Ecological means relating to the relationships between living things and their environment. When scientists study how owls hunt mice in a forest, how coral reefs support thousands of fish species, or how bees pollinate flowers, they're studying ecological connections.

The word comes from ecology, the science of understanding how organisms interact with each other and their surroundings. An ecologist might investigate why certain plants grow better near rivers, or how removing wolves from an area affects the deer population, which then affects the plants the deer eat, which then affects the insects living on those plants. Everything connects.

You'll often hear about ecological balance, which describes how healthy ecosystems maintain themselves naturally. When people talk about ecological damage or an ecological disaster, they mean harm to these natural connections: a polluted river that kills fish, or cleared forests that leave animals without homes.

The word helps us think about nature as a web of relationships rather than just individual plants and animals.
