Organisms and their Environment

Each environment an organism inhabits holds a different set of constraints for processes related to the survival, growth, and reproductive ability of a species. Different patterns of temperature, precipitation, seasonality, depth, salinity, pH, and dissolved oxygen among terrestrial and aquatic ecosystems are reflected in the different characteristics that an organism exhibits. These characteristics include the … Continue reading Organisms and their Environment

What is Ecology?

Ecology is the study of the relationship between organisms and their environment Ecology is the scientific study of the relationships between the processes behind an organism’s ability to survive, grow and reproduce, and the physical/chemical components (abiotic – temperature, moisture, oxygen concentration, light availability) and the biological/living components (biotic) of their environment. Stemming from the … Continue reading What is Ecology?
