Carbon dioxide plays an important role in carbon cycle. Carbon dioxide is used by plants in the process of photosynthesis to make food. The food is eaten by animals to gain energy and performs cellular respiration which releases carbon dioxide back to the atmosphere. This is the process of biological carbon cycle.
In geological carbon cycle, carbon dioxide enters the ocean by precipitation and combines with elements like calcium forming a compound and becomes the component of living organisms. Carbon compounds settles in the ocean when the organisms die.
Mendel said that the factors that control a trait exist in pairs. TRUE
Answer:
In plants
Explanation:
Photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
The answer is nitrogen. It is usually regarded as a growth-<span>limiting</span> factor for <span>primary</span> <span>producers</span> such as <span>phytoplankton</span>. It is <span>usually</span> taken up in the ‘fixed’ form of ammonium. It is converted from
<span>dissolved</span> nitrogen gas in ocean surface
to a ‘fixed’ form by particular microbes. Due to <span>increasing</span> global <span>temperatures,</span>
as a result of global warming, the ocean temperatures have increased hence
oceans hold less dissolved oxygen than they used to. <span>The low</span> oxygen concentration in the oceans <span>induces</span> the loss of nitrogen from oceans through <span>increased</span> activity of micro-<span>organisms</span> that are significant in
denitrification. This rate becomes higher than that of nitrification that fixes
nitrogen in the oceans. <span> </span><span> </span>
