Final answer:
Plants provide humans with oxygen and food.
Step-by-step explanation:
The two most important things that human beings receive from plants are oxygen and food. Plants produce oxygen through the process of photosynthesis, where they convert carbon dioxide into oxygen. Oxygen is essential for human survival as it is needed for cellular respiration. Additionally, plants provide us with food in the form of fruits, vegetables, grains, and nuts. These plant-based foods are rich in nutrients, vitamins, and minerals that are necessary for our overall health and wellbeing.
