Ecosystems Flashcards
Order of size in leaves
Leaf Leaf tissue Mesophyll cell Chloroplast Grana Chlorophyll
Photosynthesis process
Chlorophasts contains grana which contains chlorophyll and absorbs light energy to create glucose.
Or scientific equation
6Carbon Dioxide + water = 6glucose(c6h1206) + 6 oxygen + 6water
What light do plants absorb?
Any light on the visible light spectrum but preferably red and blue right and they reflect green light.
Producers / autotroph
At the base of the food chain and doesn’t rely on other organisms for food. Plants use photosynthesis to create food.
Metabolism
Chemical equations that occur when an organism uses energy to grow and repair cells
Cellular Respiraiton
When oxygen is used to move glucose and atp around the organism
Aerobic respiration
The chemical breakdown of food saving oxygen. The reactions need enzymes, occurs in all body cells and releases energy.
Glycolysis
Process by which glucose is converted into a simple form, during which energy is released.
Cytosol
The fluid found inside cells.
Kerbs cycle
Part of the aerobic respiration process in which carbon dioxide and ATP are produced.
Electron transport : chain reaction
Part of the aerobic respiration process.
Mitochondria
Small rod shaped organelles that supply energy to other parts of the cell. They are usually too small to be seen with light microscopes. Singular form is mitochondrion.
Anaerobic respiration
The chemical breakdown of food without oxygen. The reaction needs enzymes, occurs in cells and realises less energy than aerobic respiration.
Lactic acid
The product of anaerobic respiration in animals also known as lactate.
Ethanol
An end prodyct of anaerobic respiration in plants, a form of alcohol
Obligate anaerobes
Organisms that can respire only anaerobically, when there is oxygen.
Species
A group of living organisms capable of interbreeding with each other but not with members of other species.
Population
A group of individuals of the same species living in the same area at a particular time
Community
More than one populations living in the same area at a particular time
Ecosystem
Communities of organisms that interact with each other and their environment
Producers
Organism at the base of the food chain that does not need to feed on other organisms; also known as an autotroph.
Decomposers
Organisms that breaks down organic matter into inorganic materials
Heterotrophs
Consumer
Herbivore
Animal that eats plants only
Primary consumers
The first consumer in a food chain; aka first-order consumer.
Detritivores
Animals that feeds on and breaks down dead plant or animal matter.
Ecological niche
The position of a species or population in its ecosystem in relation to each other.
Competition
The struggle among organisms for food, territory and other factors.
Parasitism
Mutualism
Commensalism
Where a parasite lives in/on the host and the parasite has the benefits but the host is affected negatively.
Relationship between two different organisms in which both benefit
Relationship between organisms where one benefits and the other is unaffected
Interspecific competition
Intraspecific completion
Competition between organisms of same species
Same as above but different species
Symbiotic relationship
Very close relationship between two organisms of different species. It may benefit or harm one of the partners.
Carrying Capacity
The maximum amount of an organism’s population in an ecosystem
(X)iticdes
Something that kills (x)
Bioaccumulation
Magnification of concentrations of a substance such as a nonbiodegradable pesticide along the food chain; also known as biological magnification
