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.
Actually, thereâs a very good â and scientific â reason for farmers to plant different crops in a field from year to year. Itâs a process known as crop rotation, and itâs actually been around a long, long time. Crop rotation refers to the practice of growing different types of crops (or none at all) in the same area over a sequence of seasons. Historians believe farmers in the Middle East practiced crop rotation as early as 6,000 B.C., although they didn't fully understand the science behind it.
