APES 3-2, 5-2 Quiz 2.2

ecology

the science that focuses on how organisms interacts w one another n their nonliving physical environemnt of matter and energy

ecologists study the 5 levels of matter….

biosphere, ecosystems, communities, populations, and organisms

living components

animals, plants, microbes

nonliving components

water, air, nutritients, rocks, heat, and solar energy

producers

organisms like green plants that make nutritients that they need from compounds and energy gathered from their environment through the process of photosynthesis

Photosynthesis

where organisms capture solar energy and combine it CO2 and O2 to produce glucose (carbohydrates)

Photosynthesis equation

6CO2 + 6O2 + solar energy —> C6H12O6 + 6O2

what is geothermal energy used for

Producer bacteria live in dark and extremely hot water around fissures on the ocean floor. Their source of energy is the earths interior OR geothermal energy. they are an excdeption to solar energy.

Decomposers

Bacteria, fungi, molds and mushroom

Detritivores

worms, soil insects, hyenas, vultures

aerobic respiration

uses oxygen to convert glucose and other chemical compounds back into CO2 and H2O

aerobic respiration equation

C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy

Anaerobic respiration/fermentation

products of this process are methane gas, ethyl alchohol, acetic acid, and hydrogen sulfide

NOTE THAT…

photosynthesis is for PLANTS ONLY, while aerobic and anaerobic respiration are for organisims

life on land is supported by…

15 CM of topsoil/ the O horizon
