🌿 Limiting Factors & Photosynthesis: Boosting Crop Yields 🌿

Discover how farmers use glasshouses and polytunnels to control limiting factors and increase the rate of photosynthesis — leading to higher crop yields and better food production.

In this video, we explain how adjusting key factors such as temperature, carbon dioxide concentration, and light intensity can optimise plant growth. Learn how controlled environments help produce more glucose, reduce pest damage, and support sustainable agriculture.

🔍 Topics covered:

The science behind photosynthesis and enzyme activity

How glasshouses regulate temperature, CO₂, and light

The benefits of polytunnels for weather protection and pest control

The balance between cost and profit in modern farming

Perfect for GCSE Biology revision or anyone interested in agricultural science! 🌱
