Well, in this article we provide you with a detailed overview of Module 4: Ecosystem Dynamics to help you get ahead of your studies! (a) Identify which type of relationship exists between the two species based on the graph. 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. The biodiversity of the Earth has constantly changed since life first appeared on the planet. For example, water and light availability affects the distribution of plants. The key postulates that have guided science since the Enlightenment appear to be wholly inadequate to describe properly the development of ecosystems.

If you continue to use this site, you consent to our use of cookies. The hunting of the Thylacine by farmers caused a major decline and ultimately the extinction of the species. Scientists can use modelling to depict processes and systems of future impact. Since mining is a highly destructive process, government bodies work with mining companies to implement a restoration plan once the mine is decommissioned. A full-waveform LIDAR was attached to the International Space Station to provide the first global, high-resolution observations of forest vertical structure. For example, fossils of the now-extinct Glossopteris plant are found across all of the continents shown below. Covers a full summary of the year 11 Biology Ecosystem Module.

Image 1: The dark green areas highlight regions where the Gossopteris fossil was found in Gondwana.Image 2: Glossopteris fossil seed fern leaves in claystone. Fire use for Aboriginal land management lead to a higher prevalence of fire tolerant plant species and expansion of grasslands. Year 11 Biology - Ecosystem dynamics … (a) When a large number of individuals of a species are killed. In this module, you will examine some practices used to restore land that is degraded due to mining or agricultural practices. Well, let's put that knowledge to test with these 10 practice questions! This includes: The study of past ecosystems and understanding how they are changing now will enable scientists to predict future impacts on biodiversity. The way these factors interplay will directly impact how species survive within an ecosystem . This course is an introduction to ecology and ecosystem dynamics using a systems thinking lens.

Ice core drilling can be used to provide evidence about past climates. In the process of quantifying water flux and nutrient cycles at the small watershed scale it was imperative to measure vegetation composition, structure and productivity and their responses to forest management. Palaeontologists can use Aboriginal rock paintings as recordings of the species present in different regions tens of thousands of years ago. ROCK PLATFORM Location Long Reef Rock Platform, Collaroy Excursion Synopsis Since ecosystems change over time, paleontological and geological evidence can be used to provide insight into past ecosystems.

Radiometric dating can be used to determine the absolute age of a material such as rocks or fossils. It is the common ancestor of modern carnivorous marsupials such as the Tiger quoll, Tasmanian devil and Tasmanian tiger. Video footage of this animal is rare and a short clip of the last animal in captivity was recently rediscovered. 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. Through a case study on Mozambique's Gorongosa National Park, learners will explore how scientists study ecosystems, and investigate the complex array of factors that inform management efforts. The ratio of Carbon-14 to Carbon-12 continues to change consistently over time, so this ratio can be used to estimate the age of the sample. Remove the keystone and the whole arch fails. An example of a radioisotope is Carbon-14 which is taken up by organisms while they are alive and upon their death begins to decay to become Carbon-12. Creating habitats for plants and animals. You can find the answers at the bottom of the page. These mid-ocean ridges or spreading zones push continental plates apart.

Food webs show how a change in abundance of one species can lead to flow-on effects to other species. 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.

Species that eat grasses (such as kangaroo) became more common. Magma rising from the ocean floor pushes through the crust and eventually cools down forming new rocks. This increase in predators decreases the hare population, to the point that Lynx run out of food and decline. Other examples include the use of computer models or manipulative experiments to observe how organisms and ecosystems respond to predicted future changes.
