Imagine a picture of Mrs. Foster's "meadow" as she likes to call it. Of the two types of ecological succession, which one is occurring in the meadow? Be sure to include the following in your constructed response:

the term and definition of the type of succession occurring in the meadow a description of what can be expected to grow/live in the meadow over time if it is left alone
how the meadow's type of ecological succession is different from the other form of ecological succession

Secondary succession

Explanation:

Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas.  Some examples of these areas are regions where the soil is not capable of supporting life.  This process is because as lava flows, newly formed dunes or rocks are left from a retreating glacier.   Secondary succession occurs in areas where earlier communities that have existed have now been discharged. It is represented by smaller-scale disturbances that do not eliminate all life and nutrients from the environment.  Mrs. Foster's "meadow," as she likes to call it, there is a specific succession taking place and it is known as secondary.  

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
