📖 Nature's Neighbourhood
Imagine a pond. It's not just water — it's a whole world! Fish swim, frogs croak, plants grow, insects buzz, bacteria decompose dead stuff. They all depend on each other and on the physical environment (water, temperature, light). This web of interactions is an ECOSYSTEM. Every living thing has a role to play, and if one piece changes, the whole system feels it!
What is a habitat?: The place where an organism lives — the specific part of the environment that provides everything the organism needs to survive.
