Ecology

By Ashley Olsen


What is ecology
What is ecology?

  • Ecology is the study of the relationship between the environment and living organism

  • Their interactions


What are individual organisms
What are individual organisms?

  • Individual organisms are the smallest unit that an ecologist would concern themselves with


What are species
What are species?

  • Species are the same organisms (as a group) that live in the same location at the same time.

  • They are capable of breeding and producing fertile young


What are populations
What are populations?

  • Agroup of species

  • They may or may not interact with one another

  • These populations make up a community


What are communities
What are communities?

  • They are a group of all the populations interacting with each other


What are ecosystems
What are ecosystems?

  • Ecosystems are a group of habitats

  • When you put different habitats together, you get ecosystems


What is a biosphere
What is a biosphere?

  • A biosphere is all of the places on Earth and where the atmosphere/oceans/caves etc. where life exists


What is a habitat
What is a habitat?

  • A habitat is where all of the biotic interact with the abiotic features


What are abiotic factors
What are abiotic factors?

  • Abiotic factors are non-living factors in the environment


What is the first tropic level producers in the food pyramid
What is the First Tropic Level/ Producers in the food pyramid?

  • The first level is equal to something taking a step up in the pyramid

  • There is the most energy that comes from the sun


What is the second tropic level primary consumers in the food pyramid
What is the Second Tropic Level/ Primary Consumers in the food pyramid?

  • The second level is the first level of consumers

  • A consumer = a heterotroph

  • Herbivores


What is the third tropic level secondary consumers in the food pyramid
What is the Third Tropic Level/Secondary Consumers in the food pyramid?

  • A heterotroph

  • Carnivores and/ or omnivores

  • Consume the primary consumers and maybe the producers


What is the fourth tropic level tertiary consumer in the food pyramid
What is the Fourth Tropic Level/Tertiary Consumer in the food pyramid?

  • The top of the pyramid

  • Third level consumer but its on the fourth level

  • Carnivores or omnivores that consume primary consumer and things below them


What is the fifth tropic level quandary consumer
What is the Fifth Tropic Level/Quandary Consumer food pyramid?

  • The Fifth Tropic level is when you rarely get a Fourth level consumer

  • This level doesn’t have enough energy to supply them

  • In this level there is .1 calories of energy


What is the flow of energy in a tropic level
What is the Flow of Energy in a Tropic Level? food pyramid?

  • A you go down in the pyramid, the amount of food required for you to consume gets larger and larger

  • It is impossible to supply if there are large quantities at the top of the pyramid


What is the difference between a food pyramid and a food web
What is the difference between a food pyramid and a food web?

  • Food Pyramid: It may talk about different types of animals and plants or it may talk about one type.

  • Food Web: It talks about many types of animals and plants


What is a decomposer
What is a decomposer? web?

  • A decomposer is an organism that breaks down dead animals and recycles the material back into the environment


What is an autotroph photosynthesis
What is an autotroph (photosynthesis)? web?

  • An autotroph is an organism that is capable of making its own food

  • Carbon Dioxide + Water + Sunlight = Glucose + Oxygen


What is a heterotroph
What is a heterotroph? web?

  • A heterotroph is an organism that is not able to make it’s own food and it gets its nutrients from other sources


What is an herbivore
What is an herbivore? web?

  • An herbivore is an organism that only eats plants


What is a carnivore
What is a carnivore? web?

  • A carnivore is an organism that only eats meat


What is an omnivore
What is an omnivore? web?

  • An omnivore is a organism that eats both meats and plants; eats everything


What is a saprobe
What is a saprobe? web?

  • A saprobe is a form of decomposers, like bacteria, that help to recycle materials back into the environment


What is a scavenger
What is a scavenger? web?

  • A scavenger is something that can eat dead things


What is carry capacity
What is carry capacity? web?

  • This is the amount of individuals in a species that an amount of land can support


What are limiting factors
What are limiting factors? web?

  • Limiting factors have access to resources.

  • These resources are food, water, shelter and money


What is density dependent
What is density dependent? web?

  • Food is density dependent

    • The more people you have, the less food you will have

  • They are all affected by population


What is density independent
What is density independent? web?

  • Density independent is when everyone is equally affected no matter how many individuals there are


What is the competition between and among species
What is the competition between and among species? web?

  • Between – food, shelter and water

  • Within the same species – food, shelter, water and mates


What is symbiosis
What is symbiosis? web?

  • Symbiosis is the way two or more organisms interact with each other


What is competition
What is competition? web?

  • Competition is an interaction between organisms or species, in which the fitness of one is lowered by the presence of another.


What is mutualism
What is mutualism? web?

  • Mutualism has an equal relationship

  • Both organisms benefit from this, no organisms are harmed


What is parasitism
What is parasitism? web?

  • Parasitism is when one animal benefits (the parasite) and one organism is harmed (the host)

  • They do not want to kill the host, they want to make it as sick as possible

  • If the host dies, the parasite will most likely die


What is commensalism
What is commensalism? web?

  • Commensalism is when one organism benefits and the other organism neither benefits nor harmed


What is the predator prey
What is the predator/prey? web?

  • A predator is the one who hunts

  • The prey is the one that is hunted

  • The predator population lags behind the prey in numbers

  • The prey population is lower


What is amensalism
What is web?amensalism?

  • Amensalism is when One organism benefits and completely destroys/kills the other organism


What is the j curve
What is the J-curve? web?

  • Tend to be small

  • To produce a lot of young

  • They reach sexual maturity at an early age

  • They have little or no parental evolvement

  • This is affected by the environment


What is the s curve
What is the S-curve? web?

  • Tend to be large

  • Produce only a few young

  • Reach sexual maturity later

  • They have a lot of parental care

  • The environment is a very important factor in their life
