                                By: Hallie Anderson

Abiotic and Biotic

Abiotic: air pressure, waterfall, rocks, mist, humid air, sunlight, soil, gravel, clouds, amount of rainfall.

Biotic: Rubber and bamboo trees, sloths, anteaters, poison dart frogs, tigers, bamboo, hummingbird, dragon flies, ants, parrot.

Carrying Capacity

The largest number of individuals of 1 species that an environment supports. In the rainforest you need water, shelter, and food.

Population Increase/Decrease in Asian Big Cats

"The largest of all the Asian big cats, tigers rely primarily on sight and sound rather than smell. They typically hunt alone and stalk prey. A tiger can consume up to 88 pounds of meat at one time. On average, tigers give birth to 2-3 cubs every 2-2.5 years. If all the cubs in one litter die, a second litter may be produced within 5 months.

Tigers generally gain independence at two years of age and attain sexual maturity at 3-4 years for females and at 4-5 years for males. Juvenile mortality is high however—about half of all cubs do not survive more than two years. Tigers have been known to reach the age of 26 years in the wild.

Males of the largest subspecies, the Amur (Siberian) tiger, may weigh up to 660 pounds. For males of the smallest subspecies—the Sumatran tiger—upper range is at around 310 pounds. Within each subspecies, males are heavier than females. Tigers are mostly solitary, apart from associations between mother and offspring. Individual tigers have a large territory and the size is determined mostly by the availability of prey. Although individuals do not patrol their territories, they visit over a period of days or weeks and mark their territory with urine and feces.

Across their range, tigers face unrelenting pressure from poaching, retaliatory killings and habitat loss. They are forced to compete for space with dense and often growing human populations."

Limiting factors

"Any factor or condition that limits the growth of population in an ecosystem.

Sunlight is a limiting abiotic factor. This is due to a very dense canopy, sunlight is blocked from the rainforest floor making underbrush growth sparse.

Soil Nutrients is also a limiting abiotic factor. Rainforest soil is very acidic and provides little nutrients, plants depend on the decomposition of large fallen trees."

Preys and Predators

"This is the Poison Dart Frog it is located in the Amazon Rainforest. The poison part in there name is definitely true. A little frog being very small but extremely poisoness. Glands in the skin produce a poison, a neurotoxin, which acts on the nervous system. It eats small terrestrial invertebrates. Mostly insects like small beetles and other small prey. Also they eat small new born crickets. South American indigenious tribes used this poison on their arrow tips. It kills it's food by paralyzing the prey and then it consumes it. This tiny frog is the predator, not the prey. But it easily could be the prey in the snap of an eye. Poison Dart Frog - worlds most poisonous animal. It's poison is enough to kill 10 strong men at a go, or better still, 15,000 rats, quote from wikipedia."

Producer

An organism, such as a plant, that can produce its own food from ignorant substances.

Consumer

An organism, usually an animal, that gets its energy off a plant or other animal.

Decomposer

An organism, usually bacteria, that breaks dead cells into smaller cells.

Producer

"Bamboo, Banana Trees, Rubber Trees, Cassava, Avocado, Many tropical fruit trees such as lemon, orange etc., Air plants, Vines, Shrubs, Ferns, orchids.

Consumers

Sloth, Most bats, Humming birds, Bees, Wasps, Lemurs, Pygmy, Marmosets, Opossum, Sloth, Most bats, Humming birds, Bees, Wasps, Pygmy, Marmosets, Opossum.

Decomposer

Earthworms, Fungi, Termites, Bacteria, Protozoan, Other single cell creatures, Other Insects, and parasites."

Energy Roles

Each organism receives energy from its prey, or the organism below it in the energy pyramid. For example a jaguar gets its energy from frogs, monkeys, macaws. You must have a producer because producers make their own food, and so they are the start of the food web. They are the only organisms who can make their own food so they are really needed.

