(c) The sudden loss of an entire species. In order to understand how our current ecosystems function and how they are changing, it is helpful to examine evidence of changes that occurred in these systems in the past. Ecosystem Dynamics. The lynx population increases when the hare population is abundant as there is more food to sustain the lynx population. (a) When a large number of individuals of a species are killed.

Species that eat grasses (such as kangaroo) became more common. Which of the following can be regarded as evidence that Australia was once part of Gondwanaland? The Lynx (predator) population increases when the Hare (prey) population is abundant as there is more food to sustain the Lynx population. This is the way living organisms interact within an ecosystem. |. Partnerships with local communities and organisations. Well, let's put that knowledge to test with these 10 practice questions!

Australian Sclerophyll plants, Eucalyptus, Banksia and Acacia. analyses ecosystem dynamics and the interrelationships of organisms within the ecosystem BIO11-11 Content Focus The Earth’s biodiversit y has increased since life first appeared on the planet. ecology The study of how living things are related each other and to their natural environment. While fossils indicate there were widespread rainforests across Australia in the past, the continent is now populated with sclerophyll plants such as Eucalyptus that have small leaves and a thick waxy cuticle as an adaptation for dry climates. Funding Availability: $53,000 per year for up to three years. Isotopes can be identified by Isotope Ratio Mass Spectrometry. Well, in this article we provide you with a detailed overview of Module 4: Ecosystem Dynamics to help you get ahead of your studies! With reference to a named organism, describe a recent extinction event. The biodiversity of the Earth has constantly changed since life first appeared on the planet. Ice cores taken from polar ice caps and glaciers can reveal information about past climates. © 2020 Matrix Education. Oops! The team member will also provide field assistance in assessments of ecosystem dynamics as needed. Get ahead these holidays with our Holiday Courses. The way these factors interplay will directly impact how species survive within an ecosystem . Two species competing for the exact same limited resource cannot stably coexist. 1970, Siccama et al. 5.04.1 Introduction. Year 11 Biology - Ecosystem dynamics with a depth study. Year 11 Biology Ecosystem Dynamics Programs can be used as stimulus or as practical investigation for the new Depth Study component and will contribute to 5 of the 15 required hours for a Depth Study. Evidence of continental drift helps us understand how environments on different continents would have changed in the past. The hunting of the Thylacine by farmers caused a major decline and ultimately the extinction of the species. Scientific knowledge gained from the fossil record and geological evidence enables scientists to study the complex relationships between biotic and abiotic factors. For example, water and light availability affects the distribution of plants. This includes: An example of such a restoration practice includes the Westside Mine in Lake Macquarie, New South Wales that was successfully restored post-mining in 2012. 1. The team member will contribute to research products to meet milestones and project objectives and provide services in support of research directed under GEMMD’s Sustainable and Healthy Communities Research Team.

Since mining is a highly destructive process, government bodies work with mining companies to implement a restoration plan once the mine has been decommissioned. 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. The modern-day prevalence of sclerophyll plants in Australia provides evidence that as Australia drifted North from Antarctica, its climate became warmer and drier. Video footage of this animal is rare and a short clip of the last animal in captivity was recently rediscovered. Which of the following sampling methods can be used to determine the abundance of sessile populations? Oops! The ice can be crushed to release the trapped gasses, which are then separated out by a gas chromatograph. In this article, we will break down the various topics you will study in Year 11 Module 4: Ecosystem Dynamics to help you get ahead and ace Biology. Want to get ahead in Biology? This eventually results in an increase in the Hare population and the cycle starts again. The interaction between the Lynx and the Hare shows that predation affects the population of both prey and the predator. Select a different module. We have assembled the following 10 Ecosystem Dynamics practice questions to help you prepare! Monitoring and controlling unwanted plants and feral animals. © Matrix Education and www.matrix.edu.au, 2020. Palaeontologists can use Aboriginal rock paintings as recordings of the species present in different regions tens of thousands of years ago. It is the common ancestor of modern carnivorous marsupials such as the Tiger quoll, Tasmanian devil and Tasmanian tiger. Join 75,893 students who already have a head start. Unauthorised use and/or duplication of this material without express and written permission from this site’s author and/or owner is strictly prohibited. Ecosystem Dynamics. (b) Explain the pattern of abundance seen in the Lynx and the Hare populations. Creating habitats for plants and animals. Examples include Aboriginal rock paintings, rock structure and formation and ice core drilling. A recent extinction event is the Thylacine (Tasmanian tiger) which was a carnivorous marsupial closely related to the Tasmanian devil.
