Answer 1

Plants/trees play a very important role in our life. They fulfil our food, fodder fuel, timber, fibre and medicinal needs. Plants/trees are helpful in mitigation of environmental pollution.They are the source of oxygen and sink of carbon dioxide Trees such as Tamarind (Tamarindus indicus) Ashok (Polyalthia longifolia) and Neem (Azadirachta indica) are very useful in control of noise pollution. Plants/trees are also helpful in restoration of degraded lands. Furthermore, plants are useful in removal of heavy metals from the contaminated sites. Trees are helpful in the maintenance of ground water level.

Without them, land animals couldn't live on this planet, our water cycle will be disrupted and oxygen production will be cut short. They are the main source of food so food will be scarce. in short life without plants will be very hard but again we can survive without it if we can developed as like those science-fiction aliens.
