It's when your kidneys no longer have control over the excretion of wastes nor the volume of your blood (this is the extreme end of the scale, though you can have smaller scale kidney failure/dry kidney). This is a potentially very dangerous condition and, if necessary, patients may need to go on renal dialysis for it.
Plants are producers. Producers are living things that can make their own food using air, light, soil, and water. Plants use a process called photosynthesis to make food. Only plants can produce their own food.
Just like you, plants need food to grow! But what is plant food, and how do plants get it? Plants turn water and air into food. Water from the ground is sucked up by the roots. Carbon dioxide from the air is breathed in by the leaves. Energy from the sun is collected by the leaves. The energy is used to turn the water and carbon dioxide into food. The waste from making plant food is oxygen. Animals, humans included, need oxygen to survive. So, this process is very important for plants AND animals. This amazing process, of using the sun's energy to make food, is called photosynthesis. Did you enjoy learning about plant food?
