The great barrier reed along the cast coast of Australia can be categorized as?

  1. Biome

  2. Ecosystem

  3. Community

  4. Population


Correct Option: A
Explanation:


  • A biome is a community of plants and animals that have common characteristics for the environment they exist in. 
  • They can be found over a range of continents. 
  • Biomes are distinct biological communities that have formed in response to a shared physical climate. 
  • For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests and The great barrier reed along the cast coast of Australia.
  • Hence, The great barrier reed along the cast coast of Australia can be categorized as Biome. 
  • So, the correct answer is 'Biome'.

Last level in ecological hierarchy in which only living factors are being studied:-

  1. Species

  2. Community

  3. Ecosystem

  4. Biome


Correct Option: D
Explanation:

There are 4 levels of hierarchy in an ecosystem, the organism level, population level, community level or ecosystem level and the biosphere level. Among them the biosphere level is the highest level and represents the totality of all things on Earth, including their interactions. The biosphere includes all ecosystems on Earth and how they interact together. So, the correct option is 'biome'.

Ecological niche of an organism represents

  1. The resource it utilizes

  2. Functional role in the ecological system

  3. The range of conditions that it can tolerate

  4. All of these


Correct Option: D

  1. Climax Community

  2. Dis-Climax Community

  4. Ecological Succession


Correct Option: B

What is total mass of atmosphere?

  1. $5.148^{*}10$

  2. $4.148^{*}10^{18}$

  3. $3.148^{*}10^{18}$

  4. $2.148^{*}10^{18}$


Correct Option: A

Which one of the following sequences represents the CORRECT taxonomical hierarchy 

  1. Species, genus, family, order

  2. Order, genus, family, species

The Great Barrier Reef along the east coast of Australia can be categorized as

  1. Population

  2. Community

  3. Ecosystem

  4. Biome


Correct Option: D
Explanation:

'The Great Barrier Reef' is considered as a biome. Since biomes are climatically and geographically defined as contiguous areas with similar climatic conditions on the Earth, such as communities of plants, animals, and soil organisms, and are often referred to as ecosystems. 'The Great Barrier Reef' is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres.

Community is total number of animals and plants

  1. In any area

  2. In any area over a unit of time

  3. In any area over a unit of time per thousand individuals

  4. None of the above


Correct Option: B
Explanation:

In ecology, a community or biocoenosis is an assemblage or associations of populations of two or more different species occupying the same geographical area and in a particular time. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time. 

Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations.

The term, 'ecosystem' was coined by

  1. Odum

  2. Tansley

  3. Richter

  4. Both b and c


Correct Option: B
Explanation:

The term ecosystem was first coined by Roy Clapham in 1930, but it was ecologist Arthur Tansley, who fully defined the ecosystem concept.

Life forms are used in the preparation of

  1. Pod chain

  2. Ecological pyramids

  3. Biological spectrum

  4. Quardats and transects


Correct Option: C
Explanation:

The biological spectrum is made up of all living organisms divided into three domains, coexisting across various levels of biological organization.
