Bulimba Creek Essay

Ecology and evolution are considered sister disciplines of the life sciences. Natural selection, life history, development, adaptation, populations, and inheritance are examples of concepts that thread equally into ecological and evolutionary theory. Fresh water ecosystems is a living community of interacting organisms and their physical environment and habitat. Freshwater ecosystems are a subset of Earth's aquatic ecosystems. Some of those aquatic ecosystems include lakes, ponds, rivers, streams, springs, and wetlands. Within an ecosystem the organisms are rarely distributed evenly and therefore it can be very difficult to count their numbers accurately. Scientists therefore need to adopt an appropriate sampling technique to achieve a realistic estimate of population numbers. This field study will focus on the ecosystems in Bulimba Creek. With the wide spread of variety of fauna and species found within the boundaries of Bulimba creek, it supports a …show more content…
Abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Indicator species is any of the living species that defines any trait or characteristics of the environment. Adaptation is another main key term used in ecology. Adaptation, also termed as an adaptive trait, is a trait with a current functional role in the life history of an organism that is sustained and evolved by natural selection. The categorization of biomes into zones based on their distribution or arrangement in a habitat as determined by environmental factors, altitude, latitude and temperature. Interrelationships the way in which each of two or more things is related to the other or others. Interrelationships can be linked to food webs and food chains where organisms find ways to provide
