Ecological Principles
The study of the relationship between an organism and its environment
Ecology
Wetlands are ____ the of nature
Kidneys or Filter
This provides a habitat to thousands of species of wildlife and insects
Forests
Areas that are semi- arid, that get less than 35 inches of precipitation annually, typically support the development of grasslands
Grasslands
Lightly saltly freshwater. Found in non-tidal marshes
brackish
The assemblage of different populations of flora and fauna species in an area
Community
In comparison to the tundra, the taiga receives more of this.
Precipitation
An essential process for the regulation of the climate and maintaining livable conditions within the earth’s atmosphere.
photosynthesis
In tropical areas, most grasslands are known as this
Savannahs
This is what soils that are either permanently or temporarily flooded are called
hydric soils
While bees feed off the pollen and nectar of flowers, they transfer pollen, which is attached to their legs, to other flowers to begin the pollination process which enables the plant to reproduce. This is an example of what type of relationship?
Mutualism
Plants known for colorchanging leaves that drop in the fall as preparation for dormancy during winter
Deciduous trees
This region has all four seasons
Temperate
This is used primarily to control weeds and aerate the soil
Tillage
The two main threats to wetlands
conversion and degradation
Is the exchange or conversion of nutrients from one form to another through biological and chemical processes
Nutrient Cycling
The remaining one percent of freshwater is found in these areas on earth
Ponds and lakes, streams and rivers and wetlands such as marshes and bogs
This became the most significant industry in the new world thanks to new settlers
Loggers
This type of grassland occurs in mountainous regions, high altitudes where trees are unable to thrive
Montane grasslands
Wetlands do this for/to groundwater
Recharge
Usually begins with colonization of lichens, such as fungi, algae and cyanobacteria or when rock is exposed from a geological or natural disturbance
Primary Succession
The three major types of habitat loss
habitat fragmentation, habitat degradation and habitat destruction
This Act of 1976 helped undo damage affecting natural areas
The National Forest Management Act
This is an important practice used by producers and range management. Crops and animals are moved around to prevent nutrient loss in the soil.
rotational grazing
These animals completely destroy marshes and river banks, they cause erosion and bring many parasites and pathogens to an ecosystem harming other mammalian populations in the wetland
