Transcript of Life of Pi ecology

by: Zayra Gallegos Life of Pi Ecology Food Chain pyramid glossary Analysis Question #2 Analysis Question #1 Analysis Question #3 Analysis Question #4 Richard Parker
teritary consumer
carnivore autotroph: An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
heterotroph: An organism deriving its nutritional requirements from complex organic substances.
1st level consumer: 1st level consumers are any heterotrophs (animals who cant produce food through photosynthesis or chemosynthesis) that eat producers( plants, bacteria, things that produce their own food).
2nd level consumer: 2nd level consumers are carnivores or omnivores that eat 1st level consumers.
3rd level consumer: A third level consumer is an animal which eats any animal in the second level category.
producer: Organisms that can capture energy from sunlight or chemicals and use it to produce their own food from inorganic compounds
Ecology: Scientific Study of interactions among organisms and between organisms and their enviorments
Biome: Group of ecosystems that have the same climate and dominant communities.
Food chain: Series of steps in an ecosystem in which organisms transfer energy by eating and being eaten
food web: network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem
Herbivore: Organism that obtains energy by eating only plants
Carnivore: Organism that obtains energy by eating animals
Omnivore: Organism that obtains energy by eating both plants and animals
insectivore: An organism that feeds mainly on insects.
commensalism :symbiotic relationship in which one member of the association benifits and is neither helped or harmed
Mulualism: symbiotic relationship in which both species benefit from the relationship.
parasitism : symbiotic relationship in which one organism lives in or on another organism and consequently harms it
Predation : interaction on which one organism captures and feeds on another organism.
abiotic factor: Physical or non living factor that scars off a leaf from the vascular system
biotic factor: Biological influence on and organism within an ecosystem
10% rule: energy that passes from prey to predator is only conserved at about 10% All food chains should start with a Producer in order to be successful over the long term . Does it matter which way the arrows go in a foodchain or food web?

Yes it does, because if you start from the top and go to bottom the carnivore would be the producer instead of the consumer and vise versa. Do the organisms in a food chain or food web represent only 1 individual organism or multiple individuals?

It can represent multiple individuals because their can be similar animals that have the same trait or consume the same food. Which type of factors are placed in a food chain or food web?

Both factors are required for the food chain/ food web because both benefit from each other. Pi Patel
secondary consumer
omnivore Algea
producer Fish
primary consumer
herbivore Meerkat
secondary consumer
omnivore Fish
2nd level
100 kcal Algae 1,000 kcal
100% autotroph
1st level Pi
10kcal Analysis question #5 List one predator/prey relationship from your food chain

Tiger and the meerkat Analysis Question #6 How would the immigration of Pi and Richard Parker affect the island's ecosystem?

They'll mess up the food chain Analysis question #7 What would occur to your good web if your autotrophs exceeded their range of tolerance?

The less algea, the less the fish will have to eat and die off. Therefore the whole food web will eventually die off. Analysis question#8 If the auto troph in your food chain contains 100,000 kilo calories, then determine the amount of energy available to the last member of you food chain.

100% Analysis Question #9 What would happen if the energy pyramid of Pi's island suddenly inverted?

The tertiary consumer will be more than the producer. Not in energy but in size. Analysis Question #10 Add a density independent factor to your food chain. List it and explain why.

A hurricane can cause massive mortality in local population irrespective of their densities. Analysis Question #11 Add a density dependent factor to your food chain. List it and explain what will happen?

Disease- a deadly disease that wipes out the algae population will cause the food chain to be imbalanced causing the consumer to die off due to lack of producers. Analysis Question#12 What will occur if the consumers on Pi's island extend past the carrying capacity of its food web?

The amount of consumers will increase, meaning the more food they'll consume. The producer might run out and theyll die off. Analysis Question #13 Choose one organism from your food web and give its niche and habitat.

The niche of algae is being a supplier of food for nutrients to a variety of organisms
Analysis Question #14 What type of materials would need to be added to a food web in order to make it an ecosystem?

producer, consumers, decomposers Analysis Question #15 What is the biome of the island in the life of Pi.(provide textual evidence)

Chapter 92-Pi talks about how green it is and mostly algea. Pi's Island Extra Credit Puma deer tree eagle rabbit grass caterpillar robin fox biome: Temperate grassland
