Me out guys. i’m not sure about the answer.

The correct option would be option 3) organism 1 and 3 will be more closely related than organisms 2 and 4.

Explanation:

Depending on the physical characteristics only, we can see that the organisms shown in number 1 and in number 3 are similar o one another but not purely identical. This means that these organism are closely related to one another.

The organisms shown in option 2 and 4 are not very similar to one another depending on the physical characteristics. Hence, we can say that organisms shown in number 1 and number 3 are more closely related to one another s compared to the organism shown in option 2 and 4.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
