  2. Provision of oxygen: during the process of photosynthesis, plant release oxygen into the atmosphere which is needed by animals for respiration.
  3. Recycling of water: through the process of transpiration occurring in leaves of plants, water is recycled in nature.
  4. Provision of other products such as timber, fibers, medicines, dyes, oils, and rubber.
