Would you be likely to find a food chain containing 10 links? Why or why not?

1 answer:

5 0

It would be highly unlikely to discover a food chain containing 10 links.
This is mainly due to the loss of energy that occurs with transitions through the links in the chain. Almost 90 percent of the energy obtained at one trophic level is lost when being transmitted to the other trophic level ( link in the food chain).
This means that the 10th link in the chain would get so little energy consuming the 9th level organism that it wouldn't be enough to survive.
The 2nd link gets only 10% of the initial energy absorbed by the 1st link in the chain. If the chain is 10 links long, you would lose 90% with each link, leaving next to nothing for the last few links.

Answer:

Medullary hormones: the epineprhin and the norepineprhin. Five different effects that these hormones produce are: increase heart rate, produce cardiac muscle contraction, elevate blood preasure, increase breathing, dicrease digestive activity, increase metabolic rate.
The most important mineralocorticoid secreted by the adrenal cortex: aldosterone.
Actions of the aldosterone: 1. Conserves sodioum ions and water in kidneys. 2. Excrete potasium ions 3. Conserves H2O.

Explanation:

The epineprhin and norepineprhin are the most important medullary hormons. They are so important because of the functions that they have. They are responsable for the increase of heart rate and if it´s movement, along with digestive and metabolic activity.

Thanks to the aldosterone which is the most important secreted minaralocoricoid, kidneys conserve water and sodium and eliminate posatium.
