plants/bushes-deflect the sunlight, so it is very dark.

sticks-make the area tighter.

bugs- surround the trees and eat leaves.


dirt/soil: trees release seeds and land in the soil to grow.

water: allows plants to grow for food.

sunlight: there is plentiful lights above the trees, but barely any below.




Carrying Capacity

Resources that a population needs to survive in a jungle would be enough plants: trees,fruit/vegetables. another thing would be water to help the plants grow and for the animals to drink. another important resource would be shelter. shelter is for the animals to protect themselves in or sleep in. the last important resource would be the air. if there is bad or smokey air, the animals and plants would die out.

Limiting Factors

There are a lot of preditors in the jungle. Snakes are the main preditor in the jungle. They eat rats, mice, and some could eat other predators too. Predators can decrease the population of many animals by eating them.

Energy Roles

Producers are living organisms that produce their own food.

Consumers are living organisms that go out and get their own food from plants or other animals.

Decomposers are organisms that decompose or recycle dead organisms.

Herbivores eat nothing but plants.

Carnivores eat other animals.

Scavengers eat other dead animals.

Producers are extremely important to any ecosystem because without them, there wouldn't be any animals in that ecosystem. The reason for that is because of the food webs, consumers eat plants, and other consumers eat other consumers. The population of the consumers that eat plants would decrease, then the consumers that eat other consumers would decrease until there are no more animals in that ecosystem.

Food Chains and Food Webs

Food webs are more realistic than food chains, because food webs show multiple kinds of plants or animals instead of only 1 type of plant and animal.

If there wasn't any grass in this food web, the first animals to lose population would be the tapir and the capybara. Then, the population of carnivores would decrease, and the population of monkeys and toucans would increase due to the decrease in population of carnivores.


Carbon Dioxide: CO2


Oxygen: O2

Glucose: C6H12O6

What is needed for photosynthesis is carbon dioxide, energy from the sun, and neutrients from the water. What is produced from the plant is sugar/glucose, and oxygen. The energy from the sun is transferred into the leaves, the water from the roots, and carbon dioxide from humans and animals.


Tropisms: is a growth or turning movement of an organism, usually a plant, in response to a stimulus. This is important to the plant so it can help it grow and live.

The Role of Decomposers

Decomposers are vital to the ecosystem, because they act as a recycle to the dead plants and animals. If there were no decomposers, then there would be dead animals, plants, and leaves everywhere.


it is important to have adaptions, because organisms need them to survive. It helps organisms survive by adjusting to the environment and doing things they wouldn't normally do. Like this tree. It spreads its roots out more to stand higher or to help it stand. Without this adaption, the tree wouldn't be standing up straight.

Natural Selection

Natural selection is  the process of an organism adapted to the environment to survive and produce more offspring. This is important to keep an organisms population.

A tree in my yard has been naturally selected by growing stems out more to reach light that other trees have. It changed like this to get more sunlight it needs to create its own food.

I have a question about "sticks" as your biotic factor. What do you mean by sticks making the ecosystem tighter? How does this affect the organisms in this ecosystem?

Also, I recommend that you include a title for your Tackk so that everyone knows right away what your ecosystem is.
