Photosynthesis happens when plants use the energy of the sun and other reactants to produce sugar and water that they need to survive. The reactants of photosynthesis are energy, carbon dioxide, and water. The products are glucose and oxygen.
<span>Energy (Sun) + CO2 (Carbon dioxide) + H2O (Water) -> C6H12O6 (Glucose) + O<span>2 (Oxygen).

Photosynthesis is generally performed by various plants and bacteria.
Explanation:
Mealworms probably originated in the Mediterranean region, but are now present in many areas of the world as a result of human trade and colonization. The oldest archaeological records of mealworms can be traced to Bronze Age Turkey.
Answer:
or 0.0079.
Explanation:
Joyce is planting tulips in her garden.
Number of red (R) bulbs = 5
Number of white (W) bulbs = 5
Total number of ways to plant 10 bulbs in one row is
![\text{Total ways}=\frac{10!}{5!5!}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20ways%7D%3D%5Cfrac%7B10%21%7D%7B5%215%21%7D)
![\text{Total ways}=\frac{10\times 9\times 8\times 7\times 6\times 5!}{5\times 4\times 3\times 2\times 1\times 5!}](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20ways%7D%3D%5Cfrac%7B10%5Ctimes%209%5Ctimes%208%5Ctimes%207%5Ctimes%206%5Ctimes%205%21%7D%7B5%5Ctimes%204%5Ctimes%203%5Ctimes%202%5Ctimes%201%5Ctimes%205%21%7D)
Cancel out common factors.
![\text{Total ways}=252](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20ways%7D%3D252)
It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.
Required outcomes are
RRRRRWWWWW and WWWWWRRRRR
![\text{Required outcomes}=2](https://tex.z-dn.net/?f=%5Ctext%7BRequired%20outcomes%7D%3D2)
Formula for probability:
![Probability=\frac{\text{Required outcomes}}{\text{Total ways}}](https://tex.z-dn.net/?f=Probability%3D%5Cfrac%7B%5Ctext%7BRequired%20outcomes%7D%7D%7B%5Ctext%7BTotal%20ways%7D%7D)
![Probability=\frac{2}{252}](https://tex.z-dn.net/?f=Probability%3D%5Cfrac%7B2%7D%7B252%7D)
![Probability=\frac{1}{126}](https://tex.z-dn.net/?f=Probability%3D%5Cfrac%7B1%7D%7B126%7D)
![Probability\approx 0.0079](https://tex.z-dn.net/?f=Probability%5Capprox%200.0079)
Therefore the required probability is
or 0.0079.
Answer:
The answer is D
Explanation:
Because as the energy travels from one animal to the other the energy decreases. For example a gazelle eats the grass right? And then a lion eats the eats the gazelle. The gazelle got energy from the grass it's body already used some so when it's eaten the lion only gets what energy the gazelle has leftover
