Ecosystem process Flashcards
aerobic respiration
Chemical reaction where glucose reacts with oxygen to release energy, carbon dioxide, and water.
algae
Green unicellular or multicellular organisms that perform photosynthesis and live underwater.
anaerobic respiration
Chemical reaction that takes place without oxygen. Glucose is converted into lactic acid and energy is released.
bioaccumulation
The build up of toxic chemicals inside organisms in a food chain.
chlorophyll
Green pigment that absorbs light for use in photosynthesis.
co-exist
Plants and animals living in the same habitat at the same time.
community
The collection of the different types of organism present in an ecosystem.
consumer
Organisms that eat other organisms as food.
deficiency
A lack of minerals, that causes poor growth.
ecosystem
The name given to the interaction between plants, animals, and their habitat in a particular location.
fermentation
Chemical reaction used by microorganisms to convert glucose into ethanol, carbon dioxide, and energy.
fertiliser
Chemical containing minerals, normally applied to soil.
food chain
A diagram that shows the transfer of energy between organisms.
food web
A diagram showing a set of linked food chains.
habitat
The area in which an organism lives.
haemoglobin
The substance in blood that carries oxygen around the body.
interdependence
The way in which living organisms depend on each other to survive, grow, and reproduce.
magnesium
A mineral needed by plants for making chlorophyll.
niche
A particular place or role that an organism has in an ecosystem.
nitrates
Minerals containing nitrogen for healthy growth.
oxygen debt
Extra oxygen required after anaerobic respiration to break down lactic acid.
phosphates
Minerals containing phosphorus for healthy roots.
photosynthesis
The process plants use to make their own food, glucose. In photosynthesis, carbon dioxide and water react together to make glucose and oxygen.
plasma
The liquid part of blood, which carries carbon dioxide to the lungs where it is exhaled.
population
The number of plants or animals of the same type that live in the same area.
potassium
A mineral needed by plants for healthy leaves and flowers.
predator
An animal that eats other animals.
prey
An animal that is eaten by another animal
producer
Organism that makes its own food using photosynthesis.
stomata
Holes found on the bottom of the leaf that allow gases to diffuse in and out of the leaf.
Equation for Photosynthesis
Carbon dioxide + water —- oxygen + glucose
Equation for Aerobic respiration
glucose+oxygen——carbon dioxide + water
Equation for Anaerobic respiration
glucose— lactic acid
Equation for Fermatation
Glucose ——Ethanol + carbon dioxide
