Bio test 2! Flashcards
List the levels of organization of life (6; start with individual ends with biosphere)
Individual, Population, Community, Ecosystem, Biome, Biosphere
Flow of Energy (starting point and direction)
In a line from the sun to plants and to diff levels of consumers
Primary Producers
Organaisms that acquire energy from the sunlight or other non-living sources
Herbivore, Omnivore, Carnivore, Scavenger
Plants, both, Animals, Dead Stuff
Decomposes and Detiviours
Decomposes break down dead matter into the environment, and Detiviours break it down even more, or digest it instead of breaking it down.
What is the 10% rule?
Each time energy gets transferred 90% is lost as heat and 10% energy is given.
What is the difference between an Niche and Habitat
A Habitat is where an organism lives and a Niche is what they do. Habitats focuses on how the environment impacts the Organism, and a Niche focuses on how an Organism impacts the environment.
Difference between Interspecific and Intraspecific
Interspecific competition occurs between different species and Intraspecfic competition occurs with the same species.
Difference between Food Web and Food Chain
A food chain shows who eats who, a food web shows all the damn food chains in an ecosystem #CRAZY!
Keystone Species
A species where other species heavily depend on it in an ecosystem. If they were to be removed the ecosystem would change. #COOL!
Abiotic vs Biotic Factors
Biotic is living things in an ecosystem and Abitoic being non-living. But what is Living and Non-living? #VIRUS!
Predation (Predator vs Prey relationship
Predation: an interaction in which one animal (predator) captures and feeds on another animal.
Predators can affect the size of the prey population in a community and determine the places where prey can live and feed.
How does water get recycled
Water goes up into the atmosphere and than falls back down.
How does Carbon get recycled
Carbon goes into the atmosphere, plants take in carbon for photosynthesis, animals eats plants, they poop it out and carbon goes back into the atmosphere. Oceans also absorb carbon
How does Nitrogen get recycled
Nitrogen can’t get absorbed by plants so the soil bacteria converts nitrogen into Ammonia this process is called Nitrogen Fixation, than more bacteria convert it into nitrates, where plants can take in, than nitrates get converted into nitrites, and back to Nitrogen this is called dentrifcation
