The Daintree Tropical Rain Forest can be found at the North-East Coast of Queensland, Australia. It covers about 2,600 square kilometers of land. Many different kinds of plants and animals can be found here. Many animals need to survive here, with limited food and predators wanting to hunt and eat other animals.
Abiotic Factors
- Intense rainfall
- flash flooding
- little light reaches the ground
- rain all year round
- moist soil
Biotic Factors

- Bennett's Tree Kangaroo
- Musky Rat Kangaroo
- Masked White Tail Rat
- Byod's Rainforest Dragon
- Possum
- Green Tree Frog (shown on the left)
- Salt Water Crocodiles
Density independent Limiting factors
fklopplpijjuhhbjhbjhgb
- Tourism- 400,000 people visit the rainforest every year
- Development- the process of cutting down trees to make attractions
Density dependent factors
- Predation- cassowary eats some reptiles
- Parasitism- monkeys have ticks that they eat
- Competition- plants compete for sunlight and animals compete for food
endangered species

The Cassowary Bird (Casuarius casuarius) is one of the main endangered species in the Daintree Rainforest. In September 2013, there were around 1,500 to 2,000 left in the world. They are endangered because:
- Loss of habitat from cleaning of trees
- Vehicle traffic
- Some have been illegally killed by people
Keystone species
- Cassowaries; icon of tourism play an integral part on the ecosystem
Primary succession
- Flooding is quite often, caused the top soil to strip
secondary succession
- Cut down large areas for crops, later becomes infertile, once the farmers move after 100's of years tree grow back
biogeochemical cycle for the biome

When a plant dies, it gives off nitrogen into the soil and water, or when herbivores, consumers that only eat plants die or give off nitrogen compounds. So, this releases nitrogen which goes through nitrogen fixation .The chemical processes by which nitrogen is transformed into organic compounds. This is then absorbed through the plants and eaten by herbivores and carnivores. When these organisms die or give off waste they are then then broken down and converted into ammonia through ammonification(converts ammonia into nitrate) When plants absorb this, bacteria breaks it back down into nitrates through nitrification. Nitrification is when ammonia transforms into nitrates. Through denitrification (process of nitrate reduction), the nitrates are brought back into the environment as nitrogen gas, this completes the nitrogen cycle.
human impact on the biome
Logging, farming and mining are all human impacts on the Daintree rainforest. All of the human impacts hurt the rainforest because people have to remove trees and dig up the ground. If humans keep on digging up trees and the soil there won't be as many trees there that are there today. When the trees get dug up it takes them hundreds of years to grow back, which means less shelter for animals to hide at protect their selves at for a long period of time.

Symbiotic Relationshiips
Commensalism:
- Staghorn Fern to Tree Hosts-benefits from the relationship with its tree host by using the tree to get higher to get more sunlight for photosynthesis
Parasitism:
- Strangler Fig to Tree Host- The Strangler Fig benefits from the relationship it has with the host tree which becomes decreased from this event because it raps around it, cutting of the light from the three therefore photosynthesis is unable to continue.
Primary Producers
- Mangroves, Idiot fruit, Blue quandons, Burrawarig palm, Wild ginger, Algae, Moss, Rattan, Comet Orchid, Benga Bamboo, and the Kopak Tree.
Consumers
- Cassowary, Insects, Ulysses, Butterfly, Whichetty grub, Spotted cuscus, Sugar glider, Goanna, Azure Kingfisher, and Feral Pigs
Food Web
Predator/prey
Predator is an organism which eats other organisms; which are prey.
- Cassowarys eat reptiles
- Crocodiles eat platypuses
conclusion
In conclusion, there are many important things about animals in the Daintree Rainforest. Symbiotic relationships, biotic and abiotic factors, density dependent and independent factors, producers and consumers in the rain forest, food webs, energy pyramids, and many other things. Rainforests are the homes of half of all the animals in the world. We came up with some predictions for the Daintree rainforest in a few years. this is what we predict:
- Cassowaries may die off in a few years
- Parts of the forest might be gone due to deforestation
- Natural disasters could cause many plants and animals to die
We hope our website helped you a lot ☺ Thanks!
