Frequently Asked Questions:
Q1. Define synecology?
Ans.The study of the organisms living together in an interrelated
fashion in a given environment is termed as synecology or
community ecology.
Q2. Name the intermediate zone of vegetation in between the
two distinct types of communities?
Ans. Ecotone
Q3. Define phenolgy?
Ans. phenology refers to the appearance of the manifestations
at certain seasons of the year.
Q4. Name different qualitative characters of community?
Ans.floistic composition,stratification,periodicity,vitality and
vigour,life forms,dispersion and sociability,association of species.
Q5. What are chamaephytes?
Ans.These are those plants whose buds are close to ground or
maximum up to 25 cm.
Q6. What are hemicryptophytes?
Ans.These are those plants whose buds remain covered under
surface soil,and are protected .These include annual or biennial
herbs.
Q7. What are cryptophytes?
Ans.Those pants whose buds remain buried under soil,such as
bulb and rhizomes.These plants are mostly found in the arid
regions of the world.
Q8. What are therophytes?
Ans.These are the ephemerals or seasonal plants that complete
their life cycle quickly under favourable conditions and during
the rest of unfavourable remain in the form of seeds.
Q9. Define frequency?
Ans.It refers to the degree of dispersion of individual species in

the given area.
Q10. what are the different characteristics of community?
Ans.The characteristics of community are as,species
diversity,growth form and structure,dominance,succession,troph
ic structure.
Q11. What is difference between analytic and synthetic
characters?
Ans. Directly observed or measured characters are in a sample
plot are called the analytical characters, whileas characters
derived from the measurement of analytical characters
are called synthetic characters.These reflect the pattern of
distribution and performance of different species.
Q12. What is biological spectrum? What are the major classes
of life forms?
The ratio of the life forms of different species in terms of
percentage in any floristic community is called the biological
spectrum or phytoclimatic spectrum.
The major classes of life forms are, a).Phanerophytes,
b).Chamaephytes, c).Hemicryptophytes ,d).Cryptophytes,
e).Therophytes.
Q13. Define the following:
(a)Stratification, (b) Life form
Ans.Stratification:It is the way in which plants of different
species are arranged in different vertical layers in order to make
full use of the available physical and physiological requirements.
Life forms:It is the vegetation appearance of plants based on
the size of plants ,shape of leaves,branching of stem, crown
of foliage, longitivity,locaton of overwintering parts or over
summering parts etc.
Q14. what are the different classes of abundance?
Ans. There are five class of abundance which are as, a)Rare, b)
Occasional, c)Frequent, d)Abundant and, e)Very abundant.
Q15. Define physiognomy?
Ans.It is the appearance or “look” of a stand. It is based on a
Consortium for Educational Communication
number of qualitative and quantitive characteristics such as the
kinds and dominance of species, lifeform, population density,
cover, height, sociability, stratification etc.
