Excerpts and links may be used, provided that full and clear credit is given to Matrix Education and www.matrix.edu.au with appropriate and specific direction to the original content. The Theory of Evolution by Natural Selection can be used to explain periodic increases and decreases in populations and biodiversity. The distribution of fossils also supports the idea of continental drift, as fossils of some organisms are found on continents that now are very far apart and have different habitats. These are the ‘services’ a functioning ecosystem provides. © 2020 Matrix Education. Food webs show how a change in abundance of one species can lead to flow-on effects to other species. The following graph depicts the relationship between Lynx and Hare populations. During this module, you will look at specific examples of these relationships. Evidence of continental drift helps us understand how environments on different continents would have changed in the past. You will look at ecosystem dynamics, past ecosystems and the models that can be used to predict future ecosystems so that human impact on biodiversity can be minimised. As snow falls, air is trapped under the layers of snow. (b) The sudden loss of a population of a species. 5.04.1 Introduction. Other examples include the use of computer models or manipulative experiments to observe how organisms and ecosystems respond to predicted future changes.

The biodiversity of the Earth has constantly changed since life first appeared on the planet. This engaging and authentic depth study and excursion addresses the syllabus inquiry question “What effect can one species have on the other in a community”. Since mining is a highly destructive process, government bodies work with mining companies to implement a restoration plan once the mine is decommissioned. Global Ecosystem Dynamics Investigation (GEDI, pronounced / ˈ dʒ ɛ d aɪ /) is a NASA mission to measure how deforestation has contributed to atmospheric CO 2 concentrations. The way these factors interplay will directly impact how species survive within an ecosystem . A simple example is a food web that shows how change to one species leads to flow-on effects for other species as a result. (b) Distribution of the Glossopteris fern. Vegetation Dynamics.

For example, Dickson’s Thylacine was a small carnivorous marsupial. The discovery of two emu-like paintings in Arnhem Land provided evidence that humans co-existed with the megafauna bird Genyornis which became extinct over 40 000 years ago. An ecosystem is a community of living organisms (plants, animals, and microbes) existing in conjunction with the nonliving components of their environment (air, water, and mineral soil), interacting as a system.

This eventually results in an increase in lynx and the cycle starts again. This includes: The study of past ecosystems and understanding how they are changing now will enable scientists to predict future impacts on biodiversity. Keystone Species. Commensalism is the relationship between two organisms where one organism benefits while the other is unaffected. Estuaries are dynamic ecosystems that host some of the highest biodiversity and biological production in the world (Bianchi, 2007).At the land–ocean interface, estuaries receive large amounts of dissolved and particulate carbon (C), nitrogen (N), phosphorus (P), and silica from rivers. GLERL's focus on Lake Michigan has led to the establishment of the Long-Term Research (LTR) program. Our HSC experts will break down Ecosystem Dynamics and provide you with plenty of practice questions to ensure that you are always a few steps ahead. Module 4 allows us to apply basic knowledge of biology with studies of evolutionary biology and biodiversity to analyse how ecosystems have changed and will change over the course of history.

Inquiry question: What effect can one species have on the other species in a community? (a) When a large number of individuals of a species are killed. The Thylacine was thought to be hunting sheep and so was hunted to protect farms until eventually the species was wiped out. The modern-day prevalence of sclerophyll plants in Australia provides evidence that as Australia drifted North from Antarctica, its climate became warmer and drier.
