Answer:
fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.
Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.
Answer:
B. Floating freely in the cytoplasm
Floods affect the environment by destroying building, creating areas of more fertile soil and speeding up the weathering of rock.
Answer: Option A,B & C
<u>Explanation:</u>
Floods obviously destroy every building on its way ruining the whole place taking away the lives of people and stock. But the flood also carries many nutrients along it’s way which creates areas of more fertile soil.
Unexpected floods enter into the holes of the rock and during winter it transforms into ice and causes crack in the rock. The flood water gushing fast normally breaks down the corners of the rock hence causing weathering of rock.
Answer:D) Decomposers break down the remains of producers and consumers
Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.
The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.
This tell us that the ultimate dead part of producers and consumers are used up in this process.
Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.
Note: The biogeochemical cycle is a pathway of movement for chemical elements.
The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem
Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.
All living and non living elements of nature play vital roles in the great biogeochemical cycle.
