Which of the following is NOT a primary producer in marine ecosystems?

  1. Phytoplankton

  2. Seaweed

  3. Coral

  4. Zooplankton


Correct Option: C
Explanation:

Coral, while an important component of marine ecosystems, is not a primary producer as it relies on symbiotic relationships with photosynthetic organisms for sustenance.

The process by which coral reefs form is known as:

  1. Calcification

  2. Photosynthesis

  3. Biomineralization

  4. Nitrogen Fixation


Correct Option: A
Explanation:

Calcification is the process by which coral polyps secrete calcium carbonate, forming the hard skeletons that build coral reefs.

Which of the following is NOT a type of coral reef structure?

  1. Fringing Reef

  2. Barrier Reef

  3. Atoll

  4. Seagrass Bed


Correct Option: D
Explanation:

Seagrass beds, while important marine ecosystems, are not a type of coral reef structure.

The mutualistic relationship between clownfish and sea anemones is an example of:

  1. Commensalism

  2. Parasitism

  3. Mutualism

  4. Predation


Correct Option: C
Explanation:

In this relationship, the clownfish gains protection from predators by living among the stinging tentacles of the sea anemone, while the anemone benefits from the clownfish's ability to attract prey.

Which marine organism is known for its ability to filter large volumes of water, removing plankton and other particles?

  1. Whale Shark

  2. Manta Ray

  3. Blue Whale

  4. Great White Shark


Correct Option: A
Explanation:

Whale sharks, the largest fish species, are filter feeders that swim with their mouths open, filtering plankton and other small organisms from the water.

The process by which nutrients are recycled from dead organic matter back into the marine ecosystem is known as:

  1. Decomposition

  2. Photosynthesis

  3. Respiration

  4. Transpiration


Correct Option: A
Explanation:

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing nutrients back into the ecosystem.

Which marine organism is known for its ability to change color and texture to camouflage itself with its surroundings?

  1. Octopus

  2. Sea Turtle

  3. Dolphin

  4. Jellyfish


Correct Option: A
Explanation:

Octopuses have specialized cells that allow them to change their color and texture, enabling them to blend in with their surroundings and evade predators.

The process by which marine organisms produce offspring that are genetically identical to themselves is known as:

  1. Sexual Reproduction

  2. Asexual Reproduction

  3. Budding

  4. Fragmentation


Correct Option: B
Explanation:

Asexual reproduction is the process by which an organism produces offspring without the involvement of gametes (sex cells).

Which marine organism is known for its ability to produce light through a process called bioluminescence?

  1. Firefly Squid

  2. Sea Cucumber

  3. Starfish

  4. Lobster


Correct Option: A
Explanation:

Firefly squids are known for their bioluminescent displays, which they use to communicate and attract prey.

The process by which marine organisms move from one location to another in search of food, mates, or favorable environmental conditions is known as:

  1. Migration

  2. Dispersal

  3. Aggregation

  4. Recruitment


Correct Option: A
Explanation:

Migration is the long-distance movement of marine organisms, often undertaken seasonally or in response to environmental cues.

Which marine organism is known for its ability to filter large volumes of water, removing plankton and other particles?

  1. Whale Shark

  2. Manta Ray

  3. Blue Whale

  4. Great White Shark


Correct Option: A
