The correct answer is A. Ecology.
Ecology is the branch of biology that studies the relationships between organisms and their environment. It includes the study of the distribution of organisms, their interactions with each
other and with the environment, and the effects of these interactions on the populations of organisms.Taxonomy is the science of classifying organisms. It involves identifying and naming organisms, and grouping them into related groups based on their shared characteristics.
Evolution is the process by which species change over time. It is a gradual process that can take millions of years. Evolution is driven by natural selection, which is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce.
Genetics is the study of genes and heredity. It involves the study of how genes are passed down from parents to offspring, and how they affect the physical characteristics of organisms.
Here is a table that summarizes the key differences between ecology, taxonomy, evolution, and genetics:
| Field of Biology | Focus |
| — | — |
| Ecology | The study of the relationships between organisms and their environment |
| Taxonomy | The science of classifying organisms |
| Evolution | The process by which species change over time |
| Genetics | The study of genes and heredity |
