Transcript of Jungle Food Web

9 pd.4 JUNGLE FOOD WEB <> A biome is a large naturally occurring community of flora and fauna occupying a major habitat, e.g., forest or tundra. Biome: <> the natural home or environment of an animal, plant, or other organism. Habitat: <> all the inhabitants of a particular town, area, or country Population: <> an animal that feeds on plants. Herbivore: <> an animal that feeds on flesh. Carnivore: <> an animal or other organism that feeds on dead organic matter. Scavenger: <> an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. Autotroph: <> an organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances. Decomposer: In the picture above it shows of a brazilian tapir. Its role in this ecosystem is to consume the primary consumers and obtain some of its energy, later some of that energy will be passed to the tertiary consumer Example of a Herbivore: FOOD WEB kh GRASS SPIDER MONKEYS MANGO TREES ORCHIDS RUBBER TREES BANANA TREES such as leave cutter ants, spiders, butterflies, ect. INSECTS FUNGUS ANTHRANOSE WORMS CAPYBARAS FROGS TAPIRS JAGUAR BOA CONSTRICTOR PRODUCERS PRIMARY CONSUMERS SECONDARY CONSUMERS TERTIARY CONSUMERS a) If one of your primary consumers became extinct, analyse 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.

With the extinction of a primary consumers, the food web would have major issues. Animals will have to adapt to the new difference and learn to feed off of other plants or animals. If all the primary consumers become extinct then the food web collapse, causing extinction, migration, or possibly evolution in some way. These things will happen because without primary consumers the producers would run out of space and resources. 5/6 b)Explain how your food web would be affected if there were no decomposers involved in it?
Decomposers are one of the things needed in an ecosystem. They are organisms that take dead plants and animals and break them down into simpler substances. Take a worm for example, a worm eats the dead plants or animals in the soil, after it digests it, it disposes it, this becomes more fertile soil for other plants to grow in. Without these organisms the soil would not be as fertile. So in a jungle ecosystem they are needed to make the soil fertile for the the plants to grow g c) Primary source is the one that obtains some of the producers energy but of course every time something is eaten energy is lost. c)i) 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.

Even though the producers are always at the bottom of the food chain, plants are very important to the life of all the other life forms. For the food chain to work the plants or producers will absorb energy and that energy will then be passed up through the food web. Every time something is eaten or consumed energy is lost. Producers have the most energy. The secondary is the one that eats the primary and obtains energy. Energy is also lost. The tertiary is the one that eats the secondary and obtains the least amount of energy. d)Identify one organism in your food web that is both a primary and secondary consumer.

Capybaras can be both primary and secondary consumers. This is because it eats the producers but gets eaten by the tertiary consumer. e)Explain how two named abiotic factors in a rainforest ecosystem function to support it’s wide variety of life.
Rain and soil are two important factors in a rainforest ecosystem. Rain is the rainforest’s source of water, without rain the ground would be dry and no plants would be able to grow there. When it rains it waters the forest floor which makes it moist for the plants to grow in it. Also the force from the rain causes some leaves from the trees to fall resulting in it landing on the forest floor; when it reaches the floor all its nutrients are gathered making the soil fertile for plants to grow. f)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.

An example of parasitism in the Amazon would be between cicadas and trees; the cicada adults lay their eggs in the tree, then when they hatch, the cicada nymph drop to the ground and burrow to the roots of the tree, when they get there they sucks the sap out of the roots

THE END <> In the tropical rainforest the temperature is generally around 80 degrees with very high humidity (77%- 88%). It is very dense and wet all the time due to the fact that it rains all year round. There are many different species of plants and animals that occupy the jungle, living off each other and competing with each other. <> Waterfalls in the jungle are home to many fish and they flow into rivers which lead to the ocean Insects are one the most common organisms to see other than trees. These insects live all over the place, like in trees, or in grass. You can find them creeping and crawling in every layer of the forest from the canopy to the forest floor. Above there is a picture of a jaguar. A jaguar is a tertiary consumer that gets its energy from the food it eats (or known as secondary consumers). Its role in the ecosystem is to help balance the food web. If there were no jaguars the jungle would be overrun by its prey. JAGUAR Leaf cutter ants are one of the smallest animals in the Amazon rainforest. Living on the forest floor, leaf cutter ants are scavengers they feed on dead plant and animal remains. The role of the mango tree is to absorb The tree absorbs carbon dioxide, from the environment, using it to make the trunk, branches, leaves and fruit of the mango tree. The tree produces oxygen and releases it into the environment during this process. The mango tree does not only supply food or other animals but it gives then oxygen to breathe.. MANGO TREES The role of a decomposer in an ecosystem is to break down dead plants or animals into simpler substances. A worm is an example of a decomposer, it take the the dead plant or animal and starts to break down the substances down into simpler ones. Decomposer
