ecology

Each morning , Maria walks to the small park near her flat to watch the plants and birds . She has been studying ecology at university , so she notices how different species help and depend on each other . Although the park is not large , a variety of insects and flowers can be seen , and she writes these observations in her notebook . If she had more free time , she would join the conservation group that cleans the pond at weekends . Her teacher once said that learning about ecology can change the way you understand everyday places , and that thought stays with her as she walks home .
