The carbon cycle is affected by a variety of factors, and happens through different processes. The processes can be divided into two, which are biological processes and geological processes. The biological aspect covers the use and production of carbon by living organisms. The geological aspect covers physical processes such as volcanic eruptions, and weathering of rocks, which may result to release of carbon back to the atmosphere. However, both of these aspects can be affected by recurring events in Earth's history. One is the switching between glacial and interglacial periods, and the other one is the seasonal changes. Glacial periods can lead to lower temperatures and lower carbon levels in the atmosphere. In contrast to this, warmer interglacial periods result to higher carbon levels primarily due to an abundance of life. Seasonal changes have a similar effect that can be observed at a shorter time. Human activities such as burning of fossil fuels and deforestation may also bring changes to the carbon cycle.
Answer:
All organisms require sulfur as a macro-nutrient. (Ans. E)
Explanation:
Sulfur is necessary for all living things. It is taken up in the form of sulfate from the soil and sea water by the plants, and algae.
Sulfur is known as the essential nutrient for plant growth. Sulfur playing various important role in plants. About 90% of the sulfur is absorbed by the plants for the purpose of amino acids synthesis, known as the building blocks of proteins. Sulfur is important for the enzyme which is helping in the formation of the chlorophyll molecule. Sulfur is essential for the synthesis of oil crops.
In human body sulfur playing some essential role such as amino acid production which is converting into proteins and producing enzymes. Sulfur is important for insulin production, insulin allow the cells to use glucose as energy. Sulfur is found in most important antioxidant known as glutathione, which helping in the inhibition of oxidation of the other molecules and preventing from cell damage. Collagen provide skin strength and structure, sulfur is important for collagen synthesis as well.
The best answer should be A) because lower price means more quantity to have.
Answer:
Plants absorb water in a large amount because water is the only medium which is present in a plant for the transportation of minerals. So, the plant absorbs a lot of water even if it is lose by transpiration.
Explanation:
