Answer:

The correct answer would be C) available energy is lost from one trophic level to the next.

It is the universal law that the energy is lost when transferred from one trophic level to the next.

It is because most of the energy present at any trophic level is used by the organisms for their biological processes such as locomotion, reproduction et cetera. Due to this, most of the energy is lost as heat in the surrounding environment.

In the given food chain, the bears are present at the highest trophic level and thus they would get minimum energy.

Thus, the ecosystem can provide only a limited amount of energy to the bears due to which the ecosystem can support a limited number of bears.

A pharmacist has two vitamin-supplement powders. The first powder is 10% vitamin B1 and 30% vitamin B2. The second is 15% vitami

Basile [38]

Answer:

$560$ mg of powder 1 and $160$ mg of powder 2

Explanation:

Let "X" denotes weight of powder 1 added to the new mixture and "Y" denotes weight of powder 2 added to the new mixture

Total weight of vitamin B1 in the mixture is equal to $80$ mg

Total weight of vitamin B2 in the mixture is equal to $200$ mg

Equation 1

$0.1 X + 0.15 Y= 80$

Equation 2

$0.3 X + 0.2 Y= 200$

Let us simplify the above two equations, we will get

$10 X + 15 Y = 8000\\3X + 2Y = 2000$

$2 (10 X + 15 Y = 8000), 20X + 30 Y = 1600015(3X + 2Y = 2000), 45X +30Y = 30000\\25 X = 14000\\X = 560$

Substituting value of X in equation 2 we get

$0.3 * 560 + 0.2 Y = 200\\0.2 Y = 200 - 168\\Y = 160$
