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.
Crop Rotation and Fallow Land. The core philosophy behind crop rotation is to never allow crops to completely deplete the soil of any one nutrient. Alternating different plants helps keep that balance intact. Letting a field lie fallow, free from any cultivated crop, is often part of a good crop rotation program. By remaining unsown, the ground rests and fertility can be restored. Crop rotation is all the more important in fields where the soil is prone to depletion or where demanding crops have been grown.
