You're right! It is the first one, energy and matter within living organisms
Answer:
Small fish, crustaceans, and water-dwelling insects eat algae, so they are going to be affected if an new species is introduced and is water based, also the new species its the algae at a rapid pace, a bunch of organisms will be in danger because some of the organisms eats algae as a primary source of food. If there is something that can make this species go extinct for sometime until it is possible algae can grow as fast as they eat it, then there would be a bunch of sea creatures/organisms affected by this huge change. Not only will the small fish, and other sea creatures/organisms will be affected but it'll also disrupt the ocean food chain, including us human! Because we eat fish, some people depend on algae because if the algae kept getting ate up by this "new" species EVERYTHING else would be also disrupted. Microscopic animals wouldn't have enough food, fish wouldn't have enough oxygen and plants would lose some of the carbon dioxide they need to grow, so these organisms DEPEND on algae for their LIFE!
Explanation:
It is a prehistoric bug that is mostly closely related to the arachnids of today. I lacks a spinneret though. It is one of the first trigonotarbids to ever be described. (It looks like a spiky tick. Seriously)

Answer:
Volume
Explanation:
In chemistry, the CONCENTRATION of a solution is the amount of a substance present within a volume of another substance. In other words, the concentration refers to the amount of a solute dissolved in a particular volume of a solvent to make a solution.
Concentration can be expressed in mass per volume i.e. g/cm³ or mol per volume i.e. mol/L or mol/dm³ etc. The amount of a substance is measured in Mass or mole, while the volume of a substance in Litres (L).
