The Rainforest

Biotic Factors

ANIMALS: Frogs, Jaguars, monkeys, birds, Tigers, snakes, elephants, insects, pandas, and lizards.

PLANTS: Banana tree, orchid, coffee plant, Brazil nut, poinsettia, cacao tree, rubber tree, heliconia, sapodilla, and bromeliad.

Abiotic Factors

Water, warm climate, sunlight, soil nutrients, rocks, heavy rain, and lightning.

Carrying Capacity and Changes in Population

    Carrying capacity is the number of living organisms that a region can support without environmental degradation. The resources needed for a population to survive are food, water, shelter, and space.

    In the Parrot population, if there were to be a disease in some fruit trees, there would start to be a shortage of fruit, which would also affect the insects diet, so there would be very few insects or fruit for the parrots to eat, so they would die of starvation.

As the fruit and insects die, the parrot population also decreases.

Limiting Factors and Predator/Prey Relationships

   Limiting factors is resources or environmental conditions that limit the growth of a population. Some examples of limiting factors in the rainforest are sunlight, because of the very shaded forest floors. Another example is deforestation, humans convert some of the forest into their homes, which causes habitats to be gone.

   A predator/prey relationship in the rainforest is a frog hunting insects. Limiting factors that can affect frogs are chemical contamination, that kills frogs, and they could become extinct, which could cause an over population in insects.

Energy Roles

Energy roles are the quantitative measure of the production of energy by an organism. Some examples of energy roles in the rainforest are the sun, leaves, insects, frogs, snakes, and birds.

   The leaves get it's energy from the sun, the insects get it's energy from the leaves, the frogs get it's energy from the insects, the snakes get it's energy from the frogs, and the birds get it's energy from the snakes.

    Producers are vital to an ecosystem because they are the base of our food chain. Primary consumers and tertiary consumers eat the producers.

Food Chains and Food Webs

Food webs are more realistic than food chains because it shows more individual predator/prey relationships.

If I were to move squirrel population from the food web, there would be a shortage of food for the Crowned Eagle, Leopard, and Python. They would probably die because of starvation.

Trophic Levels and Energy Pyramids

The shape of the energy pyramid is a triangle because it shows the amount at which energy flows. Producers are the largest level because they hold the most energy, and top predators are the smallest level because they hold the least amount of energy. This represents the trophic levels.


Chemical equation for photosynthesis: CO2+HO2---->C6H12O6+O2oooooo

      For the process of photosynthesis, there would have to be chlorophyll, the sun, water, and carbon dioxide would have to be present. Photosynthesis produces oxygen and sugar.


A tropism is directional movement responses that occur in response to a directional stimulus. One example of a tropism in the rainforest is when a Banana tree moves due to the sunlight. Another example is when a snake bites a leopard, the leopard instantly reacts to the bite, or touch of the snake, thigmotropism.


Decomposers are vital to the rainforest ecosystem because they enrich the forest floor's soil and promote growth of living plants and animals by increasing levels of certain nutrients. If there was no decomposers, there would not be enough nutrients in the soil and the producers would die because of lack of nutrients.

Some examples of decomposers in the rainforest are worms, fungi, mushrooms, bacteria, and small anthropods.


Without the capability of adaptation, there would not be any order in nature. Leopards adapt to their surroundings by camouflage, endurance, orientation, and "hunting tools" (teeth, claws, speed, and strength). Without those adaptations, the leopard would die.

If the leopard from the rainforest got transported into the tundra ecosystem, the leopard probably wouldn't survive very long due to the very cold climate and snow. The leopard would definitely stand out in color because of its brown color against ice and snow. Because it would stand out, it would be an easy land target for the polar bears.

Natural Selection

Natural selection is the process of having traits that better enable them to adapt to specific environmental pressures. Natural selection is important because it is responsible for adaptations of organisms o their environment.

The toucans beak is a part of natural selection. Its beak attracts mates, keeps the toucan cool in temperature, and peel fruit. This helps the population increase because it is able to survive well in its environment.
