The Tropical Rainforest

Abiotic Factors

•warm/wet climates
•average 20-34 degrees Celsius
•warm air holds water vapor
•humidity: 77-88%

•annual rainfall 200 cM
•lots of sunlight

Biotic Factors

•avocado, coffee bean, bananas, lemon, orange, pineapple plants/trees
•ferns, bamboo, rubber trees, orchids, shrubs, moss and grass

•Bugs/animals: colobus monkey, sloth, bats, hummingbirds, bees/wasp, snakes, scorpions, jaguars, reptiles: frogs/lizards

•Decomposers: earthworms, fungi, termites, bacteria

Carrying capacity

Carrying Capacity Is the balance between the availability of the habitat components and how much the habitat can support.

Resources a population needs to survive: food, space, sunlight, and water.

Sloths Changing Over time

The Sloth's population can decrease over time if its food sources becomes less in its habitat, and also by the destruction of trees.

Limiting Factors

-Limiting Factors are the factors that limit the organism from surviving.

Examples: Human Destruction, Weather, Food supply, Environment Pollution, Diseases etc.

Factors affecting Jaguars

The Jaguar population has been getting smaller because of the rapid hunting from humans(for fur) and the destruction of its habitat from man made agriculture and buildings. Also the toxic pollution makes their living more unhealthy.

Energy Roles

There are many different levels of trophic levels in the Tropical Rainforest. The levels are Producer, Primary consumers, Secondary consumers, and Tertiary consumers. One producer would be the Ceiba tree; A primary consumer would be a Howler Monkey; A secondary consumer would be a Harpy eagle and then a Tertiary consumer would be a leopard.

The producers are very important because its the only thing that gets its energy from the sun, has the largest amount of energy and its the base of the energy role

Food Webs

-Food webs are more realistic because they show the more possibilities in an ecosystem.

If one of the populations becomes extinct... then one population or organism may decrease and then another maybe increase. For example, if the harpy eagle becomes extinct, then the howler monkey's population will increase while the leopards's will decrease.

Food Pyramids

The energy pyramid is shown as a pyramid because it shows the amount of energy going from one trophic level to the next (or from one organism to the next)

The top part of the pyramid is small because it represents how only 10 percent of the energy is passed onto the next consumer. So then more you go up the pyramid less and less energy is available.

The pyramid also represents population because the bigger consumers like in the Tertiary, need more energy so there can only be some top predators sense not much energy is transported. That's why the producers are in the largest space because they don't require as much energy

10 percent of the energy that the organism receives comes from another organism thats below it in the energy food web.


Photosynthesis Equation: 6CO2+6H2O---->C6H1206+6O2

CO2=carbon dioxide; H2O=Water: O2=Oxygen; C6H12O6=Glucose

A plant needs: Carbon Dioxide, Water, and Sunlight to the produce Glucose. This process happens in the cell organelle, Chloroplast.


-when the plant absorbs sunlight, it turns into chemical energy (the making of glucose)
-once the plant has been eaten, the organism gains heat/mechanical energy


tropism is the bending or turning of an organism away/towards the external stimulus.

-The types of tropism i would mostly find in my environment are... Phototropism and Geotropism and Thigmotropism

-Phototropism helps the plants in the lower levels get their sunlight. Theres a lot of plants in the rainforest so geotropism helps them grow properly. Also theres a lot of vines too and so Thigmotropism lets the plants wrap around the other producers and objects so it the tropism lets it move around to grow.


-Decomposers are important because they help break down the dead and create nutrients for the plants; It also gets rid of the waste.

-Without DECOMPOSERS, The world would turn into a waste land and so the plants will suffer under it. Soon the plants will die meaning no food nor oxygen would be available.

-The types of decomposers you would find in the rainforest are: Termites, Velvet Worms, Leaf Beetles, Vermilion Mushrooms, Partula, Cup Fungus etc.


-It's important that an organism adapts to its environment, so it can survive and reproduce. The two types of adapting is Behavioral and Structural. Behavioral is the showing of how the organism acts. While Structural is the way organism is built physically.

Adaptations in my environment

Lianas, a wood vine, adapts by digging its roots to the ground and climbing trees to reach the sunlight it needs. Drip tips are one of the  adaptation that plants in the rainforest . This adaptation allows water droplets to fall quickly off of the leaves so the plant wont start growing fungus.

A sloth has the adaptation of claws, so it can hang onto trees and eat. Dart Frogs have poison in them so they can be protected from its predator.  

Moving to Another environment

If and organism moves to a different ecosystem, its adaptation for that certain environment will soon become useless and turn into a negative factor. For example, a sloth uses its green-algae covered fur for camouflage. So say if you place it in the desert, the sloth wont be able to blend in and be protected from its predator. Also the animal has no protection for the extreme heat, leading to a faster death.

Natural Selection

Natural Selection is the process where the organisms that tend to adapt to their environment survive longer and produce more offspring.  .

-For example, a Leopard has many adaptations that have been selected over the many years. They have a blending fur color that helps it hind from its predator. Leopards also have very good eyesight, which helps them see at night. Another adaptation would be their claws that help them climb up the tall trees and hunt prey.

The Leopard's population increased because that one population that adapted all these factors survived, So so now it can protect itself more and find food. One reason for its change is because the environment most likely grew more of its trees over time. So  the leopard had to adapt the climbing so it can get around. Another reason is that the different colored Leopards that didn't blend much in, probably got killed. Which means that the Leopards with a better fur color survived more , leading to that organism's population increased.

Check some of your spelling and capitalizations. Also, take out the # at the top. You don't need it. I love how you have multiple pictures to scroll through, but try and separate them for your biotic and abiotic factors.
