The Rainforest

Biotic Factors: Living parts of the Rainforest

















Abiotic Factors: Nonliving parts of the Rainforest





Lack of sun(near the floor)

Thick air



^Above the are large rocks, water and sunlight- all examples of abiotic factors to an ecosystem.

Carrying Capacity

Carrying capacity is the largest number of individuals of one species that an environment can support.

Frogs in the Rainforest

The population of Frogs would change depending on the availability of resources because if there was a shortage of any resource(a result of limiting factors) which are *Food,Space, Shelter, and Water* the competition for what they need would increase and some frogs may not get what is necessary, so they would not survive.

Limiting Factors-

Any factor or condition that limits the growth of a population in an ecosystem.






In the forest, Tigers eat birds. If humans cut down trees, the birds won't have anywhere to live. If there is a disease, the bird population could decrease and other animals won't have a food source, so their population could decrease too. Also, many animals could get sick and die from pollution and other animals will be left to starve.

Energy Roles

Energy roles are determined by how the organism gains energy and how it interacts with other living things in an ecosystem. There are three main energy roles:

>Producer___ Trees, Bamboo,Strangler Figs,Orchids,many types of flowers, and much more.

>Consumer___( There are Primary, Second, and Tertiary consumers) Sloths,Jaguars,Frogs,Parrots,Toucans and many more,including insects.

>Decomposer__Saprophytes, Mycorrhizals, and mushrooms.

The *producers* receive their energy from the sun, and then their energy goes to the *consumers*(2nd,3rd,and 4th levels) and then from there,the energy goes to *decomposers.* Therefore, all organism's energy came from the sun.

Producers are vital to the ecosystem because they are the  _only_  organisms that can take energy from the sun- Radiant energy- and transform it into chemical energy for eating.

Food Chains and Webs

Food webs are more idealistic than Food chains, because while the food chain shows only one line of predator-prey relationships, food webs are a lot of interconnecting food chains,and  are much more accurate as they show all the possible prey for a predator.

If I was to remove an organism -predator or prey- a species would suffer and another would thrive. If I removed the predator, the prey would thrive, since there is nothing hunting them down and eating them, but the animal hunting the predator will have nothing to eat, so its population will decrease. If I was to remove the prey, the predator population would decrease because there would be nothing to eat.

Trophic Levels and Energy Pyramids

An energy pyramid is shaped like a pyramid because as you go up the pyramid, it get smaller, much like the amount of energy decreasing as you move from the bottom to the top.

Producers have the largest level because they have the largest energy available whereas the predators have a smaller level because once you get to their level, most of the energy has been used.

For photosynthesis to occur, the plant needs Carbon Dioxide, Sunlight and Water. Then, when photosynthesis is over, Oxygen and Glucose is produced.

Most photosynthesis takes place inside an organelle located inside the plant's leaf called a chloroplast.

The energy transformation that occurs during photosynthesis is Radiant(Solar) energy, to Chemical energy, and then the plants food, or glucose, is eaten and then further transformed into mechanical energy.;-)



Plant movement toward or away from a stimulus.


Plant movement in response to sunlight.


Moving towards or away from the earth.


Moving towards or away from touch.


How a plant grows in response to water.

*All of these tropisms could be found in my environment, most plants move in the direction of sunlight, an example of Phototropism, and almost all plants are affected by geotropism- the roots grow downward(positive) and the shoot grows in an upward direction(negative). One example of of Thigmototropism is the Touch-Me-Not which can be found in the rainforest.


There are Saprophytes, Mycorrhizals ,earthworms, termites, and, while rain is not a decomposer, it is constantly washes away nutrients on the forest floor.

Decomposers are vital to any ecosystem because they refresh the nutrients needed for plants, and get rid of all the waste that would otherwise be laying on the forest floor.


Adaptations are crucial to my environment-or any environment because if anything was to change in that environment, you could be left without what you need to get necessary resources and would die. You would need to adapt so you could get what was needed- whether you need be faster, camouflage, or longer claws to reach food.

Adaptation Examples

Some plant adaptations would be the bark found on the rainforest trees. The bark grows and is smooth, so vines cannot grow up and choke it. There are also Lianas which are vines that grow up trees to reach the rainforest canopy for light(phototropism). One more example of plant adaptations is the drip tip, which is a leaf that allows rain to drip off the leaf, preventing fungus and bacteria growth on the plant.

An example of an animal with an adaptation would be the sloth. It moves very slowly-so much so that blue-green algae grows on its fur camouflaging it with a tree. Another animal adaptation is the poison dart frog; its brightly colored body warns predators not to eat it. One last example is a parrot's beak- it is a strong beak that can crush extremely hard shells.

If I placed another organism from my environment into another- besides its death, the organism would adapt(hopefully) and, assuming it survives, it would reproduce and the species would continue to adapt over many generations.

Natural Selection

Organisms inherit traits best suited for their environment so they can survive and reproduce, passing these traits down a hereditary line.

This is very important for organisms in any environment because if they don't have the traits they need, they cannot get the resources they require, and will be eaten or will die of starvation,lack of space, or dehydration.

There are many trees in the rainforest, and most trees in the forest have drip tip leaves. Over time, the leaves slowly changed structure to allow water to drip off. The tree population rose, because they were not dying from fungus and bacteria.The environment was constantly wet, and the trees had to change in order to survive.
