Correct answer: B). Sunlight
Corals are found near the shallow water because it needs clear water that allows the sunlight to pass through it, they are not able to survive in when the water becomes opaque.
Presence of plankton and sediment can cloud the water, which decreases the amount of sunlight that reaches the corals. Corals are found in tropical and subtropical water.
The biogeochemical cycles of carbon, nitrogen, and phosphorus carry these elements through ecosystems, cycling them among living organisms and the environment. These cycles involve processes such as photosynthesis, decomposition, and various nitrogen transformations, with organisms like marine bacteria playing key roles. This understanding is vital for maintaining Earth's ecosystems.
The biogeochemical cycles of carbon, nitrogen, and phosphorus are essential to the functioning of ecosystems, as these cycles control the movement of these substances through the biosphere. In these cycles, elements are recycled between abiotic factors of the environment (like water, air, soil, and geological formations) and biotic organisms (living creatures).
Carbon, an integral part of all organic compounds, is cycled through processes such as photosynthesis, respiration, and decomposition. The ocean is a major reservoir of carbon and plays a significant role in its cycle.
The Nitrogen Cycle is a biological process that converts nitrogen gas from the atmosphere into different nitrogen compounds that can be used by plants. These compounds are then passed along the food chain. The processes involved include nitrogen fixation, ammonification, nitrification, and denitrification.
Similarly, Phosphorus is cycled through the environment. This is an important nutrient present in nucleic acids and phospholipids and is a major component of bones. Unlike carbon and nitrogen, the phosphorus cycle does not include a gas phase, existing primarily in solid and aquatic stages.
In all these cycles, various organisms play critical roles. For instance, marine bacteria process nitrogen in the ocean, and certain bacteria in the soil can fix atmospheric nitrogen into a form that plants can use. Understanding and preserving these cycles are crucial for the health of Earth's ecosystems.
#SPJ12
B.Because the movement of energy through the biosphere follows a path similar in shape to a pyramid
C.Because decomposers form a wide base of support at the bottom of a food web similar to the base of a pyramid
D.Because food webs are usually triangular in shape
b. False
Answer:
false
Explanation:
Answer: The correct answer for the blank is-
92.
There has been total 118 elements discovered o earth out of which approximately 92 elements are naturally occurring. Other elements are produced by artificial means.
The most abundantly occurring elements are oxygen, nitrogen, carbon, hydrogen, sulfur, and phosphorous.
