Question

47. Materials in sedimentary nutrient cycles: a. pass through both a solid and a gaseous phase b. are never present as gases in the ecosystem c. are present as liquids in the earth but as gases in the atmosphere d. involve all of the above 48. Two species in one habitat can coexist when they: a. differ in their use of resources b. use the same resource in different ways c. use the same resource at different times d. all of the above e. none of the above 49. A situation in which birth rate equals the death rate is called: a. zero population growth b. geometric growth c. exponential growth d. saturation 50. The greatest concentration of nitrogen on Earth is found in: a. the atmosphere b. soil minerals c. living organisms d. fossil fuels

Answer 1

Solutun we are going ae disuess about topus a partuuler eylic process of a again back & environment gaseous cycle and sedimentary There are Hello, Tode day related to tology. 97. The nutrient wyle is a nutrient from environment to different stages and nutrient cyde elements that follow gaseous cycle ocand elements that follow sedimentary cyle are te Caluúum Phosphorus ete. on these options, the correct option about Sedimentary Nutrient epile is option (b). 0 are carbon, carbon, nitrogen, ete Oxygena

Because in in cycle om sedimentary sedimentary, nutrient role the elements never present as gases in environment like the elements gaseous nutrient nutrient cycle the elements will mover from land to the water and become Sedonant. And ther major reservous are sål and rocks. other options are wrong. Because options about gaseous so option ion (b) is correct Because other are nutrient wyle

can two species different ways ways. They of differ in their uso 98. Actualy in one habitat wexist in different can wexist in the use resources And they differ resources. And And thed can use the same resourier at different times. These all them to avoid intra ints a competition So (d) all the above is correct. they speific of option (d, O

eqq. The situation where both rate equals to death rate is called 200 population growth So option (as is correct. on this situation, no That's it's called as population growth phase 1. And in this phase , bath and death rate are stable other option are omurs. population growth Lero why are wrong.

growth rate یا (5) om ex al ohn Geometrie growth, th, the rate doesn't change so option (b) w were exponential growth, the birth rate is more than the death hate. So option (e) is w wrong. on saturation, no both or death caurs. So option ashong Therefore option (a) zero population growth is correct. 0 is

50 The the atmos of seen as Na And about 80% of Nitrogen not used the by Cria they ase grealest concentration of Nitrogen frund atmosphere om atmosphere, the mit nitrogon is seen in atmosphere o And this nitigin directly organisms nitrogen as nitrite , intrate amanda option (a) the atmosphere is current are usong, because only a small postion of nitregen ms. And large of nitrogen is present atmosphere Therefore option (a) is correct ete. o So s other options ins are is obtained by organisa amount of present in the pr t
