Water “Plants need water. Water is essential to all life on earth. No known organism can exist without water. Plants use water to carry moisture and nutrients from the roots to the leaves, and food from the leaves back down to the roots.” Source: http://www.dnr.state.md.us/forests/education/needs.html

Soil “Plants need soil. Water and minerals are taken from the soil through roots. Soil also provides support for the plant and an anchor for the roots to grow in. Decaying plants and animals leave behind minerals in the soil that are essential for future plant growth.” Source: http://www.dnr.state.md.us/forests/education/needs.html

Air “Plants must also have clean air. Green plants take in carbon dioxide from air and use it during photosynthesis to make food. Dirty, smoggy air blocks sunlight that plants must have.” Source: http://www.dnr.state.md.us/forests/education/needs.html

Light “Plants need sunlight in order to grow properly. They use light energy to change the materials - carbon dioxide and water into food substances (sugars). This process of food production is called photosynthesis. Only in light can a green plant make food.” Source: http://www.dnr.state.md.us/forests/education/needs.html
