The ice can be crushed to release the trapped gasses, which are then separated out by a gas chromatograph. Ecosystem Dynamics. A recent extinction event is the Thylacine (Tasmanian tiger) which was a carnivorous marsupial closely related to the Tasmanian devil. Biology Depth Study Program trailer. Magma rising from the ocean floor pushes through the crust and eventually cools down forming new rocks. Select a different course. Creating habitats for plants and animals. Competitive Exclusion Principle. Ice cores taken from polar ice caps and glaciers can reveal information about past climates. Creating habitats for plants and animals. You can find the answers at the bottom of the page. These are the ‘services’ a functioning ecosystem provides. Working on conservation initiatives in partnership with local communities. by Alex Gao. Want to get ahead in Biology? Extinction of species can occur due to biotic or abiotic factors, natural phenomena such as climate shifts or human activities such as hunting. The biodiversity of the Earth has constantly changed since life first appeared on the planet. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystem dynamics. Cells as the basis of life. The Theory of Evolution by Natural Selection can be used to explain periodic increases and decreases in populations and biodiversity. Since mining is a highly destructive process, government bodies work with mining companies to implement a restoration plan once the mine is decommissioned. Build your confidence in Year 11 Biology with Matrix! Covers a full summary of the year 11 Biology Ecosystem Module. Site video and explanation of the investigation process and equipment. 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. (b) Explain the pattern of abundance seen in the Lynx and the Hare populations. Which of the following sampling methods can be used to determine the abundance of sessile populations? 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. 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. All Rights Reserved. Module 4: Ecosystem Dynamics is the final module in the Year 11 Biology course and effectively wraps up most, if not all the concepts we’ve explored in the previous 3 modules! ROCK PLATFORM Location Long Reef Rock Platform, Collaroy Excursion Synopsis (a) Identify which type of relationship exists between the two species based on the graph. Macmillan Education Biology. Biology Year 11 - Ecosystem Dynamics . The Thylacine was thought to be hunting sheep and so was hunted to protect farms until eventually the species was wiped out. Abiotic & biotic relationships in this ecosystem Analysing & Concluding Saline conditions Tidal movement Ecological niches. The following graph depicts the relationship between Lynx and Hare populations. We have assembled the following 10 Ecosystem Dynamics practice questions to help you prepare! Keystone Species. Ecosystem Outputs. 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. Scientists can extract this material from cores of ice which provide a chronological record of the Earth’s past climate. Our HSC experts will break down Ecosystem Dynamics and provide you with plenty of practice questions to ensure that you … Food webs show how a change in abundance of one species can lead to flow-on effects to other species.
