The omission in the Convention on Biological Diversity that limits its effectiveness is:
A. It does not include bacteria, fungi, or protists.
Explanation:
1. The Convention on Biological Diversity primarily focuses on higher-order organisms such as plants and animals, but it does not explicitly include microorganisms like bacteria, fungi, or protists in its protection and conservation efforts.
2. This omission is significant because microorganisms play crucial roles in ecosystems, such as nutrient cycling, decomposition, and symbiotic relationships with other organisms.
3. By not including microorganisms in the Convention, it overlooks a vital aspect of biodiversity, which can impact the overall health and functioning of ecosystems.
Therefore, the exclusion of bacteria, fungi, and protists from the Convention on Biological Diversity hinders its ability to comprehensively address and protect the full spectrum of biodiversity in ecosystems.
