|
Greenhouse Gases |
1% of the air consists of water vapor, carbon dioxide, and methane. |
|
|
|
Stratosphere |
The next layer, reaching from 17 to 50 kilometers above the surface. |
next layer |
|
|
Hydrosphere |
Consists of all of the water on or near the earths surface. |
|
|
|
Geosphere |
Consists of the earths intesely hot core a thick mantle composed mostly of rock, and a thin outer crust. |
|
|
|
Biosphere |
Consists of the parts of the atmosphere, hydrosphere, and geosphere where life is found |
|
|
|
Greenhouse Effect |
Without this process, the earth would be too cold to support the forms of life we find here today. |
|
|
|
Community |
Populations of different species living in a particular place and potentially interacting with each other. |

An individual living being |
|
|
|

|
|
Trophic Level |
Feeding level. |
|
|
|
Producers (autotrophs) |
Self feeders make the nutrients they need from compounds and energy obtained from their environment. |
Self |
|
|
Consumers or Heterotrophs (other feeders) |
That cannot produce the nutrients they need through photosynthesis or other processes. |
|
|
|
Primary consumers or herbivores (plant eaters) |
Several types- Are animals that eat mostly green plants.
|
herbivores |
|
|
Carnivores (meat eaters) |
Animals that eat on the flesh of other animals. |
|
|
|
Consumers |
That feed on the flesh of herbivores. |
|
|
|
Tertiary |
Are other carnivores such as tigers, hawks, and killer whales (orcas) |
orcas |
|
|
Decomposers |
Are consumers that in the process of obtaining their own nutrients, release nutrients from the wastes or remains of plants and animals and then return those nutrients to the soil, water, and air for reuse by producers. |
Consumers |
|
|
Omnivores |
Such as pigs, rats, and humans eat plants and other animals. |
|
|
|
Detritus Feeders or Detritvores |
Feed on the wastes or dead bodies of other organisms these wastes are called detritus. (means debris) |
debris |
|
|
Aerobic respiration |
Uses oxygen to convert glucose back into carbon dioxide and water. |
oxygen |
|
|
Food Chain |
A sequence of organisms, each of which serves as a source of nutrients or energy for the next |
|
|
|
Food Web |
Organisms in most ecosystems form a complex network of interconnected food chains. |
network |
|
|
Biomass |
Organic matter produced by plants and other photosynthetic producers |
matter |
|
|
Payramid of energy flow |
Energy loss for a simple food chain, assuming a 90% energy loss with each transfer |
|
|
|
Gross primary productivity |
Is rate at which an ecosystems producers convert solar energy into chemical energy in the form biomass found in their tissues. |
rate |
|
|
Net Primary Productivity |
Is the rate at which producers use photosynthesis to produce and store chemical energy minus the rate at which they use some of this stored chemical energy through aerobic respiration. |
producers, photosynthesis, produce |
|
|
Biogeochemical cycle |
Natural processes that recycle nutrients in various chemical forms from the nonliving environment to living organisms and then back to the nonliving environment. |
recycle chemical |
|
|
Hydrologic cycle |
Biogeochemical cycle that collects, purifies, and distributes the earths fixed supply of water from the environment to living organisms and then back to the environment. |
water |
|
|
Nitrogen cycle |
Cyclic movement of nitrogen in different chemical forms from the environment to organisms and then back to the environment. |
nitrogen |
|
|
Phosphorus Cycle |
Cyclic movement of phosphorus in different chemical forms from the environment to organisms and then back to the environment. |
phosphorus |
|
|
Sulfur Cycle |
Cyclic movement of sulfur in various chemical forms from the environment to organisms and then back into the environment. |
sulfur |
