A little room to wonder
Ecology
Ecology studies relationships between living things and their surroundings. It asks what changes when one part of a living system changes.
Which relationships would I miss if I studied only one organism?
An ecosystem includes the surroundings
An ecosystem brings together a community of organisms and the physical environment they interact with. It can be as large as a forest or as small as a pond. Water, light and temperature belong in the picture alongside living things; a list of species alone does not describe the whole system.
Biodiversity has several scales
Biodiversity includes variation in genes, the variety of species and the variety of ecosystems. Counting species answers one question, but it does not capture all three levels. Two places with similar species counts can still have different habitats and relationships, so be clear about what a comparison measures.
Observe without overstating
The mangrove photograph shows roots and water together. It can prompt questions about shelter and changing water conditions, but a photograph alone cannot establish every species or interaction present. Record what you observed, where and when it was observed, and which explanations still need checking. One visit is a snapshot, not a complete ecological survey.
Only if you feel like trying
Map relationships from a window
- Choose a view you can observe safely without entering a habitat, or use the photograph.
- Draw three living features or visible plant parts and two physical features. Mark uncertain identifications as unknown.
- Add arrows labelled “possible relationship” and choose one that would need evidence.
Optional observation or drawing. Stay on safe access routes; do not disturb wildlife, enter water or collect organisms.
Look at the sources.
