BIOXII14: ECOSYSTEM

344538 Choose the incorrect statement

1 Phytoplanktons are the pioneers in the aquatic ecosystem
2 Rate of succession is faster in secondary succession
3 The energy content in a trophic level is determined by considering a few individuals of a species in that trophic level
4 The succession that occurs in newly cooled lava is called primary succession
BIOXII14: ECOSYSTEM

344539 In secondary succession the species that invade depend on the

1 Condition of the soil
2 Availability of water
3 The environment and seeds or other propagules
4 All of them
BIOXII14: ECOSYSTEM

344540 Assertion :
Succession and evolution would have been parallel processes.
Reason :
The present day communities in the world have come to be because of succession that has occurred over millions of years since life started on earth.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
BIOXII14: ECOSYSTEM

344545 Statement A :
In the successive seral stages there is a change in the diversity of species of organisms, increase in the number of species and organisms as well as an increase in the total biomass.
Statement B :
Succession is a process that starts in an area where living organisms are there - these could be areas where organisms always existed.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
BIOXII14: ECOSYSTEM

344546 During ecological succession

1 The numbers and types of animals remain constant
2 The changes lead to a community that is in near equilibrium with the environment and is called pioneer community
3 The gradual and predictable change in species composition occurs in a given area
4 The establishment of a new biotic community is very fast in its primary phase.
