biodiversity class 12

Bees are crucial for biodiversity. They pollinate a vast number of plants. When bees transfer pollen from one flower to another, it enables plants to reproduce. This leads to more plant species thriving, which in turn provides food and shelter for many other organisms.

One success story is the Convention on International Trade in Endangered Species (CITES). It has been successful in reducing illegal trade of endangered animals and plants. For example, it has helped in protecting elephants from the ivory trade by strictly regulating the international trade of elephant products.

There are several factors. Nepal has established many protected areas which safeguard various habitats and species. Also, the local communities' active participation plays a crucial role. They have traditional knowledge about the local ecosystems and are involved in conservation efforts like sustainable forest management.

One key achievement is the increase in the population of some endangered species. For example, the number of Bengal tigers has shown an upward trend. This is due to effective anti - poaching measures.

Captive breeding success stories are vital for biodiversity conservation in multiple ways. Firstly, they increase the population size of endangered species. Take the black - footed ferret as an example. By breeding them in captivity, we can release more individuals into the wild, which helps to re - establish their populations. Secondly, captive breeding programs often involve research. This research can help us understand the species better, like their breeding habits and dietary needs. This knowledge can then be used to improve their conservation in the wild. For instance, we can create more suitable habitats based on what we learn from captive breeding. Also, successful captive breeding can raise public awareness about endangered species and the importance of conservation, which can lead to more support for biodiversity protection in general.

The Convention on Migratory Species has also had success regarding marine life. It has helped protect migratory marine species such as whales and sea turtles. For example, it has coordinated international efforts to reduce the by - catch of sea turtles in fishing nets. By raising awareness and implementing conservation measures across different countries, the survival chances of these migratory species have increased.

Class system and class culture are important components of the school education system, which have an important impact on the growth and development of students. The class system referred to the rules, regulations, and management measures that the class as a whole had to abide by in the school education system. These rules and regulations and management measures included curriculum arrangements, discipline management, student management, and so on. Under normal circumstances, the class system would be formulated according to the school's regulations and policies, and it would be widely participated and discussed by the students in the class. Class culture was the sum of the atmosphere, spiritual outlook, and cultural characteristics between the students and teachers in the class. Class culture usually included a positive attitude, a spirit of unity and cooperation, and the habits and behavior of respecting teachers and classmates. Class culture could be formed and reflected through the inheritance and implementation of the class system, through the students 'self-shaping and active participation. The class system and class culture were related and mutually reinforcing. The formulation and implementation of the class system helps to shape the class culture, and the class culture helps to promote the implementation of the class system. At the same time, the class culture would also affect the construction and implementation of the class system. Therefore, in the school education system, we should pay attention to the formulation and implementation of the class system, and also pay attention to the construction and development of class culture to provide a good environment and atmosphere for students 'learning and development.

Fan Xian's class was the homeroom teacher's.

Fan Xian's class was the homeroom teacher's. Fan Xian was compared to the class teacher, fighting wits and courage with the students. This scene reminded people of the interactions with the class teacher in school. Although the search results did not explain in detail what Fan Xian's class smell was, it could be inferred that Fan Xian's class smell was similar to the sense of responsibility, authority, and management ability of a class teacher.

There was no definite answer to the division of the martial arts realm between third-class, second-class, first-class, and super-class. The search results mentioned different people's personal views on the division of Wuxia realms, but did not provide a generally recognized division standard. Therefore, based on the information provided, it was impossible to give an accurate answer.
