This would be primary succession. Primary succession is succession starting from bare rock. Succession may start with weathering of the rock to create small pockets of lose soil. Seeds of pioneer plants may be carried by the wind to fall into pockets of soil with sufficient moisture to allow germination. The growth of pioneer plants will further break up the bare rock, creating a deeper layer of soil. As the plants grow, dead leaves and roots enrich the soil with organic content. Small animals start to colonise the area, such as gophers, who further break up and enrich the soil. The plants change from pioneer plants to plants of a specific biome. Succession will continue in this fashion until until an equilibrium is achieved.
Red pandas are going extinct because of habitat destruction. They also reproduce slowly, that's why they're one of the most endangered animals.. :(
Most likely A or E.. not completely sure but A and E<span />
Hello. This question is incomplete. The full question is:
"Scientists are testing the effect of different scrubber technologies on the removal of pollutants from coal power plants. The scrubbers use a slurry of limestone and water. Which of the following best describes the impact of modifying the slurry by increasing the amount of limestone? The amount of sulfur dioxide released will decrease. A The amount of ground-level ozone released will decrease. B The amount of water released will increase. C The amount of carbon monoxide released will increase.
"
Answer:
The amount of sulfur dioxide released will decrease.
Explanation:
As you may already know, coal is a fossil fuel and burning it releases many toxic gases into the atmosphere, including sulfur dioxide.
A suspension of water and limestone, allows the calcium present in limestone to enter into reaction with sulfur dioxide, forming calcium sulfide and decreasing the emission of sulfur in the atmosphere.
The greater the amount of limestone in this suspension, the less sulfur dioxide will be released into the environment.
