Answer: 2) secondary succession
Explanation:
Ecological succession is the change in the biotic community of the ecosystem due to the changes occurring in the abiotic components such as water, soil, atmosphere and others. These changes occur with respect to time until the ecosystem attains the stability.
A secondary succession can be define as the changes which occur after a catastrophic event or ecological disturbance. Such changes brings stability with the help of precursors of previously existing species at the same place.
According to the given situation, secondary succession could have occurred this is because of the fact that the forests fire can burn the vegetation in an area. The burn sites will regrow into a healthy forests because of some of the precursors of previously existing plant species like seeds, stem, roots and others which will help in regrowth of new plants.
You don’t have enough information listed in your question to give an answer. For example, what does DE and BC represent? What is your parameters?
Answer:
A
Explanation:
Let's say x represents adult tickets, and y represents child tickets.
We know that 2 adult tickets, x, and 2 child tickets, y, added together total $26. This can be written as:
2x+2y=26
We also know that 2 adult tickets, x, and 3 child tickets, y, added together total $31. This can be written as:
2x+3y=31
So, our system is:
2x+2y=26
2x+3y=31
Therefore, choice A is correct.
Answer:
When a warm air mass moves into an area of cooler air, the boundary between the air masses is called a warm front. The warmer, less-dense air slides up over the cooler, denser air in a wide, gentle slope. As the warm air cools, its relative humidity increases, and the water vapor condenses into clouds.
