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

  1. Pelagic zone

  2. Benthic zone

  3. Lentic zone

  4. Littoral zone
Reveal answer Fill a bubble to check yourself
D Correct answer
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

B Correct answer
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.

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

Benthic organisms are affected most by

  1. Surface turbulance of water

  2. Sediment characteristics of aquatic ecosystems

  3. Water holding capacity of soil

  4. Light reaching the forest floor
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Benthic organisms live on the bottom of aquatic ecosystems, so their distribution and survival are primarily influenced by the physical and chemical characteristics of the sediment.

Which of the following is false?

  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.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Energy content in a trophic level is determined by the total energy flow through that level, not just by considering a few individuals, which would be statistically insignificant.

The adaptation mechanism of chameleon is

  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
Reveal answer Fill a bubble to check yourself
B Correct answer
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 

  1. To keep their bodies cool

  2. To keep their bodies hot

  3. To mix with the surroundings

  4. To look beautiful
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
