Answer: Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum.

Explanation: Photons reflected by pigments in leaves are used by leaves to carry out photosynthesis is not true as the photons are absorbed as a source of energy by the pigments to carry out the process of photosynthesis.

Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum is true as only visible light is visible to human beings.

Photons are units of light that travel from the sun to leaves in the same way that particles travel through space is not true as photons travel from the sun to leaves by radiation in the form of electromagnetic waves and do not require any medium but particles require medium to travel.

The wavelengths that make up the electromagnetic spectrum each have the same amount of energy is not true as the electromagnetic radiations have different wavelengths and thus have different energies.

$E=\frac{hc}{\lambda}$

Question:

Shkiper50 [21]

The reason that might cause a reaction that originally proceeds through the path of X to change and proceed through the path Y is the addition of a catalyst.

<h3>What is a catalyst?</h3>

A catalyst is a substance that provides an alternative path for reaction. This implies that the energy tat s required to surmount the energy hump as the reactants are converted into products have been reduced. This can be seen in the fact that the energy hump between the reactants and the products in Y is lower than that in X

Thus, we could say that the reason that might cause a reaction that originally proceeds through the path of X to change and proceed through the path Y is the addition of a catalyst. The catalyst lowers the activation energy of the reaction.

If the total amount of energy in the producer level of an ecosystem is 40,000 kilocalories, approximately how much energy is ava

Dmitry [639]

Hey there!

Answer: 400 k-cal

I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.

Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal

As we plug in this formula into our problem above, our answer would be explained below.

40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal

Answer: 400 k-cal
