Some factors are visible, while others cannot be seen. In the school test example, if the pupils are used to regular testing, then the ecological validity is high because the testing process is unlikely to affect behavior. 1. Environmental factors entail everything that changes the environment. Ecology is the study of intricate interactions among living and nonliving things and their environment, and the balance of ecology helps determine the very health and well-being of our planet. ). In this perspective, we suggest that adaptation may influence the effect size of treatments in ecological field experiments and alter our predictions of future dynamics in ecological systems. We can broadly group factors influencing ecosystems into: biotic factors - living factors affecting an organism, such as food, composting or disease, and abiotic factors , non-living factors.
