Answer:
C
Explanation:
Ash from the fire helps restore nutrients
Fires clear out the brush along the ground level before they reach the trees, hence clearing the way to prevent larger fires
Eucalyptus and pine only feed after a fire event when the soil is rich
Therefore the odd one out is C
During protein synthesis the cell uses information from messenger RNA
Answer:
The answer is option B. autotrophs
Explanation:
Decomposers release nutrients like nitrogen and carbon dioxide as well as water when they feed on dead plants and animals. Decomposers include fungi, bacteria and earthworms.
These nutrients are released into air, soil and water and serve as nutrients for autotrophs. Autotrophs produce their own food from sunlight energy, water and carbon dioxide. Example include green plants; which by the process of photosynthesis produce their own food using carbon dioxide and soil nutrients.
The lake's pH has become acidic; in 1989, it was 6.7; by 1996, it had dropped to 5.1. This shows that the increase in the acidity which has several bad impacts on the lake water ecosystem and its community.
<h3>What happens when the freshwater becomes acidic?</h3>
The freshwater ecosystem differs from the oceanic saltwater ecosystem in that freshwater contains phytoplankton, edible fish, and so on. The fresh water has a normal pH, but the pH decreases and induces acidity when the water is polluted with different chemicals, such as nitrogen oxide, sulfur dioxide, etc.
When acid rain happens due to man-made pollution, this further adds acidity to the fresh water, and as a result, the species that live in the lake are not able to live and breathe properly due to a lack of oxygen. The acidity in the table increased year after year from 1989 to 1996.
Hence, the acidity of the lake increased and the pH decreased in these years, from 1989 to 1996.
