(20 14? Tai 'an) Analyze the data and answer the questions: Data 1: Mount Tai is located in a warm temperate climate zone and in the North China Plain, with a relative height difference of over 1 500m. (1) Biodiversity of biological species refers to the richness of biological clocks (including animals, plants and microorganisms) in a certain area. For example, there are about 1.7 million confirmed species in human beings, 1.244 known species in China, and 3,000 angiosperms, that is, biodiversity and its changes at the species level.

(2) Species is the most basic unit of biological taxonomy.

(3) The evolution of vertebrates: ancient fish → ancient amphibians → ancient reptiles → ancient birds and mammals. The picture shows the evolutionary tree of some organisms in Mount Tai. ① The biological groups represented are amphibians.

(4) Biota ② Mammals have the characteristics of viviparous and lactation. Most animal embryos develop in the mother's body, get nutrients from the mother through the placenta, then discharge waste from it, and then produce from the mother after maturity.

(5) Biological group ③ Reptiles are real terrestrial vertebrates, and the dry land climate is suitable for their growth. Its surface structure to prevent water loss is horny scales or nails.

(6) The most effective measure to protect biodiversity is to establish nature reserves, which means to divide a certain area of land or water, including protected objects, for protection and management, also called in-situ protection; Analysis data 2: The most effective measures to protect the rare animal and plant resources and biodiversity of Mount Tai are to establish nature reserves, protect precious genetic resources, and establish endangered species germplasm banks.

So the answer is: (1) biological species; (2) species; (3) Amphibians; (4) placenta; (5) horny scales or nails; (6) establishing nature reserves; Germplasm bank
