthesis. Trees come in diverse forms and sizes, growing in a variety of environments across the globe.
The ecological importance of trees extends beyond their role as oxygen producers. They help mitigate climate change by sequestering carbon dioxide, reduce soil erosion by anchoring the soil with their roots, and regulate the water cycle by facilitating precipitation and maintaining watershed health. Additionally, trees enhance the beauty of landscapes and are vital for cultural and recreational activities.
