Module 9 - Ecological Factors Flashcards
the application of science and engineering principles to improve the environment (air, water, and/or land resources), to provide healthful water, air, and land for human habitation and for other organisms, and to remediate polluted sites
environmental engineering
primary job of environmental engineers
conserve and preserve the ecology and environment
includes physical, chemical and biological components
environment (surrounding)
When a component surrounding an organism affects the life of an organism, it becomes a _______. All such factors together are called ___________.
factor, environmental factors or ecological factors
Environmental factors can be classified into _______ and ______ which make the environment of an organism.
living (biotic), non-living (abiotic)
Four Classes of Ecological Factors
- climatic factors
- edaphic factors
- topographic factors
- biotic factors
one of the important natural factors controlling the plant life
climate
This ecological factor includes light, temperature, water, wind, and fire.
climatic factors
Climatic Factors
light, temperature, water, wind, fire
a well-known factor needed for the basic physiological processes of plants, such as photosynthesis, transpiration, seed germination and flowering
light
portion of the sunlight which can be resolved by the human eye
visible light
max rate of photosynthesis
at blue (400 - 500 nm) and red (600 - 700 nm)
this wavelength of spectrum is less strongly absorbed by plants
green (500 - 600 nm)
The visible part of light is made-up of wavelength from ______.
violet to red (400 nm to 700 nm)
affects many animals since light and dark often signals when to eat, sleep, hunt, migrate, or reproduce
light pollution
