Biological Diversity التنوع (الأحيائى) البيولوجى Classification of living organisms تصنيف الكائنات الحية The organization of living things can be seen like a pyramid or tree with seven major levels or categories: 1. Kingdom مملكة 2. Phylum شعبة 3. Class طائفة 4. Order رتبة 5. Family عائلة 6. Genus جنس 7. Species نوع e.g. Chlorella vulgaris Chorella vulgaris
