Photosynthesis |
formula: CO2 + 6H2O -> C6H12O6 + 6O2. occurs in plants, and in some bacteria, wherever there is sufficient sunlight (on land, in shallow water, even inside and below the clear ice) |
|
Chemosynthesis |
formula: CO2 + 4H2S + O2 --> CH20 + 4S + 3H2O is the use of energy released by inorganic chemical reactions |
|
cellular respiration |
occurs in mitochondrion. formula: C6H12O6 + 02 --> CO2 + H20 +ATP is the process of oxidizing food molecules, like glucose, to water and carbon dioxide. |
|
Glycolysis |
the brekaown of glucose to pyruvic acid (in eukaryotes, glycolysis occurs in the cytosol. andthe remaining processes takes place un mitochondrion. |
|
locomotion |
is the movement of whole organism; movement or the ability to move from one place to another |
|
homeostasis |
means keeping things constant |
|
multicellular |
is complex organism, made up of many cells. |
|
unicellular |
consists of only a single cell |
|
metabolism |
a chemical process that occur in a living organism in order to maintain life. metabolism can be subdivided into anabolism and catabolism. |
|
anabolism |
organisms make complex molecules from simpler ones. metabolic process that builds molecules the body needs. |
|
catabolism |
metabolic process that breaks down large molecules into smaller molecules. |
|
phospholipid |
a lipid consisting of a glycerol ound to two fatty acids and a phosphate group. |
|
species |
a group of similar organism, they are able to breed together, and their offspring are fertile |
|
population |
a group individuals of the same species which live in a particular area at any one time |
|
habitat |
a place where a community lives |
|
ecosystem |
habitat + ecosystem, and ecological unit that includes all the organism living in a particular area + abiotic (non-living) factors, // size differs, from small lakes to jungles, for example. |
|
ecology |
the study of relationships between living organisms and between organisms and their environment |
|
population growth |
slows down as resource become scarce and a population near its carrying capacity |
|
carrying capacity |
the populaion of a species that can be supported in a specific area without depleting resources. |
|
ecological niche |
functional position/role of an organism in its environment what it eats, what it does, who it eats, where it lives, how much resources it uses..... |
|
environmental resistance |
the sum of environmental factors that restrict the population growth (lack of food, parasitic infections...) |
|
boom-and-bust |
population overshoots the carrying capacity after that follows quick decline, it can lead to environmental damage and lower carrying capacity permanently |
|
mutualism |
both species benefit from association. it can be facultative or obligate. obligate is often called symbiosis. (+/+) |
|
commensalism |
one species benefits and another is not affected or harmed by the association (+/0) |
|
ammensalism |
the presence of one species has a harmful effect on each other. no on benefits from the situation (0/0) |
|
allelopathy |
one species benefits py producing a chemical substance that inhibit the growth of another organisms (+/-) |
|
competition |
