List the communities in a successional sequence of secondary succession?

The given communities can be ordered in the secondary succession as grass, shrubs, small trees and large tress.

The life cycle of a plant is characterized by secondary ecological succession. Secondary succession, in contrast to primary succession, is a process initiated by an occurrence such as a forest fire, harvesting, hurricane, etc. that reduces an already established ecosystem (such as a forest or a wheat field to a smaller population of species.

As a result, secondary succession occurs on preexisting soil, whereas primary succession typically takes place in a location lacking soil. Many elements, including trophic interaction, starting composition, and competition, might influence secondary succession. Trade-off with colonization

Therefore, the given communities can be ordered from the small level to higher level as grass, shrubs, small trees and large tress.

Sheila and Jerome are lab partners. They have the following materials at their table:

1 square of aluminum foil, 1 stirring rod, 1 beaker of water, 1 scoop of copper II chloride salt (blue color)


Step 1:Jerome adds all the salt to the water and stirs. The salt crystals disappears and the liquid solution turns a clear blue.

Step 2: Sheila tears up the aluminum foil into small pieces.

Step 3: Jerome dares her to put the foil in his beaker. They see the edges of the foil turn a rusty orange. As they stir, the beaker becomes warm to the touch and a vapor begins to rise from the surface of the beaker. Within a few minutes, the foil has disappeared and the liquid is now clear. There are orange-rust colored flakes floating in the liquid.


Q: Jerome claims that when the salt was added to the water it turned blue and the foil disappeared, these were chemical changes. He went on to explain that the chemical change was due to the fact that the atoms were speeding up. Sheila disagrees claiming that 1 is a physical change and 1 is a chemical change and Jerome’s evidence is incorrect. Who is correct, Jerome or Sheila? Write a scientific explanation (CER) to support your argument.

Helena uses the same force to move an object that has a mass of 12 kg and an object that has a mass of 5 kg. She predicts the 12 kg object will have a greater change in motion. Is she correct?

No, the object with the smaller mass will have a greater change in motion.
No, both of the objects will have an equal change in motion.
Yes, the object with the larger mass will have a greater change in motion.
No, neither object will have a change in motion.

What do fireworks, a fried egg, and a rusting vehicle have in common? They all involve chemical reactions. If two or more elements or chemical compounds come into contact with one another and there is enough energy present, a chemical change may take place.

When a substance undergoes a chemical change, the chemical structure of that substance is altered. A chemical change can also be called a chemical reaction. During a chemical reaction a new substance is formed.

Observe the chemical reaction between bromine and aluminum. Pieces of aluminum are cut from a strip of foil and added to liquid bromine. At first there is no reaction because of the protective oxide coating on the aluminum. But soon an exothermic reaction between bromine and aluminum causes brown fumes of bromine to be given off. But as a new substance, aluminum bromide is produced. White smoke is produced.

The resulting residue is also aluminum bromide. When two compounds or molecules react together to form new substances, they are called reactants. They new substances created plus any resulting ash, water vapor, or carbon dioxide are called products, because they are produced by the reaction.

Some chemical reactions, such as the explosion of fireworks, can happen very fast—in less than a second.

Others, like the rusting of a car, might take years. It is important to carefully examine chemical reactions because there are many ways substances can be changed without a chemical reaction taking place.

Changes of state, for example, from a solid to a liquid or from a liquid to a gas, always involve a physical change rather than a chemical one. Melting sulfur is a good example. When solid sulfur is heated to 120 degrees Celsius it melts and first forms a pale yellow liquid.

In this form the atoms are covalently bonded and the liquid can flow easily. However, heated up beyond 150 degrees Celsius, the result is a dark red liquid that is over 2,000 times stickier. The sulfur may have changed physically but it's still sulfur.

No chemical reaction has taken place. Most of the time changes of state can be reversed by either adding or taking away heat. When water is boiled, for example, water vapor molecules are released in the process.

If you captured all the vapor molecules in a container they would reform again as water droplets once the vapor cooled. When a chemical change occurs it is more difficult to revert the substance back to its original state.
