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.
