Unit 2 Quiz Flashcards
A particular location on Earth distinguished by its particular mix of interacting biotic and abiotic components
ecosystem
_____is an interaction between two different organisms living in close proximity to one another.
symbiosis
_____ is a relationship where one species benefits and the other is neither helped nor harmed.
commensalism
_____ is a symbiotic relationship in which both species benefit.
Mutualism
______ is an interaction in which one organism lives on or in another organism (host).
Parasitism
____ is a symbiotic relationship where one organism survives by consuming the other.
Predation
The struggle of individuals to obtain a shared resource is known as
competition
A type of predation where animals consume producers is called
herbivory
______ often leads to an oscillating effect within data/graphs. More specifically, it is a type of regulation in biological systems in which the end product of a process in turn reduces the stimulus of that same process.
Negative feedback
_____ is a strategy used by organisms in order to share resources (helps alleviate competitive exclusion).
Resource partitioning
The _____ states two species competing for the same resource cannot coexist.
competitive exclusion principle
The ____ states when one organism consumes another, not all of the energy is transferred to the consumer.
second law of thermodynamics
_____ are organisms like plants, algae, and some bacteria that can use the sun’s energy to produce food energy for themselves.
Producers
____ is a process that converts carbon dioxide, light energy, and water into food energy and oxygen.
Photosynthesis
_____ is a process that converts food energy and oxygen into carbon dioxide, water, and cellular energy.
Cellular respiration
_____ are organisms that consume (eat) dead matter, inorganic matter, etc. and convert those molecules into nutrients for the rest of the ecosystem.
Detritivores
An organism that consumes other consumers are called
carnivores
An organisms that consumes only producers are called
herbivores
An organism that consumes both producers and consumers are called
omnivores
Big detritivores are called
scavengers
Organisms called _____ convert organic matter into small elements and molecules that can be recycled back into the ecosystem. They don’t actually “eat” the food. They just break it into smaller components.
decomposers
The _____ states only about 10% of the energy from one trophic level is transferred to the next level
10% rule
What are the types of symbiosis
commensalism, mutalism, parasitism, predation, competition
2 species that share the same resources are active at different time of day
temporal partitioning
using different parts of habitat and common amongst plant species
spacial partitioning
differences in body shapest size
morphological partitioning
Nearly all the energy that powers an ecosystem comes from the
Sun
Equation of photosynthesis
solar energy+6H2O+6CO2=C6H12O6+6O2
Equation of Cellular Respiration
energy+6H2O+6CO2= C6H12O6 + 6O2.
plants____and_____
photosynthesize,respire
plants_____and________oxygen
produce,consume
Without photosynthesis ____
there wouldn’t be usable energy for consumers and there would be no food chains or webs
Photosynthesis produces ____ needed for heterotrophs to perform cellular respiration
oxygen gas
Cellular respiration allows animals to
produce cellular energy from food
the sequence of consumption from producers through tertiary consumers
food chain
multiple food chains intertwined in nature
food web
