1 grade: 1 species.

Climbing level 2: 2 kinds

Climb the third level: 1+2=3 kinds (the previous step starts from 1 or the second level).

Climbing Level 4: 2+3=5 kinds (the previous step starts from Level 2 or Level 3).

Grade 5: 3+5=8 kinds.

Grade 6: 5+8= 13 species.

Grade 7: 8+ 13=2 1 species.

Grade 8: 13+2 1=34 species.

Climbing level 9: 2 1+34=55 kinds.

Grade 10: 34+55=89 kinds.

So the answer is: 89.

Train of thought; Recursing from 1 level, feet fall to 1 level only 1 way from the ground; There are two possibilities for the second level, from the ground to the first level or directly from the first level; Upgrade to the third level, divided into two categories, either starting from 1 level or starting from the second level, so the method number is the sum of the first two levels; By analogy, the number of methods in each subsequent level is the sum of the number of methods in the first two levels; Until 10 level, find the number of methods at each level, and then get the solution.
