Because with out plants you wont have oxygen
No. Green plants were on the planet, long before there were people. Green plants need carbon dioxide, water, sunlight, soil, and seeds to live. They do not need people.
because all the people need it and in it grow the plants
Why do people breathe ? Plants need oxygen too .
need food and water to live just like us people do
No, because man and animals produce carbon dioxide and plants needs carbon dioxide.
Without plants we would struggle to survive. Plants release oxygen into the atmosphere and this is important for people because we need oxygen. Plants also provide food for people. Plants are not only directly used for food by people but the animals we eat for meat are raise on plants or plant products.
One relationship is plants emit oxygen which animals need to survive; animals then emit carbon dioxide which plants need to survive.
Plants can make sugar which is their source of calories but like people, they also need their multivitamins. They get these from their soil which is supposed to be rich in minerals but sometimes, the soil has been used up and the plants can;'t get enough to fix this, people give plants fertilizers to provide nitrogen, phosphorous, and other things the plants need. Its like multivitamins for plants.

Geologic time and evolution.
Plants need water in order to perform photosynthesis. Photosynthesis = Water + Carbondioxide+Light -----> Oxygen + Carbohydrate Plants need to breakdown H2O molcules in order to make ATP and carry out cellular funtions. Plants need water for similar reasons that people do....except that people don't carry out photosynthesis.
the dead cells in the soil help the plants grow and plants give you oxygen which humans need
