In Minnesota, ecologists want to restore an abandoned cow pasture into a prairie ecosystem. The soil in the abandoned pasture is homogenous with high nitrogen content and is dominated by bunch grasses that prefer high nitrogen conditions and inhibit the establishment of other native prairie plant species. The ecologists decide to introduce native pocket gophers to the prairie to facilitate the restoration. Which of the following factors is improved by adding pocket gophers to the abandoned pasture?
A. Interspecific plant interactions inhibit plant growth and establishment.
B. Colonization is limited by poor dispersing plant species.
C. Plant establishment is limited by suitable "safe" sites that are protected from weather extremes
D. Herbivory can restrict establishment of plants that are attractive to herbivores.

Answers

Answer:

The factor that is improved by adding pocket gophers to an abandoned pasture is:

B. Colonization is limited by poor dispersing plant species.

Explanation:

In ecological management, colonization describes the action by a plant or animal to establish itself in an area. When pocket gophers are added to an abandoned pasture, the area is repopulated by these rodents. By their nature, pocket gophers move some quantity of soil annually, thereby aerating the soil. Moreover, they build tunnels, which they later abandon for other species as natural habitat. They also leave some waste products to fertilize the soil, making the ecosystem alive again.

Which of the following gives you information about population density?
A
the number of births per year

B
the number of frogs in a pond

C
the number of deaths per year

D
the number of bacteria per square millimeter

Answers

Answer:

the number of births per year

The number of frogs in a pond gives you information about population density. Therefore, the correct option is B.

What is population density?

Population density is the measure of the number of individuals in a population per unit of area or volume. Option B, the number of frogs in a pond, provides a direct measure of the population size in that particular habitat. The more frogs there are in a pond, the higher the population density.

Options A and C, the number of births or deaths per year, may give some information about population growth or decline but do not provide information about density. Option D, the number of bacteria per square millimeter, may give information about population density, but this applies specifically to bacterial populations, and not necessarily to populations of other organisms.Therefore, the correct option is B.

Researchers find to imitate photosynthesis through utilizing concentrated carbon dioxide and suitable catalyzers. By this process, they were able to create fuels from solar energy by a process of artificial photosynthesis to collect high amounts of energy from the sun. Peidong Yang, a chemist at UC Berkeley, successfully developed the first photosynthetic biohybrid system (PBS) in 2015.PBS in which semiconductor it was treated as a first-generation PBS in which semiconductors and live bacteria are used to perform photosynthesis just like real leaves, absorb solar energy and formation of the chemical product occur by using water and CO2, releasing O2. This technology is termed artificial photosynthesis, and if this technology continues to improve, surely it will act as the future of energy.
