(i) Timing their foraging. (ii) Migratory activities. (iii) Reproduction.
Flowering in plants. Timing of foraging or migration in plants.
The herbs and shrubs growing in the forests are adapted to photosynthesis optimally under very low light conditions.
Birds will be able to cope with global warming; they are eurythermal and can tolerate a wide range of temperatures.
Stenothermal animals have tolerance to a narrow range of temperatures and hence their geographical distribution would be much affected.
The levels of thermal tolerance of species determine their geographical distribution, because temperature affects the physiological functions by affec...
Ecological niche of an organism represents the range of conditions it can tolerate, the resources it utilises and its functional role in the ecosystem...
Variation in the intensity and duration of temperature. Variation in precipitation.
Rotation of earth around the Sun. Tilt of the earth on its axis.
Ecology at the organismic level is essentially physiological ecology, which tries to understand how different organisms are adapted to their environme...
False, dS/dt = rN is the equation describing logistic growth.
False, Organisms living in water bodies (lake, sea, river) do not face any water related problems.
True, Small animals like shrews and humming birds are rarely found in polar regions.
True, The success of mammals is due to their ability to change their body temperature according to their surroundings.
True, Zooplanktons enter a state of suspended development, called diapause, under unfavourable conditions.
