|
Population |
has only one type of species of organisms |
|
|
Community |
has muiltple type of species of organisms |
|
|
Ecosystem |
the aboitic and biotic factors in one area |
|
|
Biomes |
type of ecosystem that is characterized by biome factors |
|
|
Biosphere Hydrosphere Atmosphere Lithosphere Anthrosphere |
organisms water gases rocks and minerals anything affected by humans |
|
|
flow of energy |
process of photosynthesis the sun is a source of energy for plants and other organisms |
|
|
Cycling of Matter |
Decomposing animal droppings the process of recycling matter and using it again for energy
|
|
|
Random distribution |
plants occur at random spots around the area |
|
|
Clumped distribution |
plants all clump together in one spot around that area Reason: due to limited food sources |
|
|
Uniform distribution |
plants all equally distributed throughout the area Reason: no competition |
|
|
Mutualism |
both organisms benefit |
|
|
Commensalism |
One organism benefits, the other is not affected |
|
|
amensalism |
one organism harmed, the other not affected |
|
|
parasitism |
one benefit, the other slowly dies |
|
|
interspecific competition |
both species are negatively affected |
|
|
Atmospheric Reservoir |
elements in gaseous forms cycling quickley |
|
|
Sedimentary Reservoir |
elements found in lithosphere (rocks and minerals), cycling slowly |
|
|
Secondary Plant Compound |
includes alkaloids, terpenes, and phenolics which all support the plant in varies ways |
|
|
Primary Plant Compound |
compounds formed as part of the normal anabolic and catabolic processes Assimilation Respirtation transport DNA & RNA, amino acid, chlorophyll, and starch |
|
|
Secondary Consumer |
eat primary consumers (Herbivors) |
|
|
Meristems |
cell division occurs in plant: Apical- tip of plant Lateral-increase diameter (vascular and cork cambium) Accessory-found in various parts of plants |
|
|
Alkaloids |
contain nitrogen derived from amino acids can be posioinos to animals |
|
|
Terpenes |
Volatile oils Resins Sterols made up of C5H8 |
|
|
Phenolics |
has 6 carbon ringed linked to oxygen flavonoids and tannis contains ligin (makes wood hard) |
|
|
Size of plant cells |
biggest: secondary cell wall smallest: ribosomes |
|
|
Procambium produces... Protoderm produces... Ground meristem produces...
|
xylem and phloem epidermis pith and cortex |
|
|
Factors that determine plant communities |
climate: amount of sunlight soil: inorganic or organic topography: elevation levels Biota: species of plants in area physical factors: fire, flood |
|
|
Tundra |
permaforst: permentaly frozen soil, hard for roots to grow short growing season short vegetation low rain
|
|
|
Taiga |
evergreen dominate heavy snowfall large vegetation not variety |
|
|
Temperate Decidous forest |
greater variety of vegetation vernal pools: temporary pools dry up in summer, great reproduction site for amphebians more layering and structure in plants Ground layer (plants grows below forbs) Perennial forbs (grow close to forest floor)
|
|
|
Prairie |
grasses dominate vegetation tallgrass, shortgrass, mixed prairie low structural diversity |
|
|
Desert |
less than 10 inches of rain rain shadows xerophytes grow low density vegetation
|
|
|
Mountain and Coastal forest |
big trees mild temperatures fog is source of moisture epiphytes (live on other plants) |
|
|
Tropical Rain Forest |
more than 100 inches of rain high diversity high structural development high temperatures buttresses (help hold large trees) |
