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

  1. Limnetic zone

  2. Profundal zone

  3. Littoral zone

  4. Benthic zone

Show answer
Correct Option: A
Explanation:
Phytoplanktons are microscopic floating organisms present in the first exposed layer of water, this zone has abundance of light
So, the correct answer is 'Limnetic zone'

The zone at the edge of a lake or ocean which is alternatively exposed to air and immersed in water is called.

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

  1. Pelagic zone

  2. Benthic zone

  3. Lentic zone

  4. Littoral zone

Show answer
Correct Option: D
Explanation:

Littoral zone is the shallow coastal zone. Light is available upto bottom in this zone. Therefore, producers are found throughout from surface to bottom in this zone. Rooted vegetation occurs along shores. Consumers are also available throughout, i.e., from surface to the bottom in this zone.

Bottom dwellers, where no light occurs is found in

  1. Benthic zone

  2. Abyssal zone

  3. Pelagic zone

  4. Lotic zone

  5. All of the above

Show answer
Correct Option: B
Explanation:

The abyssal zone is the abyssopelagic layer or pelagic zone, that contains the very deep benthic communities near the bottom of oceans. The benthic zone begins from shore to continental shelf. The deep sea floor is called as the abyssal plain.

Increased surface UV leads to increased __________ ozone

  1. Germs and beetles

  2. Chronomid larvae and red annelids

  3. Daphnia and notonecta

  4. Ranatra and copepods

Show answer
Correct Option: B
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.

Thus, the correct answer is option 'Chronomid larvae and red annelids.'

Benthic organisms are affected most by

  2. Sediment characteristics of aquatic ecosystems

  3. Water holding capacity of soil

  4. Light reaching the forest floor

Show answer
Correct Option: B
