Sagot :
Answer:
1.Amazonia
~Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
2.The tundra
~The tundra is the biome with the least biodiversity.
3.The formula is:
~Step one: Calculate N(N-1) to find value A. N(N-1) = 202(202-1) = 202(201) = 40602.
Step two: Calculate n(n-1) for each species.
Step three: Add these numbers together to find value B.
Step four: Divide value A by value B. 40602÷ 6884 = 5.898. Index of Diversity,d = 5.90.
I cant answer number 3,but I will give you the formula to how to solve your question.
