Answer:
1. nutrient recycler
2. mutualist
4. parasite
Option C
Explanation:
Nutrient recycler: The bacterial decompose the dead plant and release the organic elements back to soil or air. The organic matter present in the dead plant parts is decomposed and the carbon is released into the air. Similarly, other nutrients stored in the dead plant are decomposed by the bacteria and are released into the environment so that they can enter the nutrient cycles.
Mutualist: The bacteria living on the surface of leaf obtains nutrition from it. The plant is benefited by this association since the bacteria prevents the invasion of other pathogens in the plant. An ecological interaction wherein both the species are benefited is called mutualism.
Parasite: Once the bacteria enter the leaf, it causes disease to the plant. Here, the plant is the host while the bacteria is a parasite. The plant is harmed while bacterial obtains nutrition from the plant.
The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
The process that occurs in a cell when there is not enough oxygen
is called fermentation. Fermentation occurs through the process of Anaerobic Respiration,
where instead of using oxygen, organic and inorganic molecules are used as
final electron acceptors. The by-product of this process is usually alcohol,
ethanol, or acetic acids.
<span>
Fermentation is commonly used in lactic acid (in muscles) and alcohol (beers,
whiskey) fermentation where the by-product is ethanol. Yeasts are a common
organism that uses this process, where it convert sugars into alcohols or
acetic acids.</span>
