Answer:
In biology, biotic components can be described as the living components of an ecosystem. Abiotic components can be described as the non-living components of an ecosystem. Both, the biotic and abiotic factors are important in maintaining a stable ecosystem whether it be a terrestrial ecosystem or an aquatic ecosystem.
Some of the abiotic factors which affect the distribution of the aquatic life are:
- <em>Amount of light: </em>The area which will receive more light will result in greater biodiversity. This is because there will be more number of plants in this area of the water and more plants means that there will be more aquatic animals present to feed on these plants.
- <em>Water flow rate: </em>Some organisms in the water are sensitive to high flow rate. More diversity will be seen in areas where the water flow is stable.
- <em>Temperature: </em>Although many of the fishes are cold-blooded, yet there will be greater diversity where the temperature will be moderate.
Some of the biotic factors which affect the distribution of the aquatic life are:
- <em>Predators: </em>If there are more number of predators than the preys, then the prey diversity will have a serious threat.
- <em>Aquatic plants: </em>There will be more aquatic biodiversity in the areas where there will be more aquatic plants.
Answer:
It is the study of many things but mainly life process, interactions and adaptations. (The sucession development in the ecosystem)

My Answer: Mutations produces random changes in an organisms genetic code. Some examples of the changes are: None of the mutations may have a positive, negative nor neutral effect on the organism. A different organism may be produced. Mutations help organisms better, so that they're able to survive, if mutations do that it is more likely that the organism will survive and pass the mutated gene onto the next generation.
Hope I helped! :D
Answer: sporophyte, gametophyte, alternation of generation
Explanation:
Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.
Oxbows and loess both show similarity as they both show the constructive power of erosion. An oxbow lake starts as a curve in a river. Oxbows are formed where the river often empties into another water body. ... A loess is a sediment which is formed by the accumulation of the wind blown silt
