The Daintree rainforest, a region located in tropical far north Queensland, is the biggest continuous rainforest in Australia (refer to figure 1 for location on map). Around 1,200 square kilometres in size, the Daintree rainforest is home to fast flowing streams and waterfalls to mountain ranges and dense rainforests, along with a variety of landscapes and a range of different and native flora and fauna. The forest is along the north coastline of the Daintree river, with the tropical rainforest growing right until the edge of the sea. The forest has a high annual rainfall of around 2000mm per year with 60% of the rainfall occurring in the wet seasons between December to March.
Biotic and Abiotic factors have major roles …show more content…
This can occur due to chemicals being taken up faster than it should/can be use, or due to the chemical not being able to be broken down for use by the organism (chemical can’t be metabolised). Bioaccumulation is harmless if the compound that was accumulated is not harmful. Although, compounds such as mercury, can accumulate into living tissues and therefore be dangerous to health. Chemical pollutants that are bioaccumulated come from many sources like pesticides. Pesticides are a contaminant that bioaccumulates in organisms. When an animal consumes 10 pounds of food, approximately one pound of that food can become body mass. This increases toxin substance amounts nearly 10 times for the food chain/web. This also provides threats to predators and human that eat meat and fish because some toxins are dangerous to health. The bioaccumulated substances are stored in fat, but are released in the bloodstream when the animal uses the fat for energy, which can harm organs and systems in the animal’s body. If the substances harm important species in a rainforest or an ecosystem, then this will affect the producers and the predators because there will be a higher population of producers’ due to the animal not consuming it and the predators will lose a crucial food source and will cause other animal populations to decrease because it has become the main food source. Bioaccumulation can also lead to lower population or extinction of numerous species because the accumulation of toxins will not only directly affect one animal, but will also affect the offspring because the dangerous substances are also released through the breast tissue which produces the milk for the
