Using the 10 percent rule, explain why there is typically smaller populations of quaternary consumers compared to primary consum
grandymaker [24]

Answer:

As we know 10% law is transfer of energy from higher trophic level to lower trophic level. So as the energy are transfer from one organism to another there is a loss of energy as that energy are utilised by the oragnism and only 10% of the total energy is transferred to the second consumer.

Explanation:

Quetinary consumer are at the higher position in the food chain so they do not get enough energy from prey they have to feed on several organism for the enegy. And also they are at the top of the food chain so they are not eaten by other animal, their life span are also more than primary consumer.

In other hand primary consumer get enough energy but they are prey for other higher tropic level.

Primary and secondary consumer are maintend in such a way by the nature thats make a ecological balance of the habitant.

The bees wing are moving very fast the best wings are much smaller than it body ?
marishachu [46]

Explanation:

It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.

Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.

Which of these is not part of insect immunity? A. enzyme activation of pathogen-killing chemicals B. activation of natural kille
Firlakuza [10]

Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.

What is enzyme activation of pathogen?

Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.

  • TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
  • The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
  • The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
  • Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.

Hence, the correct answer is option A
