Give an example for:
$(a)$ An endothermic animal
$(b)$ An ectothermic animal
$(c)$ An organism of benthic zone
$(a)$ Endothermic animal: Birds such as crows, sparrows, pigeons, cranes, etc. and mammals such as bears, cows, rats, rabbits, etc. are endothermic animals.
$(b)$ Ectothermic animal: Fishes such as sharks, amphibians such as frogs, and reptiles such as tortoise, snakes, and lizards are ectothermic animals.
$(c)$ Organism of benthic zone: Decomposing bacteria is an example of an organism found in the benthic zone of a water body.
Emergent land plants that can tolerate the salinities of the sea are called.
$I.$ Biochemical adaptation are seen in organisms living in great depth of the ocean to face crushing pressure
$II.$ Allen's rule is explain mammals living in colder climates
$III.$ Altitude sickness is caused because of body not getting enough oxygen due to low atmospheric pressure at high altitude
$IV.$ Desert lizards lack behavioural means to manage to their body temperature
Choose the correct option for above adaptations
Altitude sickness which includes nausea, fatigue and heart palpitations occurs due to
Body compensates low oxygen availability at high altitudes by
$I.$ increasing $RBC$
$II.$ decreasing binding affinity of haemoglobin
$III.$ increasing binding affinity of haemoglobin
$IV.$ increasing breathing rate
$V.$ decreasing breathing rate
