The Rainforest

Biotic Factors: Living factors in an ecosystem

Animals: African forest elephant, Bengal tiger, Chimpanzee, Dawn bat, Harpy eagle, King cobra, Jambu fruit dove, Toco toucan

Plants: Bengal bamboo, Bougainvillea, Curare, Coconut tree, Durian, Jambu, Kapok tree, Mangrove forests

Abiotic Factors: Non-living factors in an ecosystem

Abiotic factors: Rocks, Hot temperatures, water/Rain, Humid air, Sun light, Rich soil, mist/fog

Carrying capacity

Carrying capacity is the largest number of individuals of one species that an environment can support. The resources that are needed to survive are food, water, shelter, and space.

Populations change over time, one example is Bengal tigers in the rain forest. The tigers need the certain resources to live, but the don't always get them. If they don't get the required resources they die, decompose, then turn into nutrients for other animals.

This shows the population of tigers in the Rainforest.

Limiting factors

Limiting factors are any factors or conditions that limit the growth of a population in an ecosystem. Some examples are limited resources, extreme temperature/weather, large numbers of predator or small numbers of prey, and habitat distruction.

The tiger is stalking his/her prey. The tiger is a limiting factor for the monkeys.

Energy Roles

Energy roles are determined by how an organism gets energy and how it interacts with other living things in and organisms. The main energy roles are producers, consumers, and decomposers. Some energy roles in The Rainforest are Bengal tigers durian, and various mushrooms.

Food Webs and Food Chains

Food webs are more realistic than food chains because food chains are in one ecosystem and food webs are overlapping ecosystems. If you removed the tigers then all of the tiger's prey would over populate and eat up their food source. Then the same thing would happen to other organisms until the ecosystem failed all together.

Trophic Levels and Energy pyramids

An energy pyramid is shaped as a pyramid because the bottom layer gets the most energy and each layer gets less energy going up. each layer going up gets about ten percent of the previous layer's energy. Producers are at the bottom and top consumers (tertiary consumers) are at the top. This shows how producers get the most energy from the sun and turn it into chemical energy. once the energy finally reaches the top consumer other animals have already used the energy, so the top layer gets the least energy.


This graphic shows the chemical equation for photosynthesis...

What is needed for photosynthesis is water, sun light, and carbon dioxide. Photosynthesis produces glucose and oxygen.


Tropisms are a biological phenomenon, indicating growth or turning movement of a biological organism. The types of tropisms are phototropism, geotropism, hydrotropism, thigmotropism.

This is an example of thigmotropism because the vine is wrapping around the stick

Tropisms help the organisms survive by being able to find important resources.

The Role of Decomposers

Decomposers are important because they decompose all of the dead organisms to make nutrients for the plants. If there were no decomposers then all of the plants would die and then all of the animals would die. Some types of decomposers in my ecosystem are various types of mushrooms and fungi.


The purpose of having adaptations is to allow an organism change in order to survive, this could be either behavioral or physical changes. Some adaptations in the Rainforest are the tigers stripes, they let the tiger be camouflaged. Another one is durian's terrible taste and smell.  

If you placed one of the animals from the Rainforest into another ecosystem they could not survive for very long because they would be adapted to the Rainforest. They wouldn't know what to eat or what not to eat, whereto go, etc.

Natural Selection

Natural selection is when one inherited trait becomes more common in a population over many generations. Natural selection is important because it allows a population to become more adapted to their ecosystem.

These caterpillars are an example of natural selection in the Rainforest because they have grown to look like snakes over many generations. This disguise helps make predators scared of them and not try to eat them.

Add a picture for carrying capacity and add more detail to the predator/prey relationship.

This is a good tackk, you have very good pictures.

You should add a picture on carrying capacity, and you should work on steps 5-7. However, you did a great job!😃
