Chapter 16, Problem 12LTB
Summary Introduction
Introduction:
An ecosystem refers to a community of living species in combination with the non-living constituents of the environment. These biotic and abiotic constituents are associated together via energy flows and nutrient cycles.

Students have asked these similar questions
Plant growth is most likely to be limited by the available supply of usable: a. nitrogenb. carbonc. oxygend. phosphorus
Plant growth is limited by available nitrogen. Why is nitrogen fixation a limiting factor?
There is very little nitrogen available after fossil fuel combustion utilizes the available nitrogen.
Nitrogen must be produced by bacteria due to the inability of recycling by decomposers.
There is no nitrogen in the atmosphere; it is only found in aquatic biomes.
The stability of nitrogen gas makes it difficult to turn into nitrogen for living things.
The limiting nutrient in an ecosystem is the nutrient;
that is the most scarce nutrient that is needed for more growth to occur
that is limited however is not needed by many organisms in the system
is almost always carbon dioxide
is almost always nitrogen gas

- Plants obtain ______ by taking it up from the air. a. nitrogen c. phosphorus b. carbon d. waterarrow_forwardHow can soil erosion lead to desertification? It reduces the level of organic matter It promotes flooding that destroys vegetation It promotes salinization that destroys soil structure Which of the following is not a factor that may lead to urban sprawl? Pollution Immigration Overpopulation Which statement is NOT true about soil salinization? Soil dehydrates due to decrease in accumulation of water underground. Starts by attempting to wash the salts out of the topsoil by pumping more water. Results to the damage and killing of plants as saline water surrounds its deep roots. Which would most likely happen if too much nutrient entered a freshwater ecosystem? Algae will decrease, leaving few food resources, for fish. Nutrients would sink to the bottom, increasing soil deposition. Algae breakdown lowers dissolved oxygen, causing fish to suffocate.arrow_forwardThe practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relatiorhip, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Why would nitrogen-fixing plants be plowed under instead of harvested? * To increase water retention. O Nitrogen-fixing plants are not a food crop. To increases usable nitrogen in the soil. To decrease bacteria in the soil.arrow_forward

First, a plant without a nitrogen-fixing relationship. such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Crop rotation would allow the farmer to reduce which of the following? O Planting seeds. O Watering the fields. O The use of manufactured fertilizer. O The burning of fossil fuels by farm equipment. In the year 2000. specimens of Caulerpa taxifolia,a green alga used in tropical aquariums, were found off the coast of California.

- Human Activity Effects on Soil Quality Effects on Soil Quantityarrow_forwardAll of the following are reasons why tropical rain forests less likely to grow back as secondary growth forests after widespread deforestation (when compared to temperate forests) EXCEPT: Question 25 options: - All of the above are significant reasons why tropical rain forests may not grow back after widespread deforestation. The soil of tropical rain forests contains much less organic matter and nutrients compared to the soil of temperate forests. - The trees in tropical rain forests are largely responsible for returning water vapor back to the atmosphere through evapotranspiration, so when they are gone, the rains come less frequently. - A larger percentage of the nutrients in a tropical rain forest system are stored in the trees themselves than in temperate forests. - Almost all tropical rain forest species are wind-pollinated, which is less reliable than insect-pollination so tree reproduction is affected more by “chance.”arrow_forwardState whether the following is True or False of the process of eutrophication from the overuse of fertilizers. Group of answer choices Eutrophication often starts with stimulating algal growth [ Choose ] TRUE FALSE Eutrophication results in loss of dissolved oxygen from the process of photosynthesis [ Choose ] TRUE FALSE It is the decomposition of algae after algal blooms that lead to bacterial growth causing a loss of oxygen [ Choose ] TRUE FALSE Eutrophication is a natural process and can occur in the absence of fertilizers [ Choose ] TRUE FALSEarrow_forward
