What is ecology primarily concerned with?

Ecology is primarily focused on the relationships between living organisms, including plants and animals, and their physical environment. It encompasses a broad range of interactions, examining how different species cohabit ecosystems, how they compete for resources, and how they respond to environmental changes. This includes studying food chains, habitats, and the impact of human activities on these relationships.

The concept of ecology goes beyond just one group of organisms, such as insects, hence the emphasis is on the broader connections among various life forms. The interactions explored can include predator-prey dynamics, symbiotic relationships, and the influence of abiotic factors such as climate and soil conditions. By understanding these complex networks, ecologists can better predict the consequences of environmental changes and human interventions on biodiversity and ecosystem health.

The other options focus on narrower aspects of biological science. For instance, the interaction of insects alone does not capture the complexity of ecological relationships. Similarly, the study of chemical interactions in plants or the management of animal populations falls within specific branches of biology or wildlife management but does not encompass the entire field of ecology.
