📘 Details & Usage

📖 Root Explanation

'Eco-' from Greek 'oikos' meaning 'house' or 'habitat', and '-system' meaning an organized whole.

💡 Mnemonic

Think of ECO as ECOlogy (home of life) and SYSTEM as interconnected parts.

📖 Example

In the forest ecosystem, trees provide homes and food for animals, while animals help spread seeds for new trees to grow. 🔊 Within a forest ecological community, trees act as both shelter and a food source for wildlife, and in return, animals assist in dispersing seeds to promote the growth of new trees.
