ECOSYSTEM VOCAB

QuestionAnswer
Biodegradation The process by which microorganisms break down organic compounds through enzymatic reactions.
Producer A person who makes or supervises the creation of a work, such as a film, play, or album, or an entity that manufactures or grows something.
Decomposer An organism, such as bacteria, fungi, or invertebrates (like earthworms), that breaks down dead organic matter.
Energy Flow The one-way transfer of energy through an ecosystem.
Food Pyramid Represents the flow of energy through an ecosystem's trophic levels, with producers at the base and successive levels of consumers above.
Photosynthesis The biological process where plants, algae, and some bacteria use light energy to convert carbon dioxide and water into glucose (a sugar) and oxygen.
Primary Producer Organisms that create their own food, forming the base of a food web by converting light or chemical energy into organic matter.
Tertiary Consumer An organism that occupies a high trophic level, primarily feeding on secondary consumers.
Biotic All living or once-living components of an ecosystem, such as plants, animals, fungi, and bacteria, which interact through predation, competition, and symbiosis.
Nitrogen Cycle A biological process where nitrogen is converted between its gaseous form in the atmosphere and its usable forms in ecosystems.
Carbon Cycle The biological process where carbon atoms move between the atmosphere, oceans, land, and living organisms through processes like photosynthesis, respiration, and decomposition.
Geosphere The interconnected study of the geosphere (Earth's rocks, land, and soil) and the biosphere (life).
Hydrosphere All the water on Earth and its critical role in supporting life.
Terrestrial The study of organisms that live on land, focusing on their interactions with the land-based environment and with each other.
Biomass The total mass of living or recently dead organisms in a given area or ecosystem.
Consumer An organism that obtains energy by feeding on other organisms or organic matter, making them heterotrophs.
Decomposition The process by which complex organic matter, such as dead organisms, is broken down into simpler inorganic substances by decomposers like bacteria, fungi, and invertebrates.
Food Chain A linear sequence of organisms where energy and nutrients flow from one organism to another through consumption.
Food Web A complex network of interlocking food chains that illustrates the feeding relationships and the flow of energy and nutrients within an ecosystem.
Primary Consumer An organism that feeds directly on producers (like plants or algae), making it a herbivore.
Secondary Consumer An organism that gets its energy by eating primary consumers (herbivores).
Trophic Studies the feeding relationships in an ecosystem, specifically focusing on how energy and nutrients flow between different trophic levels.
Abiotic Studies the non-living chemical and physical factors of an ecosystem.
Water Cycle A biological process where water moves between the Earth's surface and atmosphere, involving living organisms, and is crucial for sustaining life.
Biosphere The biosphere is studied through the lens of how life interacts with and is structured within its environments, from individual organisms to global cycles.
Atmosphere The gaseous layer surrounding Earth that provides essential gases for life, such as the oxygen animals breathe and the carbon dioxide plants use for photosynthesis.
Aquatic The scientific study of aquatic organisms, their habitats, and their interactions, encompassing both freshwater (lakes, rivers, wetlands) and marine environments (oceans, coral reefs, estuaries).

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.
