The: Daintree Rain forest
Transcript of The: Daintree Rain forest
Hi, my name is Stacy. I'm 7 years old, and i'm here to tell you about the time I went to the tropical rain forest in Australia with my mom! It was a great experience and i'd LOVE to go back and visit another time. During the time I spent there, I learnt many things about it's ecosystem, about the living organisms living there, and other many things that I'd like to share with you!
Did you know that enough rainforests are being destroyed every minute to fill 50 football fields? I was surprised when my mother told me that these beautiful tropics were being destroyed, especially since they are an ecosystem to many animals, plants, insects, and other organisms. Speaking of which, I should probably tell you what biomes are ecosystems are if you didn't know already!
What do YOU know about Biomes & Ecosystems?
is a large area on the Earth's surface that is defined by the types of
that lives there.
includes all of the living plants and animals in a specific area.
They can be as small as a puddle or even as big as an ocean.
While my mom and I ventured out in the forest, there were mostly trees surrounding it.
There weren't many plants on the ground the trees block the majority of sunlight that the plants need to make food.
We found a beautiful river where we could cool off in from all the humidity in the forest.
You could even sit on the giant rocks that were present there!
I always wondered what would it be like if there were no abiotic and biotic factors. But then I realized without them, the forest wouldn't even exist!
I asked my mom one night during our trip at the forest, 'Mom, if there were no sunlight or animals, would this forest even exist?' and with that she replied to me saying 'No, stacy. If there were no sunlight, soil, water, or any other abiotic factor, there wouldn't be a forest.'
If you didn't know what abiotic and biotic factors are..well,
Abiotic factors are nonliving factors that affect living organisms. Like:
Without abiotic factors, there wouldn't be food for for those Herbivores & omnivores that feed off of plants. And, if those organisms die, the Carnivores wouldn't have any food to eat, meaning they would die aswell.
Biotic factors are living organisms that exist in the ecosystem
Some living things like trees and plants gives animals and other organisms food and shelter. If there weren't any, its affect would be that many of the groups of living things would cease to exist.
'Mother' I said, 'do you know if there are factors other than than biotic and abiotic factors that affect the population of species as a whole?' My mother replied, 'that's a good question dear. There are factors that affects the population of living things, which are density-dependant and density-independant.
'Density-dependant factors are those which affect the population more as the population number's rise. For example, if the number of monkeys in the rainforest increases, the less food will be available because there are so many of them that eat up alot of the natural resources.
Density-independant factors affect both small and large populations equally. Think of natural disasters that have happened, such as floods, earthquakes, volcanoes, and even man-made things like dams.
The good news is, however, if there are enough natural resources to go around, the population will stay consistent, and the monkeys will not die out.' she said.
In the forest, there were many unknown organisms that I werent sure of. So I took a picture of one of them.
When I showed it to her, at first she wasnt so sure what it was. But then she realized it was a Mangrove. Mangroves are 'producers' because they make their own food.
There are also other producers in the Daintree Rain forest, such as Algae, Moss, Idiot Fruit, Blue Quandons, and much more.
If there are producers, then there would also be organisms that can't make their own food. And, those organisms happen to be consumers. Consumers eat plants and other edible things unlike the consumers, who make food for themselves.
Some examples of consumers would be Spotted Cuscus, Sugar Glider, the Ulysses Butterfly, and more.
After splashing around in the Mossman river, I saw a frog and an insect close by. I watched them intently, wondering what would happen next as the frog stared-down the bug. The next thing, I saw the frog wrap his tongue around the insect's body and devour it.
This would be an example of predator and prey relationship where an organism eats another organism.
Woken up by the sound of my mother's voice, I took a glance at the area surrounding us. I soon discovered there was a forest fire a few miles away. Not thinking before myself, instinctively I knew, that she had awoken me so that we could run away, far from the fire. After we escaped, we had walked to a further distance away to watch the forest engulf itself in flames, while also far enough so we didn't have to worry about the fire coming towards us. I asked my mom, 'What's happening!? Why is there a fire in the forest?' 'The forest is going to burn down and start anew. And that's when I learned of
Secondary succession is one of the two types of ecological succession of plant life
It's a process started by an event (ex. forest fire) that reduces an already established ecosystem (ex. a forest, wheat field)
to a smaller population og species, and as such secondary succession occurs on preexisting soil.
There are many trees that are cut down because people need jobs and the wood can make a lot of money for lumbering companies. Unfortunately, they're contributing to it's decline.
Cutting down and killing things destroys the habitat of animals and take away their food supply. But we could also try to conserve it by replanting trees and plants while also enforcing laws against hunting endangered species.
I remembered seeing workers come over to my house's back yard to cut down trees last year. But I noticed a year after, those same trees never grew back. Since football fields are made out of several forests, I guess there will be no more.
