Which of the following is an example of primary succession?
kiruha [24]

Answer:

B. the appearance of lichens and mosses in an area where a glacier has recently melted away

Explanation:

Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.

Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.

According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

Elephants are considered K-strategists because they give birth to only one calf at a time and most have five years in between ha
kicyunya [14]

Answer:

Type I curve

Explanation:

The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).
