Question:environmental science

Answers:Biotic factors refer to anything that is living in the environment, namely organisms. Abiotic factors refer to anything that is nonliving in the environment. Examples of abiotic factors include: geography of the land, water, rocks, and climate.


Answers:Biotic factors are concerned with living things like, fungi, bacteria, virus, insect pests, phytoplasma, nematodes, mycoplasma etc. Abiotic factors are non-living things like climatic (temperature, rainfall, humidity, frost etc.) and edaphic (soil, water logging, drought, salinity, alkalinity, pH etc.) factors.

Question:Describe the differences between the abiotic and biotic factors of a natural ecosystem and an artificial ecosystem

Answers:Abiotic is any factor that is not living, Biotic is a living factor. That being said, an artificial ecosystem(such as a aquarium) can be mainpulated more easily then a natural one. Abiotically you could change the temp of the water, remove lighting around the aquarium, these would mimic weather patterns in nature. Biotically you could introduce a predatory species to the aquarium, or stop or reduce feeding. To affect a natural ecosystem you would need more more power then affecting an artificial ecosytem. Artificial ecosystems are much less complex then natural ones.

Question:Describe the differences between the abiotic and biotic factors of a natural ecosystem and an artificial ecosystem

Answers: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 temperature by increasing heat loss by evaporation and convection. 6. Natural Disasters: Fire, hurricanes, typhoons, volcanic eruptions can devastate biological communities. Principle of Allocation: Each organism has a limited, finite amount of total energy that can be allocated for growth, reproducing, obtaining nutrients, escaping predators and coping with environmental changes. Species living in stable environments: Lead a good life in a small area. Species living in unstable environments: Lead a rough life over a wider range.
