Transcript of Jungle Food Web

Definition: Biome
A biome is defined as a biotic group of interacting particular plants and animal species. They live under the same climatic conditions provided by the region and must adapt to it since it is a prevalent factor for the community.

Example: the jungle biome
Jungles are characterized by their large trees that cover up most of the area. They belong to the wet climate group of biomes due to their constant rainfall during their almost year-long season of rain. The large variety of animals found in a jungle vary from all the way to very small animals such as bats all the way to tigers.

Define: Habitat
An animal, plant or other organism's natural home or environment is called a habitat.

Example: A tiger's habitat is usually a jungle, though they can also be found near swamps and in grasslands. Their habitat requires a large area of plants and pasture where they can hide, plus a good population of prey.

Describe: Population
Population refers to a section or group of people or animals that live in an area or country and are considered to be the inhabitants of that specific area.

Example: The Linn's sloth occupies a portion of the jungle area, iIt has a white/tan face and the fur is black/dark brown.
An animal that partakes in their environment by feeding on plants.

Example: A tapir is the largest rodent in the world. They feed from grazing mainly on aquatic plants, grasses, as well as tree bark and fruit.

Define: Carnivore
A carnivore is mainly an animal that feeds off flesh and meat. Carnivores have to hunt down and kill other animals they require a large amount of calories.

Example: All snakes have one thing in common, they all eat meat. Snakes rely on other species of animals to keep them alive.

Define: Scavenger
A scavenger is considered to be an animal that feeds on carrion (the decaying flesh of dead animals) and also dead plant material.

Example: An example of a scavenger found in the jungle is a vulture. They don't hunt, instead they eat decaying matter of other animals and feed off from scraps left by predators.

Define: Autotrogh
An organism that is able to produce its own food from chemical or light energy. Green plants, bacteria, protists (one-celled organisms like slime molds) are considered to be autotrophs.

Example: In the jungle, as many other biomes around the world, plants are considered to be autotrophs since they are able to synthesize their own food from inorganic substances,
Define: Decomposer

A decomposer is an organism that plays an important role in an ecosystem, it breaks down dead plants and animals as well as other organism's waste.

Example: An example of a decomposer is a cockroach, it feeds off dead and decaying plants and animals. After the scavenger has done his work, the decomposer takes over and finishes the job.

If one of your primary consumers became extinct, analyze how three other biotic factors/species would be affected. For example would the populations of these species increase or decrease as a result of the extinction? Explain your response.

For example if one primary consumer; for example the grasshopper would become extinct the following consumers would definitely be affected. The grasshopper provides nutrients and energy for many different species, among them there are frogs, birds and spiders. With the extinction of grasshoppers these animals would need to rely on other primary consumers to enrich them with the energy and nutrients they extract from plants. This might end up in a chaos within the food chain making it unstable and eventually reduce the population.
Explain how your food web would be affected if there were no decomposers involved in it?

An ecosystem's food chain mainly shows the physical transfer of matter and of energy from one organism to another. Decomposers are often categorized as non-important or simply forgotten, yet they are one of the most important organisms that play an immensely significant role in the food web. As they break down the "leftovers" they intake the last energy left from the chain. With what they intake they are able to release nutrients into the air, soil or water which is later taken in by the plants and all those considered to be producers, regenerating the food chain. Without the assistance of the decomposers, all of the remaining energy and nutrients would remain inside the animal's or plant's dead "body" not being able to give it to the following organisms that allow the process to re-create. We could consider them to be the bridge of interaction between living and non-living organisms in a food web. Given this information, it is clear that a food web without decomposers would end up disintegrating the sequence of development of each of the organisms that partake in the web.
Explain why there are normally more producers in a food web than tertiary consumers? ii) In your Prezi, create and label a pyramid of energy from one food chain found in your food web.

Producers are organisms that are considered to be autotrophs, meaning that they produce their own food for chemical or light energy. Mainly their job in the food web is to provide all of the rest with energy and nutrients allowing the chain to continue. There are so many of these types of organisms since they are the physical source for any other living thing which is why they are located at the bottom of the food chain; showing that they are what starts it all. By having a larger amount of tertiary consumers in a food web, it would all subside. This is because consumers don't have the ability of providing organisms prior to themselves with nutrients and energy they need. This would end up in no form of renewing the food chain having it start again as it would with a large amount of producers forming part of it.

Identify one organism in your food web that is both a primary and secondary consumer.

After doing a bit of research, an organism that can be considered both primary and secondary consumer is the beetle. There are many different species of beetle, some are herbivores due to the fact that they eat plants and vines living in a jungle environment. But, not all belong to the primary consumer group, but as well as the secondary consumers group. To be categorized as a secondary consumer the organism should ingest primary consumers meaning that they are considered carnivores. An example of a carnivorous beetle belongs to the Family Histeridae and consumes small arthropods, earthworms and snails. In conclusion, we can see that beetles can fit both categories since in their vast variety of species there are both herbivores and carnivores.

Explain how two named abiotic factors in a rainforest ecosystem function to support it’s wide variety of life.

In a rainforest ecosystem two named abiotic factors that are significantly important to the ecosystem's function are water and sun. Light provided from the sun allows the process of photosynthesis to occur. What this process consists of is the sun providing the plant/receiver with the sufficient amount of energy and vitamins to produce it's own food using the energy of the sun. Later, the consumers who eat the plants and producers intake that energy and those stored vitamins from the plants. Water also provides the plant with nutrients for its development and its fundamental role in a food web. Beneath and between the rainforest/jungle soil there is water. The roots extract the nutrients as they absorb the underground water, this moisture and nutrients are then conveyed through the leaves and stem providing the plant with food,

Find an example of parasitism that occurs in rainforest ecosystems and describe it briefly below. Be sure to identify both the parasite and host organism in this biotic interaction.

Parasitism is basically the relationship between two organisms where one benefits and the other is harmed. An example of a parasite is a leech. They are commonly found in freshwater, though some are also found in terrestrial areas and marine environments. They live by feeding on blood from invertebrate or vertebrate animals by clinging onto them. It is clear that these parasites benefit from the extraction of blood they go through to receive the nutrients and energy they need. The hosts are mainly mammals, though leeches can feed off from any organism big enough that provides them with what they need.
