Orlov [11]1 year ago

"The experimental hypothesis may be that if Asian worms are introduced into a <u>deciduous forest</u>, the soil's nutritional composition will alter. The control group would consist of a region of the forest that has been worm-free in some way. But in order to serve as a control, this forest would experience the same amount of sunshine, heat, and precipitation. In order to determine if Asian worms actually have an impact on the forest ecology, the scientists could then analyze the amounts of nitrogen, phosphorus, and sulfur in the two portions of the forest."

Deciduous forest- A deciduous forest is one that is mostly made up of trees that shed their leaves in the fall.

When plants undergo photosynthesis, they take in water and other nutrients from the soil and carbon dioxide from the air to prod
Vinil7 [7]

Answer:

In an ecosystem photosynthetic plants act as producers wheres other organism act as consumers.

Explanation:

Green plants undergo photosynthesis to produce their own food as a result they are called producers and are placed in the first tropic label of energy pyramid.

          The other organism that intake green plants are called primary consumers for example grasshopper. The primary consumers are placed in the second tropic label of energy pyramid.

           The other consumers are termed as secondary consumers or primary carnivores that feed on primary consumers For example Snake because it eats grasshopper and is placed in the third tropic label.

         Finally the tertiary consumers or secondary carnivores consumes secondary consumers to intake energy from them.For example Hawk eats snake,as a result hawk act as secondary carnivores and are placed in the top of the energy pyramid.

When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity?
KiRa [710]

Answer:

c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules

Explanation:

A solution contains a solvent (water in this case) and a solute (sucrose in this case). A solution can either be saturated or unsaturated depending on whether it can still dissolve a solute or not.

According to this question, the 0.7 M sucrose solution does not dissolve the sucrose (solute) any longer. This implies that the sucrose solution is getting SATURATED. The saturation of the sucrose solution occurs because the amount of solutes is equating the amount of solvent in the solution.

The solubility of a solution depends upon polarity. The solute molecules (sucrose) adhere to the polar regions of the water molecules (solvent). When this occurs to the point where no other sucrose molecule can adhere, the solution becomes SATURATED so there is no room for more sucrose molecules.

Ecotourism is when people are encouraged to tour natural environments, often of endangered species, in order to observe wildlife. You see, when people can see the beautiful places in nature that are at risk, they will work to conserve the environments. Transportation through these places uses the land as a resources without taking anything from it. Non-Extractive Resources are pieces of land and places in nature that benefit the economy without people extracting resources or artificially developing things within the ecosystems.

Metals on the ocean floor aren't renewable. They are formed over long periods of time, and the organisms that feed on them will become extinct without it. For example, iron is one of the most heavily mined metals in the ocean, as well as a primary food source for phytoplankton—who are one of the species at the base of the marine food pyramid, meaning they are essential to the survival of other species.
