Ecology

Ecological Relationships

TermDefinition
Competition The relationship between organisms in the same ecosystem fighting or competiting for limited resources, such as food, water, space, or mates.
Biodiversity The abundance of living things in a particular ecosystem.
Symbiosis/Symbiotic Relationship The relationship between at least two organisms in which at least one benefits.
Mutualism The relationship between at least two organisms in which both benefit.
Parasitism The relationship between at least two organisms in which one benefits and the other is harmed.
Commensalism The relationship between at least two organisms in which one benefits and the other is unaffected.
Predation The relationship between at least two organisms in which one hunts and kills the other for food.
Predator The organism that is hunting it's prey for food.
Prey The organism that is being hunted as food.
Adaptation A characteristic that allows an organism to survive in it's environment, such as camouflage, having sharp teeth, or being able to run fast.
Organism One individual of one species in a particular ecosystem.
Population All of the organisms of the same species in a particular ecosystem.
Community All of the differing populations of organisms living together in one ecosystem.
Ecosystem All of the living and non-living parts of a particular area.
Endangered A population of organisms whose number is so low that it is in danger of becoming extinct.
Extinct A population of organisms that was once living but is not longer living.
Carbon Cycle How carbon is cycled in the environment. Through photosynthesis & respiration.
Nitrogen Cycle How nitrogen is cycled in the environment, helping plants to grow with the help of nitrogen fixing bacteria and bacteria that aid in the denitrification process.
Keystone species a species that is vital to the environment.
Primary Succession The creation of a new ecosystem where one has never existed before. Begins with pioneer species likes lichens and mosses, which create soil/dirt
Bioshphere All of Earth's life supporting features.
Invasive species A species that is not native to the area in which it is living. This can seriously damage the ecosystem.
Phosphorous Cycle How phosphorous is cycled in the environment through weathering.
Secondary Succession The rebuilding of an ecosystem after it has been lost as a result of human activity like logging/deforestation or after a natural disaster like a tornado or fire
Pioneer Species The first species to grow and live in an new environment, like lichens and mosses, which help to create soil/dirt where there wasn't any before
Logistic Growth Curve an s-shaped curved graph where the population growth rises until it meets it's carrying capacity, at which point it stabilizes or becomes constant
Exponential Growth Curve a j-shaped graph where the population growth rises without stopping, this is a result of unlimited resources
Limiting Factors factors in the environment that limit a populations growth
Density Dependent Limiting Factors factors that limit a populations growth based on the population size. Ex: space, mates, food and water
Density Independent Limiting Factors factors that limit a population's growth that DO NOT depend on the population size, typically abiotic factors like, fires, floods, tornados, or human activity

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.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
