Answer:
because it is a sign that there are more producers for the consumers.
Explanation:
An ecosystem consist of the abiotic or inorganic components, the animals[consumers], the plants[producers] and the decomposers. An ecosystem simply means the environment of organisms that are living together and the way these organisms interact with another.
The producers that is the plants are the ones manufacturing food by themselves either by photosynthesis or chemosynthesis and the consumers are the ones relying on the producers for food.
The ecosystem is still healthy even when there's still a lot of consumers in it because it shows that there are come producers that is to say the producers are more also. If this is not the case, then the ecosystem will not be healthy as the consumers will eat the producers until the producers will not be enough.

Jerome had read about plate tectonics and the mid-Atlantic ridge. He investigated by reading further, learning that evidence existed to show volcanic activity was happening along the mid-Atlantic ridge. How do the pillow-shaped rocks found there provide evidence that volcanic activity is taking place? A. They form only when molten material cools slowly in warm water. B. They form only along subduction zones in the trenches of the Atlantic. C. They form only when lava erupts above the water when the air is cool. D. They form only when molten material hardens quickly in cold water.
In chemistry experiment it is determined that 4.2 moles of aluminum oxide are needed to completely react with a sample of sodium. How many molecules of aluminum oxide are there in 4.2 moles? After an experiment, 35.6 g of carbon were recovered. How many moles of carbon is this?
Answer:
Aluminium Oxide = 2.5×10²³ molecules
Carbon = 2.96 moles
Explanation:
1 mole of aluminium oxide contains 6.02× 10²³ molecules, hence 4.2 moles will contain 4.2 ×6.02×10²³ molecules
for carbon, number of moles = Mass/ Molar Mass = 35.6/12.01 = 2.96 mole

explain how a colored light is produced from an atom.
Answer:
When the atoms of a gas or vapor are excited, for instance by heating or by applying an electrical field, their electrons are able to move from their ground state to higher energy levels. This energy corresponds to particular wavelengths of light, and so produces particular colors of light.

What is the result of excess nutrients (nitrates) in North Carolina waters?
A.Algae growth is high
B.Algae growth is low
C.Algae growth is moderate
Answer:
A. Algae growth is high
Explanation:
Substances that contains high concentration of nitrates, phosphates etc add nutrients to the water body. This is because organisms like ALGAE consider these compounds nutrients needed for their growth and development. The process whereby these nutrients becomes excessive in a water body is referred to as EUTROPHICATION.
Eutrophication of a water body i.e excessive nutrients like nitrates in a water body like the North Carolina waters being described in this question will lead to rapid and excessive growth of algal species. This increase in algal growth can cause the water body to be low in oxygen content and ultimately become inhabitable by living organisms.

Mass = 12.75
Thus, 12.75g of Sodium Nitrate can be formed
As per the balanced reaction of lead nitrate and sodium iodide, one mole of lead nitrate requires 2 moles of sodium iodide. The number of moles of sodium iodide is 0.1 moles and that of lead nitrate is 0.075. 0.075 moles requires 0.15 moles of NaI but it is deficient. Thus, NaI is the limiting reactant.
What is limiting reactant?A limiting reactant in a reaction is the one with fewer number of moles or insufficient to completely react with the reagents. Thus it determines the yield of the products.
Here the balanced equation of the reaction is:
[tex]\rm Pb (NO_{3})_{2} + 2NaI \rightarrow 2 NaNO_{3} + PbI_{2}[/tex]
Two moles of sodium iodide is required for one mole of lead nitrate.
The molar mass of NaI = 149.89 g/mol
molar mass of lead nitrate = 333.2 g/mol
Number of moles of 25 g of lead nitrate = 25 /333.2 = 0.075 moles
Number of moles of NaI in 15 g = 15 / 149.89 = 0.10 moles.
The number of moles of NaI required to react with 0.075 moles = 0.075 × 2 = 0.15 (since one mole need 2 moles of NaI)
We have only 0.1 moles of NaI. Hence NaI is the limiting reactant.

How could sinking a ship to create an artificial reef address the problem?
A.
More divers would come to the area to explore both reefs.
B.
Many divers would go to the artificial reef instead of the natural reef.
C.
There would be more places for new species to enter the ecosystem.
D.
There would be fewer places for marine organisms to live.
Answer:
C. There would be more places for new species to enter the ecosystem.
Explanation:
The Shipwrecks established artificial reefs that address the problem of a natural reef.
The artificial reefs provide a stable growing area for corals, and habitat for fishes and new organisms along with food sources that is found in natural reefs. This helps to increase the growth of marine life.
Hence, the correct answer is "C. There would be more places for new species to enter the ecosystem."
