The answer is C. El Niño would cause changes in the genetic makeup of organisms.
Answer:
They can breed and produce offspring that can breed.
Explanation:
The options you were given are the following:
- They can breed and produce offspring that can breed.
- They are members of the same community.
- They live in the same ecosystem, community, and biome.
- They have similar physical characteristics.
A species can be defined as a group of similar organisms that can reproduce and produce offspring that can produce as well. This is why the first option is the correct one.
In ecology, the term <em>community </em>refers to a group of populations of two or more different species that inhabit the same area. More than one species can be found in a biome and ecosystem as well, which is why the second and third options are incorrect.
Some organisms can look very similar but belong to different species. This is why the fourth option is not correct, either.
