Analyse the human impacts affecting the nature and rate of change of two ecosystems at risk. All ecosystems are placed under levels of stress that must be withstood or overcome in the form of evolution in order to adapt and survive. These attributes determine the resilience and vulnerability of each and every ecosystem. These forms of stress fall under two categories; natural and human induced. In regards to natural stress‚ the term gradual is used as it happens at a slower rate and lesser magnitude

The small city of Cairns may not be well-known but its claim to fame is that it is the doorstep to visiting The Great Barrier Reef.

Introduce this section with the food chain discussion card called ‘Under the sea’. Food chains are a flow of energy Food webs exist in a delicate balance. If one animal’s source of food disappears‚ perhaps from a natural cause such as a drought or a killer disease‚ many other animals in the food chain are affected.

called food. Food contains energy. The food (or energy) can be transferred from one organism to the other through food chains. The starting point of a food chain is a category of organisms called producers. Producers are‚ in fact‚ plants. So‚ we can say that all the food chains begin with a green plant (or grass) which is the original source of all food. Let us take an example to understand the meaning of food chain. Suppose there is a field having a lot of green plants (or producers of food). Now
