Question

Community dynamics are related to
(A)Population growth in an ecosystem
(B)Recycling of nutrients in an ecosystem
(C)Flow of energy in an ecosystem
(D)Ecological succession

Answer 1

Hint: As time changes, change in structure and component of the community is also seen. This is what exactly means by community dynamics. In general conditions, the community is in equilibrium. Community refers to interacting groups of various species in its habitat.

Complete answer:
Ecological succession is the process that describes how the structure of a biological community is changing over time.

Additional Information: The ecological condition is mainly of two types i.e primary succession and secondary succession.
Primary succession is the steps of community changes that occur in a completely new habitat that has never been settled before. For instance, a newly quarried rock face or sand dunes.
Secondary succession is the series of community changes that occur on a previously colonized, but disturbed or damaged habitat. For example, after trees falling during a woodland, land clearance, or burning in that land is commonly seen.
Secondary succession is far more commonly observed and studied than primary succession. The most common type of secondary succession includes responses to natural disasters or causes like fire, flood, and severe winds, and to human-created or man-made disturbances like logging and agriculture. In secondary succession, the soils and organisms got to be left unharmed so there's how for the new material to rebuild
So, the correct answer is ‘Ecological succession’

Note: Succession occurs on many various timescales, starting from a couple of days to many years.It can take many years for a climax woodland to develop, while the succession of invertebrates and fungi within one cowpat (cow dung), could also be over within as quickly as in 3 months.
