Limiting Factors: Swift Parrots

What are the limiting factors influencing Swift Parrots?
Have a scan through these sites and consider the questions below:

BirdLife Australia Swift Parrot Profile > Swift Parrot Fact file


Learn a little bit about Swift Parrots here  > ABC Catalyst short video

Q1. What are the density dependent factors that might be limiting the Swift Parrot population?
A density dependent factor is one that limits how members of a population live, due to the number of memberswithin that population

Q2. What are the density independent factors that might be limiting Swift Parrot population?
A density independent limiting factor  is one that limits how members of a population live – but is caused by a factor outside of population numbers alone 

Q3. What are some of the actions Scientitsts are taking to manage Swift Parrot population?

Chemistry in the Ecosystem

What will we be learning in the Chemistry unit? -Understanding atomic structure and the periodic table in (more) depth -Relating this to our understanding of soil and plant nutrition -Ions, anions and chemical bonding & how this impacts how plants take up nutrients -Elemental classification: metals, non-metals and metalloids -Chemical reactions: Photosynthesis and Respiration -pH. What it means and how it impacts plant growth. Let's start with refreshing you on the basics: Here are the links you'll need for the worksheet: 1. Scale of the Universe 2.    Khan Academy: Atoms Your Plant Nutrient Poster 1. Select one of the 17 essential plant nutrients Hydrogen Boron Carbon Nitrogen Oxygen Magnesium Phosphorus Sulfur Chlorine Potassium Calcium Manganese Iron Nickel Zinc Copper Molydendum 2. Make a small, A5 poster which clearly states: a) The elements name, symbol, atomic mass and electron shells b) A diagram of the atomic structure ...

Light & Plant Growth

Image
Light is obviously a limiting factor on photosynthesis: without it plants cannot take up carbon dioxide to form energy.   The three main attributes of light that concern plants are 1. The Quality: Including wavelength (colour)  2. The Quantity: How much exposure they receive (intensity) 3.The Duration: How long each period of light exposure goes for Activity 1: Photosynthesis and light availability   Watch the video below and see how availability of light (winter vs summer) limits the photosynthetic activity of plants (darker shades of green). In turn, reflect on how this must impact the overall food web and ecosystem of an area.  ACTIVITY 2: PLANT GROWTH AND LIGHT Watch this video The Effect of Light on Plant Growth . Dot point list (in your book) a quick summary of some of the ways that light impacts plant growth ACTIVITY 3: PHOTOSYNTHESIS AND WAVELENGTH Plant Growth and Wavelength Virtual Lab (requires Flash) What to Do: 1.  Run the simulator using ...
