Rain Forest Ecosystem

Abiotic Factors

Moist/humid air

Rain(50 to 120 in yearly)

Temp(rarely above 93 degrees or below 68 degrees)

Humidity(between 77 and 88%)

Carrying Capacity

Without much rain many animals in the rainforest wouldn't survive. They've adapted to the environment and are quite used to how things work in the rainforest.

Limiting Factors

Some of the Jaguar population might die out if monkeys were to go extinct, though most would survive from all the other things Jaguars eat.

Energy Roles

The consumers obtain their energy by eating the organism before them while the producer gains energy from the sun. Producers are important to any ecosystem for they are where the energy starts.

Food Chains and Food Webs

Food webs give more examples of the things organisms eat and are eaten by.

If Jaguars were taken from the ecosystem monkeys, macaws, and frogs would survive a little longer before they're eaten by something else.

Trophic Levels and Energy Pyramids

If the pyramid was in another shape it would be hard to tell which the energy flow is. The reason for producers being on the bottom is because they have the most energy and there's a large amount of them. The tertiary consumers are on top because there's not much energy and there fore not many of those consumers.



Sunlight, water, and carbon dioxide are needed for photosynthesis. It makes food for the plant and oxygen for us.

Photosynthesis happens in the chloroplasts which are filled with little green substances known as chlorophyll.

Light Energy -> Chemical Energy


A tropism is the movement of an organism toward or away from an external stimulus, such as light, heat, and gravity.

Thigmotropism is to turn toward or away from touch and geotropism is the movement toward or away from the Earth.

The Role of Decomposers

Decomposers would help the many other plants in the ecosystem by adding nutrients to the soil. Without them, a majority of the plants in the rainforest wouldn't survive.

Saprophytes, Velvet Worms, Termites, and Leaf Beetles are examples of some decomposers.

i agree with this because it looks good and you have good detail

@laurenmccree It looks very clean and organized so far; keep up the good work. You also need to make sure that you are providing all of the definitions you were asked for. Also, I noticed on energy roles that you didn't give any specific organisms (what are some producers, consumers, etc. in your ecosystem?). Same thing on tropisms-- you have a picture of a plant that uses thigmotropism, but didn't actually name it.
