Question

And how many map squares did we survive more than 29 plant species

Answer 1

Hello your question is incomplete attached Below is the missing histogram

answer: 10 map squares

Explanation:

There are 10 map squares that did survive more than 29 pant species because from the given diagram we can see that the plant species above 29 are spotted in 4 map squares ( i.e. from spot 30 to 39 ) and 6 map squares ( i.e. from 30 to 49 )

hence the total number of map squares = 4 + 6 = 10 map squares
