Gr 8 Ecology Terms And Definitions

TermDefinition
Ecology study of how organisms interact with each other and with their environment
environment All living things and nonliving things that exist on earth
Habitat The natural home or environment of an animal, plant, or other organism.
Abiotic non living things, physical things such as , minerals, air or things measured such as temperature, hours of daylight, salt concentration
QQBiotic living, these factors are organism such as plants, animals, mushrooms, bacteria, algae
Ecosystem Ecosystem: A complex self regulating system in which living things interact with living and non living things.
Herbivores Herbivores* - An animal that eats ONLY plants.
Carnivores Carnivores* An animal that eats mostly meat
Omnivores Omnivores* An animal that eats both plants and meat.
Predators Predators* - animals that catches and feeds off of other live animals
natural ecosystem: natural ecosystem: A natural ecosystem is neither planned nor maintained by people.
artificial ecosystem artificial ecosystem -> Artificial Ecosystem is planned and maintained by people. Examples: City, Zoo, Aquarium, Farm
Scavengers Scavengers* An animal that mostly eats decaying biomass
Detritivores Detritivores* - A consumer that feeds on organic matter
Population Population* - A group of members of the same species that live in the same area.
Community Community*->populations of different species that live and interact in the same area.
Ecosystem Ecosystem* - interaction of community and surrounding abiotic components
Biome Biome* -> Large geographical region that contains similar ecosystems
Biosphere Biosphere*-> A part of our planet, including water, land and air, where life exists. Biomes combine to form this...
Biodiversity Biodiversity -> Number and range of different organisms in an area.
Toxins harmful substances that contaminate the air, water, soil, and food, potentially causing health problems for organisms.
Bioaccumulation Bioaccumulation- gradual build-up of chemicals in an organism’s body
Photosynthesis Photosynthesis - The process plants use to produce carbohydrates from carbon dioxide, water, and sunlight.
Extirpated Extirpated species that no longer exist in a particular region but still occurs elsewhere
Amphibious Amphibious - born in water, breathing with gills but can live on land or in water
Autotroph Autotroph- Organisms that can make their own food from basic nutrients and sunlight. Examples:green plant,algae
Heterotroph Heterotroph - organisms that must feed on other organisms to obtain energy
Carrying capacity Carrying capacity -> maximum number of individuals that an ecosystem can support without reducing its ability to support future generations of the same species
Commensalism Commensalism - type of symbiosis in which one species benefits from a relationship without helping or harming the other species.
mutualism mutualism A type of symbiosis in which both species benefit from the symbiotic partnership.
symbiosis symbiosis - Close interaction between two different species in which members of one species lives in on or near members of another species
terrestrial terrestrial - land-based animal
FOOD WEBS FOOD WEBS - A pictorial representation of the feeding relationships among organisms in an ecosystem.
Food chains od chains show two important things: A step-by-step sequence of who eats whom in an ecosystem. The one-way flow of energy from the producer to the top level consumer.
Respiration Respiration - the operation in which organisms within a specified ecosystem use the process to convert organic carbon to carbon dioxide.

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.
