Transcript of The Amazon Rainforest

The Amazon Rainforest
Relationships in the Amazon Rainforest
Envioronmental Changes
Energy Pyramid
Based on the food pyramid
Symbiotic relationships
Symbiotic relationships are the connection that different animals have with each other. There are three different symbiotic relationships.

mutualism-both animals work together and both animals benefit.
commensalism-one animal benefits while the other doesn't gain or lose anything
parasitism- one animal benefits at the expense of another;the other animal suffers
The sloth with algae growing on its fur
A Predator & Prey relationships
One example of a predator prey relationship in the Amazon rainforest would be the relationship between the harpy eagle and the macaw. The harpy eagle hunts by watching for prey at a high perch. Once it sees potential preyit woops down and grabs the animal with its massive talons. It takes the food high into the trees to eat(heavier food is eaten n the ground). To defend itself from the harpy eagle, the macaw will either fly away, scratch at the eagle with its talons or maybe even bite it.
What Changes?
Some changes in a biome occur because f humans. This environmental change would be an example of this. The environmental change in this factor is deforestation. Deforestation is the cutting down of the trees in the rainforest.
Affects of Deforestation on the animals and their relationship
There are some good and bad affects of deforestation
Negative- With less trees, the howler monkey will have to live on the floor, making much them much easier prey to catch for the jaguars
Positive- When deforestation occurs, a lot of new animals will come down. The jaguar could shift interest towards the new prey, helping the howler monkey population grow.
Affects of Deforestation on the Ocelot
Deforestation will both help and hurt the ocelot, an endangered species.

Negative- The ocelot are already going extinct. Taking away its home would only hurt their numbers more.
Positive- Deforestation could encourage the ocelot to move to a new forest where they can raise their population. Once it gets used to a new habitat, if we humans could put them in similar habitats around the world, we could help raise the population of the ocelot.

The Rainforest Biome
A biome is a place where communities of animals and plants live together. Biomes have biotic (living) and abiotic (non-livng) factors. In the rainforest biome, there are many unique things you can find.
Abiotc factors in the Amazon rainforest are:

125-660 cms of rain
90% humidity
temperture- 20-34 degrees celsius
water (the Amazon River)
Biotic factors in the Amazon rainforest
plants- venus fly trap, cacao trees, the brazil nut tree and many other species of plant!
animals- bengal tiger, toucan, boa constrictor, and many others!
cacao plant
brazil nut tree
black agouti
howler monkey

emerald amazon tree boa
green anaconda

The Food Pyramid Explained
Food Web
The food pyramid is a chart to show the amount of energy that each animal receives through what it eats. When an animal eats another organism, it receives 10% of of the energy that the organism the animal ate had. For example, when a primary consumer, a macaw for example eats from a producer, the cacao plant, it receives 10% of the energy that the plant had. When an emerald amazon tree boa ( a secondary consumer) eats the macaw, it recieves 10% of the energy that the macaw held. The tree boa recieves 10% of the 10% that the cacao plant held. When the harpy eagle(tertiary consumer) eats the tree boa, it receives 10% of the energy that the tree boa had. lt in turn gets less energy than any of the animals before it. The higher up that you go on the food pyramid, the less energy that it carries.
Let me give you an example of a symbiotic relationship. This is an example of mutualism. These two organisms help each other survive. These organisms are the sloth and algae. Because the sloth moves so slowly, algae can grow easily on the sloth's fur. The algae in turn camouflages the sloth and hides it from predators. This is an example of mutualism because both of the animals benefit.
