Fusarium - Fusarium is a large genus of filamentous fungi widely distributed in soil and in association with plants. Most species are harmless saprobes and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal..

Ecology - Ecology, or ecological science, is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment. See also: Plants & Animals Ecology Research Biology Nature Earth & Climate Ecology Environmental Issues Earth Science The environment of an organism includes both physical properties, which can be described as the sum of local abiotic factors such as insolation (sunlight), climate, and geology, as well as the other organisms that share its habitat. Ecology is usually considered a branch of biology, the general science that studies living organisms. Organisms can be studied at many different levels, from proteins and nucleic acids (in biochemistry and molecular biology), to cells (in cellular biology), to individuals (in botany, zoology, and other similar disciplines), and finally at the level of populations, communities, and ecosystems, to the biosphere as a whole; t....

Climate And Habitat Diversity Affect Variety Of Animal Species In Spai.. - ScienceDaily (Mar. 28, 2009) — The Iberian Peninsula is one of the richest regions of Europe in terms of animal biodiversity. In this context, Spanish researchers have shown that the variation in terrestrial vertebrate diversity in Spain is influenced above all by climate. In addition to habitat diversity, the study concludes that, when all other factors are taken into consideration, this wealth is higher in the north (Pyrenees) and the south (Straits of Gibraltar), and is relatively less in the centre of the peninsula.

Researchers from the Univer....

Evidence Of 'Rain-making' Bacteria Discovered In Atmosphere And Snow - ScienceDaily (Feb. 29, 2008) — Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. These biological particles could factor heavily into the precipitation cycle, affecting climate, agricultural productivity and even global warming. Christner and his colleagues published their results on Feb 29 in the journal Science.

This is important because the formation of ice in clouds is required for snow and most rainfall. Dust and soot particles can serve as ice nuclei, bu....

Plankton - Plankton are drifting organisms that inhabit the water column of oceans, seas, and bodies of fresh water. See also: Plants & Animals Marine Biology Ecology Research Drought Earth & Climate Water Ecology Ecosystems Plankton abundance and distribution are strongly dependent on factors such as ambient nutrients concentrations, the physical state of the water column, and the abundance of other plankton. Plankton can be divided into three functional groups: phytoplankton, zooplankton and bacterioplankton. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis. Among the more important groups are the diatoms, cyanobacteria and dinoflagellates. Zooplankton are small protozoans or metazoans (e.g. crustaceans and other animals) that feed on other plankton. Some of the eggs and larvae of larger animals, such as fish, crustaceans, and annelids, are included here. Bacterioplankton are bacteria and arc....

  factory farm.wmv   Factory Farming and the Human Illness. The link between our meat and food borne illness/disease. This is a presentation for ENG Composition class. This will describe the factors that are responsible for animal to human sickness. The living conditions that Factory farm animals are forced to live in are affecting the human population. We are getting sick through consuming sick meat and this is affecting our wellbeing. We should not be getting sick from what we eat. Sorry I was kinda nervous and say 'um' alot!

Question : abiotic ecosystem biotic ecosystem

Answer : Biosphere: Portion of the earth inhabited by life: sum of all ecosystems. This area is a relatively thin layer of seas, lakes, streams, land to soil depth of a few meters, and atmosphere to an altitude of a few kilometers. Organisms in the biosphere are acted upon by abiotic factors (non-living). 1. Temperature: affects metabolism, range is between 0 degrees and 50 degrees centigrade. 2. Water: adaptations for water balance and conservation help determine a species' habitat range. 3. Light: Solar energy drives nearly all ecosystems. Availability of light can determine habitat. Aquatic environments, water selectively reflects and absorbs certain wavelengths; therefore, most photosynthesis occurs near the surface of the water. Animal and plant behavior is often sensitive to photoperiods. 4. Soil: Physical structure, pH, and mineral composition of soil limit distribution of plants and hence animals that feed on them. 5. Wind: amplifies the effects on ..

Question : examples of Biotic Factors (living organisms) - animals, plants, etc. examples of Abiotic Facotrs (non-living organisms) - weather, sun, soil, rocks, etc.

Answer : biotic: filter feeders that eat the algae, such as coral abiotic: water currents, fertilizer run-off (excessive amts. can be detrimental)

Question : This is for my science assignment im just really confused on this one part and too get an A I need to nail this question =)

Answer : biotic factors are living things that affect the envirment and in a rainforest it may be the trees, animals, funguses, etc any living thing and an abiotic factor would be non living things such as consatnt rainfall (water) or rocks
