Which statement explains the most realistic way to model energy flow in an ecosystem?

A food chain is most realistic because many organisms eat one type of food, and energy moves through a single pathway.
A food chain is most realistic because many organisms eat a variety of foods, and energy moves through different pathways.
A food web is most realistic because many organisms eat one type of food, and energy moves through a single pathway.
A food web is most realistic because many organisms eat a variety of foods, and energy moves through different pathways.

It is the food web goes through many fazes I was finna go

Answer from: brendasortocortez

d. A food web is most realistic because many organisms eat a variety of foods, and energy moves through different pathways.

Explanation:

In a food chain, the animals eat the animal before and not multiple animals, whereas food webs show what every organism eats and they usually eat multiple things.

Hope this helped

Answer from: Quest

assuming that your periodic table has eighteen columns, you should highlight the four elements in the third column from the left of the table.

explanation

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the $3d$ have energy higher than those in the $4 s$ orbital while lower than those of the $4 p$ orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the $4s$ orbital is therefore filled right after $3p$ orbitals and before $3 d$ orbitals.

potassium has electron configuration $[\text{ar}] 4 s^{1}$ and calcium $[\text{ar}] 4 s^{2}$ . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration $[\text{ar}] 4 s^{2} \; 3d^{1}$ and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the $ns^{2} \; (n-1) p^{1}$ and should be highlighted as well.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
