Under which environmental condition would primary succession occur ​
astraxan [27]

Explanation:

Primary succession starts off with the modification of a previously unoccupied area along with increasing variation- this occurs in barren areas devoid of life like sand dunes, and lava flows. Communities in a primary succession include:

-barren rock

-bacteria and fungi

-mosses and lichen

Further Explanation:

Succession involves small scale changes within a community that occur repeatedly over the life of that community.

Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:

  • colonizing species exploiting uninhabited areas (Primary succession)
  • becoming a habitable and increasingly complex community
  • there is increased diversity of organisms (Secondary)

The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.

However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

What happens to the concentration of oestrogen at ovulation?
frez [133]

Answer:

When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle). The follicle becomes the corpus luteum and this produces oestrogen and progesterone which inhibit FSH and LH production by the pituitary.
