Any change in the lifestyle, the food habits and the body form of an organism in order to make it comfortable in the environment / habitat, is called adaptation. Identify the suitable adaptation given below against each mammal. i) conservation of body heat in large marine mammals like whale (Jaws are modified into baleen plates / Forelimbs are modified into flippers / Fat is deposited in subcutaneous tissue.) ii) Locating food source by bats-( Forelimbs are modified into wings / Hanging upside down using legs / Production of sounds and detection of the echo
Answers
i. Fat is deposited in subcutaneous tissue.
There are many layers of skin or tissue are present in an animal.
The subcutaneous tissues are innermost tissues.
The mammals are ""well-known"" for their warm blood.
The whales which are living in the deep oceans need warm blood.
The whales need to conserve their body heat, which can be done by adding more amount of fat into the innermost layer of their skin.
Thus, their body heat will not escape their body.
ii. Production of sounds and detection of the echo.
The bats use echoes to detect the position of the objects.
The method of finding prey from the surrounding using echo is used Bio-Sonar.
The bats are unable to see its prey during night time.
So, they used this echo-location technique to find it prey.
