The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere. There are a few exceptions to this, such as ecosystems living around hydrothermal vents on the ocean floor, which derive their energy from the chemical compounds such as methane and hydrogen sulfide. In either case, the overall productivity of an ecosystem is controlled by the total energy available.
Answer:
A. to conserve soil nutrients
Explanation:
Crop rotation helps to maintain soil structure and nutrient levels. If you don't rotate crops, the soil in that field will inevitably begin to lose the nutrients plants need to grow.
Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA
