Biotic: Living components; the biota is all organisms. Example- Abiotic factors may have indirect effect on organisms via biotic factors. Higher precipitation may impact kangaroo distribution in Australia (lower the better)‚ or climate may influence through biotic factors such as pathogens‚ parasites‚ competitors

industries through the release of chlorofluorocarbons‚ carbon dioxide and many other air pollutants (Haldar). The gasses trap heat energy from the sun causing the gradual increase in temperatures. Global warming has had negative impacts on many ecosystems around the world among them droughts‚ unpredictable weather patterns‚ sea level rises and retreating of the major ice sheets due to melting. Global warming has had an effect even on the arctic tundra. Most researchers agree that human activity is

Estuaries are unique‚ dynamic transition zones‚ between the watershed and the world ocean system. In this paper I will try to discuss the abiotic and biotic characteristics of the San Francisco Estuary and how they are important to the diversity and productivity of the organisms in the estuary. Reviewing the population growth and how it affects the estuary. The behavior of humans that affects the

Coral reefs are one of the most biologically diverse ecosystems on earth. They are made up not only of hard and soft corals‚ but also sponges‚ crustaceans‚ mollusks‚ fish‚ sea turtles‚ sharks‚ dolphins and much more. Reef systems serve as barriers protecting many coastal populations and developments from storm damage; they support commercial fisheries; they serve as major tourist attractions; and they hold the possibility of unimagined medicinal compounds in the diverse life forms within them There

This biome can be found in Alaska‚ Canada‚ as well as many places more. The geography of the Taiga has poor soil‚ tall trees‚ and is followed by the Tundra as well as the Permanent Ice caps. This terrestrial biome has both abiotic and biotic factors that can sustain an ecosystem. Sense the Taiga is typically near mountains‚ it is prone to natural disaster. Natural Disaster The Taiga‚ due to its geography‚ may not experience wild fires‚ or tornadoes. However‚ the Taiga may experience natural disasters

carried or transferred in some way from one plant to another. This can be done in two ways: biotic pollination and abiotic pollination. Biotic pollination is a process where an insect or animal transfers the pollen from one plant to another. In abiotic pollination‚ the pollen travels by either wind or water. An estimated 80% of pollination is biotic with the remaining 20% as abiotic pollination. The biotic pollination is done entirely unintentionally with insects usually going from one plant to another

After completing this training‚ the participant should know the basic biotic and abiotic components of watersheds‚ the basic natural processes and interrelationships occurring in watersheds‚ and how watershed structure and functions may vary in time and space. Some background in the life sciences is helpful for comprehending this
