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

Organisms belonging to benthos of a lake are

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

  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

  1. Quantity of biomass in a trophic level at a particular period is called as standing crop.

  2. The energy content in a trophic level is determined is determined by considering a few individuals of a species in that trophic level.

  3. The succession that occurs in newly cooled lava is called primary succession.

  4. Rate of succession is faster in secondary succession.

Show answer
Correct Option: B

The adaptation mechanism of chameleon is

adaptations - european woodland and african grassland adapting to a habit plant adaptations adaptations to different ecosystems biology

  1. To hibernate in the winter

  2. Changing colours to suit with its surroundings

  3. To develop scaly skin on its body to maintain moisture

  4. To migrate to long distances in the winter

Show answer
Correct Option: B
Explanation:

Chameleon can change its colour which helps the animal to camouflage itself in the presence of potential predators. Their slow movement and blending into the surrounding environment make it hard for predators to spot them. Their colour changes also help them in mating as they shift colours while communicating with other chameleons. Their colour change also depicts their reactions such as they display darker colours when empty or when under stressed environmental conditions.  Thus, the correct answer is option B.

Tigers and leopards have stripes on their bodies. This adaptation helps them 

adaptations - european woodland and african grassland adapting to a habit plant adaptations adaptations to different ecosystems biology

  1. To keep their bodies cool

  2. To keep their bodies hot

  3. To mix with the surroundings

  4. To look beautiful

Show answer
Correct Option: C
Explanation:

The different types of stripes in tigers and leopards are ideal in proving camouflage to these animals according to their need. The black stripes help the animal to be hidden in the shades of the tree. The stripes on their body look like shadows as they stalk through long grasses in the moonlight. Besides being an adaptation to mix with their surroundings these stripes also act as finger prints for them as no two tigers have same type of stripes.

Thus, the correct answer is option C.
