Question:Four environmental factors are listed below. A. energy B. water C. oxygen D. minerals Which factors limit environmental carrying capacity in a land ecosystem? (1) A, only (2) B, C, and D, only (3) A, C, and D, only (4) A, B, C, and D

Answers:Of those, your teacher probably wants 4) A, B, C, and D If you had an "A, B, D" possibility, I'd put that, since oxygen by itself is not a limiting factor in terrestrial ecosystems. Where there's little oxygen, the low temperature is a far greater limiting factor (tops of high mountains, you know).

Question:pls help asap gr. 9 science answer thx

Answers:Biotic factors > living components in a forrest ecosystem > Deer, hare, fox, woodpecker, bug, tree,mushroom, grass etc. Abiotic factors > nonliving components in a forrest > sun, soil, minerals, water, temperature, weather etc.

Question:

Answers:the relationship between living aquatic organisms and their environment. The environment is determined by biotic (living) and abiotic (nonliving) factors. Biotic factors include plants and animals in or around the water. Leaves that fall into the water, and the park s beaver populations that dam up streams, are both biotic factors. http://www.discovercarolina.com/html/s05nature02a02.html http://www.umd.umich.edu/sep/students/jtomassi/jtomassi_lifeact.html

Question:

Answers:The abiotic factors are the non-living factors that make up the environment in which the organism lives. The terrestrial abiotic factors are a set of factors that impact on the distribution of organisms living on that terrestial ecosystem, I can show you some of them: - Temperature: the temp degree impacts essentially on the distribution of organisms, each organism (plant / animal) has a Temperature range within which the organism can live. - Precipitation: the volume of water precipitated on this area & the form of water (liquid, vapor, snow) effect the life of any organism living in this ecosystem. - Soil: type of soil ( clay or sandy or any other type) , rich or thin, fertile (contains sufficient minerals) or not. All these characters effect the life of a living organism. Aquatic Abiotic factors >>>>> such as - Eutrophication: if this aquatic ecosystem is rich with minerals with frequent additions of minerals to this water.this charater has an effect on the organism's life fo sure. - Light: the light is a very important character in aquatic ecosystem, becouse it decreases gradually with the increase of depth. - Salinity: the concentration of salt in an aquatic ecosystem effect the distribution of organisms - pH: the pH value off course effects the distribution of organisms. - Temprature: effects the distribution of organisms in an aquatic ecosystem as in the teresstial ecosystem.
