Give one example for each of the followi | Class 12 Biology Chapter Organisms and Population, Organisms and Population NCERT Solutions

i. Mango etc.

Shelford’s law of tolerance defines that there are upper and lower limit of tolerance threshold values on the environment gradient beyond the species cannot survive. As the upper limit of tolerance of temperature factor is known is eurythermal organisms.

ii. Thermus aquaticus, bacteria etc.

Hot springs are also known as thermal spring which contains water with the higher temperature.

iii. Xenophyophores, amphipods etc.

Trench is an excavation which is very deeper and narrow when compared along with its length.

iv. Mites, snails, bugs, beetles etc.

Compost pit is defined as the degrading the biodegradable substances in a dig or a pit for the decay so that manure and fertile substances are produced for the soil.

v. Some Cuscuta species.

Parasitic plants are those which gets nutrition from the other plants. Those plants which gets nutrition are parasites and other by which plant they are getting nutrition are known as hosts.

vi. Eucalyptus etc.

Shelford’s law of tolerance defines that there are upper and lower limit of tolerance threshold values on the environment gradient beyond the species cannot survive. As the lower limit of tolerance of temperature factor is known as stenothermal organisms or species.

vii. Mites, worms, beetles, bugs etc.

Soil organisms are those which are found in soil.

viii. Bacteria, fungi, crustaceans etc.

Benthic organisms are those which are found in this benthic zone or bottom zone.

ix. There are some proteins that acts as antifreeze compounds like Antarctic Notothenioids.

Antifreeze compounds are those substances that lowers the freezing point which protects from getting ill from the effects of ice such as ethylene glycol etc.

x. Amphibians, reptiles etc.

Those organisms whose homeostasis is highly influenced by external environment factors like temperature, nutrients etc.
