Transcript of Ecology of Pi

Ecology of Pi Glossary of Terms Food Web Energy Pyramid Analysis Questions 1. Autotroph- organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds, also called producer
2. Heterotroph- organism that obtains energy from the foods it consumes, also called a consumer
3. Consumer (1st, 2nd, 3rd)- organism that relies on other organism for its energy and food supply, also called a heterotroph. There are three types of consumers. First is primary, then secondary, then tertiary
4. Producer- organism that can capture energy from sunlight or chemicals and use it to produce food from inorganic compounds, also called heterotroph
5. Ecology- scientific study of interactions among organisms and between organisms and their environment
6. Biome- group of ecosystems that have the same climate and dominant communities
7. Food Chain- Series of steps in an ecosystem in which organisms transfer energy by eating and being eaten
8. Food Web- network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem
9.Herbivore- organism that obtains energy by eating only plants
10. Carnivore- organism that obtains energy by eating animals
11. Omnivore- organism that obtains energy by eating both plants and animals
12. Insectovore- organism that feeds mainly on insects
13. Commensalism- symbiotic relationship in which one member of the association benefits and the other is neither helped nor harmed
14. Mutualism- symbiotic relationship in which both species benefit from the relationship
15. Parasitism- symbiotic relationship in which one organism lives in or on another organism (the host) and consequently harms it
16. Predation- interaction in which one organism captures and feeds on another organism
17. Abiotic Factor- physical, or nonliving, factor that shapes an ecosystem
18. Biotic Factor- biological influence on organisms within an ecosystem
19. 10% Rule- the amount of energy being transferred when one organism eats another 1. All food chains should start with a producer in order to be successful over the long term.
2. Does it matter which way the arrows go in a food chain or food web?
Yes, the arrows show who eats who and which way the energy energy flows.
3.Do the organisms in a Food Chain or Food Web represent only 1 individual organism or multiple individuals?
Multiple individuals because it represents the other organisms in the same species.
4. Which type of factors are placed in a Food Chain or Food Web?
Both abiotic and biotic factors are placed in a food chain or food web. The sun would be the abiotic factor and the rest are considered living so they are the biotic factor.
5. List one Predator/Prey Relationship from your Food Chain
Richard Parker the tiger is the predator and eats the meerkats which are the prey.
6. How would the immigration of Pi and Richard Parker affect the island’s ecosystem? Predict future results of their intrusion on the island.
The meerkat population would decrease because Richard Parker eats them. The algae would also decrease too from Pi.
7. What would occur to your Food Web if your autotrophs exceeded their range of tolerance?
If the autotrophs exceed their range of tolerance, they would die off causing all the other organisms to die too.
8. If the autotroph in your Food Chain contains 100,000 Kilocalories (Calories), then determine the amount of energy available to the last member of your Food Chain.
100 Kilocalories
9. What would happen if the Energy Pyramid of Pi’s Island suddenly inverted?
There wouldn't be enough energy for everyone to survive so they will all end up dying.
10. Add a density independent factor to your Food Chain. List it and explain what will happen?
A density independent factor would be a hurricane. A hurricane can cause great damage to the island. It could completely destroy the island and make it gone. This would result in the meerkats to die and maybe Pi and Richard Parker if they weren't able to escape. But the fishes would be able to live.
11. Add a density dependent factor to your Food Chain. List it and explain what will happen?
A density dependent factor would be disease. If there was disease in the food chain, then an organism's population would decrease. If they weren't able to survive it, then the whole population would die off.
12. What will occur if the consumers on Pi’s Island extend past the carrying capacity of its Food Web?
If the consumers extend past the carrying capacity, then there won't be enough producers, and the consumers will eventually die.
13. Choose one organism from your Food Web and give its niche and habitat.
The algae's niche is to provide oxygen and to be eaten by some organisms. Algae is found wherever there is water.
14. What types of materials would need to be added to a Food Web in order to make it an ecosystem?
Abiotic factors
15. What is the Biome of the Island in the Life of Pi?
Tropical rain forest.

Rules:
1. Each person randomly picks out a biome card
2. place all organism cards face down
3. take turns flipping cards over to match your biome
4. the first person to get four cards that matches their biome wins example of winning hand: grass grasshopper mouse owl organism card biome card north western coniferous forest
