lesson 2- First part

ecosystem

basic unit of the scientific study of nature

biotic

living organisms

abiotic

non living organisms

freshwaters

cover 1.8% of earth surface, lots of living things,

marine

covery 75% like deep ocean etc

phytoplankton

small photosynthetic organisms that performs 40% of all photosynthesis on the earth

terrestrial

broad categories called biomes and know for being divers

biomes

large scale community of organisms primarily on land

macro

larger systems such as forest or lake

micro

experimental setups in the field of laboratory

producers (autotrophs)

make their own food using sunlight

consumers

need to eat food that autotrophs produced

decomposers

break down the dead and waste into nutrients

topographic factor

height, weight, steepness

topographic factors

also called indirect factors

edaphic factor

includes all the physical, chemical, and biological properties of soil

climatic factors

about weather and climate

abiotic components

physical and chemical factor that act on living organisms

abiotic factor

also known as ecologically factor

biogeochemical cycles

flow of elements and compound

water (hydrologic cycle) cycle

movement of water between on earth, underground and atmosphere

evaporation

primary pathway that the wayer moves from the liquid state back into the water vapor

transpiration

uptake of the water from the roots, transfer of water from plant tissues, and release of vapor by leaves

condensation

water vapor (gas) change to liquid water when it comes to contact to colder surface to form water droplets

precipitation

the primary connection in the water cycle that provides water from the atmosphere back to the earth

run offs

precipitation that did not get absorbed in the soil noir evaporate.
