Why are there usually more producers than primary consumers in a food chain?

Biology

Answer:

This is because the level of energy decreases throughout the food pyramid.

At the beginning with producers, they contain the most energy or 100%. However, once they are consumed, the consumer loses 90% of the energy. Thus, primary consumers only get 10% of the energy, secondary consumers only get 1% and so on and so forth higher.

Because of the lack of energy being passed along within the food pyramid, higher order consumers (typically carnivores) must have a lot of prey to consume, but this also means competition. Therefore, higher in the ranks, there is more competition which leads to smaller populations.

olganol [36]

The right answer is A.

The methylation profile of DNA is not obtained when DNA sequencing is performed.

Methylation is a process that can occur in DNA especially at the cytosine level. And this has a very important role in gene expression as it is part of the epigenetic expression.

Gene methylation can induce or repress gene expression depending on the localization of methylated bases.

Concerning proton movement in mitochondria and chloroplasts, the __________ have a __________ H+ concentration. Choose one: A. l

umka2103 [35]

Answer: The answer is D - Intramembrane space in mitochondria; high

Explanation:

Mitochondria is an organelle in the cell, it is known as the power House of the cell because of its role in the storage and production of energy. During electron transport chain the proton pumps generate a proton gradient which is stored in form of energy.

During proton pumping and electron transfer the electrons are passed down the chain from the matrix to the inter membrane of the mitochondria. The electrons move from higher concentration of level to lower energy level. Some of these are used to pump Hydrogen ions (H+), moving them out of the matrix into the inter membrane space.

The Intramembrane space of the mitochondria therefore has a a high concentration of Hydrogen ions (H+).

I hope this helps.
