Answer: Photosynthetic organisms take light energy and use it to make their own "food". In this process they use carbon dioxide and light to make sugars and oxygen. This is great for other animals that utilize this oxygen and eat the plants for food.
HOPE THIS HELPS
Photosynthesis is the source of energy in the ecosystem. Without this energy source, there will be no food available to predators such as wolf or
tiger.
In the ecosystem, energy is transferred along the food chain. The food chain shows the feeding relationships among living organisms in the ecosystem.
The green plants are the primary producers. They are able to trap energy directly from the sun and make their own food through the process of photosynthesis.
It is this energy from the food that they make through photosynthesis that is passed along the food chain as herbivores eat green plants and are in turn eaten by the predators.
Also, green plants produce oxygen during photosynthesis which is taken in by animals such as wolf or tiger and is used in the breakdown of complex food materials.

Answer:
[tex]16.1\times 10^3\ \text{g}[/tex]
[tex]16.1\times 10^{6}\ \text{mg}[/tex]
[tex]16.1\times 10^{9}\ \mu\text{g}[/tex]
Explanation:
Mass of dog = [tex]16.1\ \text{kg}[/tex]
[tex]1\ \text{kg}=10^{3}\ \text{g}[/tex]
[tex]1\ \text{kg}=10^{6}\ \text{mg}[/tex]

So,
[tex]16.1\ \text{kg}=16.1\times 10^3\ \text{g}[/tex]
[tex]16.1\ \text{kg}=16.1\times 10^{6}\ \text{mg}[/tex]
[tex]16.1\ \text{kg}=16.1\times 10^{9}\ \mu\text{g}[/tex]
Mass of the dog in the other units is [tex]16.1\times 10^3\ \text{g}[/tex], [tex]16.1\times 10^{6}\ \text{mg}[/tex] and [tex]16.1\times 10^{9}\ \mu\text{g}[/tex].

Breathing air that contains 4.0% by volume CO2 over time causes rapid breathing, throbbing headache, and nausea, among other symptoms. what is the concentration of co2 in such air in terms of mol percentage
Answer:
1 mole of any ideal gas occupies the same volume as one mole of any other ideal gas under the same conditions of temperature and pressure.So 1 L CO2 has same number of moles as 1 L O2 and 1 L N2 etc.This means that, assuming all the gases in air are ideal gases, if CO2 is 4.0 % by volume then it is also 4.0 % by moles, because a volume of each gas has the same number of moles.

A nonmetal in the third period that should have chemical properties similar to oxygen.
Answer:
Sulfur
Explanation:
A non-metal in the third period that should have chemical properties similar to oxygen is sulfur.
This is because elements in the same group/family have similar chemical properties.
Chemical properties is predicated on the number of valence electrons within an atom. The number of valence electrons is the number of outermost shell electrons within an atom. Elements combines with one another using these valence shell electrons. Since sulfur is in the third period and the same vertical group as oxygen, they have similar chemical properties.1.

Fe2O3 is 2 parts Iron 3 parts Oxygen.
Assuming the molecular weights of both are equivalent (ideal elemental law), it is a 2:3 ratio, or 2/5 of the total.
2/5 of 100 is 40, so the answer is
40 grams
What is the percent composition of oxygen in
beryllium nitrate, Be(NO3)2?
The percent composition of oxygen in beryllium nitrate, Be(NO3)2 is 72.166%.
What is percent composition ?
Percent composition is very straightforward. Percent composition indicates the percentage of each element in a compound by mass. A chemical compound is made up of two or more elements.
Percent composition is important because it allows us to calculate the percentage of each element in a compound. Here, the quantity is measured in terms of grams of the elements present.
For example, if we know the mass and chemical composition of a substance, we can find out the number of moles and calculate the number of atoms or molecules in the sample.
In Be(NO3)2 the percent composition of Beryllium (Be) is 6.775%, Nitrogenium (N) is 21.060% and Oxygenium (O) is72.166%.
Thus, The percent composition of oxygen in beryllium nitrate, Be(NO3)2 is 72.166%.

True or False: Metals usually have stronger electron affinity than non-metals. True or False: Noble gas elements have a very large value for electron affinity. True or False: Negative anions have a larger ionic radius than the atomic radius of their neutral atom.
Explanation:
Metals usually have stronger electron affinity than non-metals:
In the periodic table, the trend of electron affinity is that it increases from left to right across the period and decrease down the group.
False
Noble gas elements have a very large value for electron affinity:
Electron affinity is the change in energy of an atom when an electron is added. Noble gases already have a complete octet configuration hence there is no reason to accept any electrons. This makes their electron affinity value less than or equal to zero.
False
Negative anions have a larger ionic radius than the atomic radius of their neutral atom:
Neutral atoms that gain electron are referred to as anions. The extra electron increases the electron-electron repulsion which pushes the electrons further apart and finally increased radius.
True

The moons of Jupiter
orbit Jupiter because
they are pulled toward
Jupiter. The moons of
Jupiter are too far to
be pulled into Earth's
orbit.
Yes or No
Answer:
Yes
Explanation:
Jupiter is a very large planet. Larger planets usually have stronger gravity, which pulls planets toward each other.
The moons of Jupiter are by Jupiter. (I know, that wasn't a smart thing to say because you know that, but, hey, I had to.) With this being the case, Jupiter is also an inside planet.
- Inside Planets
Planets that are closest to the sun and orbits the sun
There are 2 things that are the cause of the moons of Jupiter not being pulled by earth.
1. Jupiter has strong gravity which pulls the moons, and Jupiter is being pulled by the sun's INCREDIBLE gravity.
2. Earth is an outside planet. It is too far away from Jupiter to attract Jupiter's moons.
- Outside Planet
A planet that is away from the sun, but still orbits the sun
Hope this helps! :D
