The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
The difference between them is that an ecosystem is a community of organisms and their environment. And a biosphere is all the living organisms.
