Diversity in Living Organisms

3,829 Questions

The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

Multiple choice zoology adaptations to different ecosystems adaptations to aquatic habitat different ecosystem ecosystem

Organisms belonging to benthos of a lake are

  1. Germs and beetles

  2. Chronomid larvae and red annelids

  3. Daphnia and notonecta

  4. Ranatra and copepods
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Benthos is the community of organisms that live in or near the seabed. This zone is called as the benthic zone. Chronomid larvae, phantom larva, clams, red annelids are some organisms that belongs to benthose of a lake.

Echolocation is a characteristic of

  1. Insects

  2. Birds

  3. Bats

  4. Monkeys

  5. Rats
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The sound travels through the air as a wave and the energy of this wave bounces off any object it comes across. A bat emits a sound wave and listens carefully to the echoes that return to it. The bat's brain processes the returning information. By determining how long it takes a noise to return, the bat's brain figures out how far away an object is. The bat can also determine where the object is, how big it is and in what direction it is moving.

  1. 360 degrees

  2. 270 degrees

  3. 180 degrees

  4. 160 degrees
Reveal answer Fill a bubble to check yourself
B Correct answer

Multiple choice

Why are polar bears almost undetectable to infrared cameras?

  1. nobody looks for them

  2. their fur is almost transparent

  3. they give off no heat

  4. they are very detectable
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
