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

Littoral zone is found along

  1. High mountain

  2. Sea

  3. River

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

1) The zone at the edge of a lake or sea or in an aquatic habitat which is alternatively exposed to air is called 'Littoral zone'.

2) Therefore, sunlight is also available here which penetrates to the sediment level and immersed in water, which helps and allow to grow aquatic plants.
3) This coastal zone is rich producers from the surface to bottom, with a large number green alga
4) Organisms which are mobile such as crabs, snails, limpets are usually found in these areas.
So, the correct answer is 'Sea'

Aquatic photodiffraction produces zones

  1. Euphotic, disphotic and aphotic

  2. Aphotic, euphotic and disphotic

  3. Euphotic, aphotic and disphotic

  4. Disphotic, aphotic and euphotic
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Aquatic light penetration creates three distinct zones. The euphotic zone receives sufficient light for photosynthesis. The disphotic zone receives some light but insufficient for photosynthesis. The aphotic zone receives no sunlight at all. This order from surface to depth is fundamental to aquatic ecosystem structure.

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
Reveal answer Fill a bubble to check yourself
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
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.

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

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.

Multiple choice zoology option a: neurobiology and behaviour structure and function of ear perception of stimuli neural control and coordination

The human ear is equipped to register sounds of frequencies between

  1. 20 to 20,000 cycles per second

  2. 1000 to 2000 cycles per second

  3. 5000 to 7000 cycles per second

  4. 5000 to 10,000 cycles per second

  5. 10,000 to 20,000 cycles per second
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The middle ear is mainly known as a sound amplifier of the ear. It has ear ossicles to amplify the sound. The human ear can respond to minute pressure vibrations in the air if they are in the audible frequency range of 20 Hz - 20,000 Hz or cycles per second.

So, the correct answer is option A.
