population ecology

TermDefinitionhint/example
carrying capacity the population of any species that a specific environment can 'handle' without negatively affecting that population, but at the same time, showing no population growth
competition two or more populations needing the same resource, but there is not enough of that resource to equally sustain each population to compete for light, water, oxygen, space, etc...
density-dependent limiting factors those factors that negatively affect the growth of a population and have more effect the larger the population light, water, nitrates, oxygen, etc...
density-independent limiting factors those factors that negatively affect the growth of a population, but affect populations equally regardless of their population size hurricane, tornado, drought, flood, etc....
ecologist a person who studies the interactions of living (biotic) and nonliving (abiotic) of any ecosytem
exponential growth the positive growth of a population that occurs when the population increases by a repeat factor occurs when every generation doubles in size
limiting factors those environmental factors that negatively affect the population growth of any species water, light, nitrates, oxygen, space, etc...
logistic growth the pattern of population that occurs when carrying capacity is reached after rapid (exponential) growth occurs
parasitism when one organism (the parasite) relies upon an different organism for a life need while harming that organism tapeworms, mosquitos, ticks and leeches are examples
population a number of organisms belonging to the same species that live in a defined area
predation when one organisms consumes (eats) another organisms for survival wolves prey on deer deer prey on grass

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.