Energy Food Web

Food webs are more realistic then food chains because the animals eat several different things such as a jaguar eats macaws and monkeys, and pythons eat macaws and fruit bats. In a food chain it is just coconut trees-grasshoppers-frogs-jaguars. As you can see above more than one thing eats the coconut tree, the grasshoppers eat different things, different things eat the grass hoppers ect.

If I were to remove the grasshoppers, then the frogs would die out because they only eat grasshoppers and that's their food source. The frogs would eventually die out, and then the jaguar would have limited food sources and they would have to fight for food causing some to die out.

A pyramid is the perfect shape because it shows the amount of energy moving up with the organism. The organism only gets 10% of the energy from its prey because the prey uses the other 90%. The energy amount gets smaller as it goes up just like a pyramid.

The reason why the producers are at the bottom of the pyramid is because they get 100% of the sun's energy while the primary consumer, secondary consumer, and teritary consumer only get 10% of its prey's energy.   

Photosynthesis Chemical Formula

The chemical equation using the chemical formulas for all substances involved in photosynthesis is...

What is needed for plants to survive?

For photosynthesis this is what is NEEDED (the reactants) in order for the plant to survive- carbon dioxide, water, and light.

What does the producer produce?

This is what is PRODUCED (the products) by photosynthesis- glucose. Glucose is the food that a plant makes for its self to eat. Glucose is made up of water and oxygen.

Where does photosynthesis occur?

   Photosynthesis takes place inside the plant's cells in things called chloroplasts. Chloroplasts contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.

Energy transformation taking place during photosynthesis

Tropism

turning or bending movement of an organism towards or away from an external stimulus, such as light, heat, or activity.

In the rainforest some examples of tropisms are vines growing up a tree, which is an example of thigmotropism and phototropism.

Tropism helps the rainforest because when decomposers break down dead organisms to provide nutrients for plants.

Decomposers

Decomposers are so very important to the environment because they break down dead plant and animal cells and return the nutrients to the earth. The nutrients helps keep the trees healthy, so we really need them. If we didn't have decomposers, we would be living in a waste land, and we wouldn't have healthy tees.

In the rainforest, you would find all sorts of decomposers. Some of them include Earthworms, Fungi, Termites, Bacteria, Protozoans, snails, slugs, millipedes, mites, and more!

Adaptions

Adaptions are important because the animals need to survive in the rainforest and they need to be able to adapt to the environment. They might need to learn how to live in trees or hunt for their food. Without adaptions animals would die out because they would not know how to survive in a different environment.

Since the rain forest has many trees, a good adaption would be the one that allows animals to be able to climb and hunt for food in trees. Monkeys and sloths are good examples of this.

    The second could be the adaptation to being able to swim and cope with a lot of rainfall. Turtles and snakes are a good examples of this.

Lianas are climbing woody vines that drape rainforest trees. They have adapted to life in the rainforest by having their roots in the ground and climbing high into the tree canopy to reach available sunlight. Many lianas start life in the rainforest canopy and send roots down to the ground.

If I were to put a random animal in the rainforest who lives somewhere else, it would have to learn how to climb trees, live in trees, and hunt for food in trees. It would also have to survive in the humid air, and find a close source of water.

Natural Selection

the process by which different organisms have traits that better enable them to adapt to specific environment setting such as, predators, changes in weather, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus ensuring the perpetuation of those favorable traits in succeeding generations.

In a habitat there are red bugs and green bugs. The birds prefer the taste of the green bugs, so soon there are many red bugs and few green bugs. The red bugs reproduce and make more red bugs and eventually there are no more green bugs. So then the birds stopped eating these bugs because they did not like the red bugs and they found something else to eat. Then the birds had to fight other animals for that food and the sources went down.

I agree with this because you didn't just say temperature or rainfall, you said "amount of rainfall", and "humid air"!!😉 😃 👍

It looks AWESOME! The only thing I have to add is this: are you planning to add step 11? It covers adaptations, but I didn't see it when I was scrolling through.
