Plants and photosynthesis. Animals eat food to get their energy. But green plants don't. Instead they make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise. These are the things that plants need for photosynthesis: carbon dioxide.water. light.lants and photosynthesis. Animals eat food to get their energy.

Crop Rotation. Definition - What does Crop Rotation mean? Crop rotation is the systematic planting of different crops in a particular order over several years in the same growing space. This process helps maintain nutrients in the soil, reduce soil erosion, and prevents plant diseases and pests.
R otation is when a planet or moon turns all the way around or spins on its axis one time. The axis of rotation is an imaginary line going from the north pole to the south pole. When a planet or moon travels once around an object this is considered a revolution.On Earth, a rotation is pretty short-it happens once a day!It is the rotation that makes the sun appear to come up in the morning and set at night. On Earth, a revolution is quite a bit longer-one year!hen a planet or moon travels once around an object this is considered a revolution. On Earth, a rotation is pretty short-it happens once a day!
