PH is a measure of how acidic<span>/basic water is. The range goes from 0 - 14, with 7 being </span>neutral<span>. pHs of less than 7 indicate </span>acidity<span>, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl </span>ions<span> in the water.</span>
Answer:
A. accumulation
Explanation:
Precipitation is where water falls back to the surface of the earth through rain, snow, hail, etc.
Evaporation is where water heats up and turns into a gas.
Condensation is when the water cools down and turns to liquid.
The energy of the ecosystem can be best described as option C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.
Answer:
Hey there.
<em><u>There are three types of scientific investigations: descriptive, comparative, and experimental scenitific investigations.
</u></em>
<em><u></u></em>
fist we have <em><u>Descriptive</u></em> scientific investigations.
Descriptive investigations use careful observations and measurements to develop findings.
Then we have <em><u>
comparative </u></em>Investigation.
comparative investigations Involve collecting data on different populations/organisms, under different conditions (Times of year, locations), to make a comparison. for Example, Using a hand lens to examine the color and texture of four different rocks.
Lastly we have <em><u>experimental</u></em> scientific investigations.
Experimental investigations involve a process in which a "fair test" is designed and variables are actively manipulated, controlled,

Answer:
All organisms that have life, both plants and animals.
Explanation:
You didn't provide an illustration, but I guess I can still help. Biotic factor means that it has life, abiotic means it's not alive (hence the a- at the beginning.) Some biotic factors of a pond ecosystem include: earthworms, fishes, frogs, plants and insects.
