Chapter 2.2 Flashcards
In population survival strategies, what letter strategist that organisms generally have high intrinsic rate of growth, relatively short life span, fast body growth, early maturation, tend to be smaller organisms, tend to do well in extreme conditions, and can compete by outgrowing other organism? Give examples.
R-strategists. Ex. many weed species, oysters, rats
In population survival strategies, what letter strategist that organisms generally have low intrinsic rate of growth, long life span, slow maturation, tend to be larger organisms, tend to do better under stable conditions, and can compete by using greater efficiency? Give examples.
K-strategists. Ex. many large mammals including humans
collection of populations of different species living and interacting in the same area.
Community
A continuing and close relationship between species.
Symbiosis
Which among the three types of symbiosis has a benefit to one species and the other is neither harmed nor helped?
Commensalism | +/0 relationship
Which among the three types of symbiosis that one species benefits (parasite) and the other is harmed (host)?
Parasitism | +/- relationship
Which among the three types of symbiosis that is beneficial to both species?
Mutualism | +/+ relationship
Pathogen / Host, Predator / Prey, Herbivore / Plant is a type of what symbiosis?
Parasitism
Male weaver birds compete to attract a mate. This is [blank] competition: a competition within the [what] species.
INTRASPECIFIC, same species
Invasive starlings will out-compete native bluebirds for nesting holes. This is [blank] competition: competition between [what] species.
INTERSPECIFIC, different
a community of populations and their physical environment interacting as an ecological unit.
Ecosystems
Rearrange the flow of energy in an ecosystem: Plants consumed by animals to obtain energy, Energy loss to the environment, Sunlight converted to usable energy by plant
Sunlight converted to useable energy by plants, Plants consumed by animals to obtain energy, Energy loss to the environment
The flow of nutrients in an ecosystem: Cycling of [guess] → occurs at the global level as well, Cycling of [what]
Nitrogen, carbon
T|F: All biotic and abiotic factors need both matter and energy.
False, living things(biotic factors)
T|F: The transfer of matter flows one-way through the biosphere and leaves the Earth. A new input of matter is continually needed.
False, the transfer of energy, input of energy
T|F: The transfer of matter is when the same atoms are use over and over again. Matter is recycled, not “lost”.
True
[guess] and [guess] are transferred between organisms, and between organisms and the abiotic environment.
Matter and energy
