A man - made ecosystem is

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Less in diversity

  2. More in diversity

  3. Man does not make ecosystem

  4. More stable then natural ecosystem

Show answer
Correct Option: A
Explanation:

Man made or artificial ecosystems have low stability. Because usually man is interested in only a few economically beneficial species only and only those species will be used by man to create an ecosystem e.g., agriculture field is a man made artificial ecosystem having only those plants which are economically beneficial. Thus, the correct answer is option A.

Large unit of land having different types of plants and animals is known as

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Uniform vegetation

  2. Biome

  3. Ecosystem

  4. Niche

Show answer
Correct Option: B
Explanation:

Biome is a large regional unit delimited by a specific climatic zone, having a particular major vegetation zone and its associated fauna. For example, tundra desert, temperate deciduous forests etc. 

Biome is different from ecosystem. it can be understood as a huge ecosystem or the biggest ecosystem on earth. 
Niche is altogether a different concept. Niche is related to ecological role of a species.

The living organisms of all ecosystems collectively consitute

  1. Producers

  2. Decomposers

  3. Consumers

  4. Biosphere

Show answer
Correct Option: D
Explanation:

Ecosystem is a segment of nature or biosphere consisting of a community of living beings and the abiotic or physical environment both interacting and exchanging materials between them.

The living organisms or biotic components of all the natural ecosystem put together, constitutes the biosphere of Earth.

The word 'ecosystem' was first coined by

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Weaver and Clements

  2. A. G. Tansley

  3. E. P. Odum

  4. All of the above

Show answer
Correct Option: B
Explanation:

The ecosystem is a segment of biosphere consisting of a community of living beings and the abiotic or physical environment, both interacting and exchanging materials between them. The word ecosystem was first coined by Tansley in 1935 and previously the term 'biocoenosis' was used.

Plant species having a wide range of genetical distribution evolve into a local population known as

  1. Ecotype

  2. Blame

  3. Ecosystem

  4. Population

  5. Ephemerals

Correct Option: A

The highest level of ecological hierarchy is

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Ecosystem

  2. Biosphere

  3. Biome

  4. Landscape

Show answer
Correct Option: B
Explanation:

The highest level of ecological hierarchy is biosphere because it consists of the surface and atmosphere of earth or another planet.  It cannot be ecosystem because that consists of only biological communites, similarly, it cannot be biomes because a biome consists of many ecosystems but is a part of the biosphere, it cannot be a landscape because it is a land that does not have a fixed natural boundary. 

So the correct answer is 'Biosphere'. 

Major ecological community of plants and animals extending over large natural area is known as

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Bioregion

  2. Biosphere

  3. Biota

  4. Biome

Show answer
Correct Option: D
Explanation:

A large naturally occurring community of flora and fauna occupying a major habitat is known as biome e.g. forest or tundra

A regional ecological unit having a specific climate is

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Biome

  2. Landscape

  3. Ecosystem

  4. Biotic community

Show answer
Correct Option: A
Explanation:
A biome is a unit that has its own community of plants and animals that thrive in a specific climate.
A landscape is a patch of a land that does not have a fixed natural boundary. An ecosystem is formed when many biological communities interact with each other and their environment.
A biotic community is a group of similar organisms which live together.
So the  correct answer is a 'Biome.'

MAB Programme means

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. Man and biosphere programme

  2. Man and biodiversity conservation programme

  3. Manually aided biosphere conservation programme

  4. None of these.

Show answer
Correct Option: A
Explanation:
  • Man and the Biosphere Programme (MAB) is an intergovernmental scientific programme.
  • It was initiated in 1971 by UNESCO. 
  • It aims at establishing a scientific basis for the improvement of relationships between people and their surrounding environments.
  • So, the correct option is 'Man and Biosphere programme'.

Biosphere is 

zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

  1. a component in the ecosystem

  2. composed of the plants present in the sil

  3. life in the outer space

  4. composed of all living organisms present on earth which interact with the physical environment.

Show answer
Correct Option: D
Explanation:

The living world consists of many ecosystems. There are 2 main factors present in an ecosystem, namely abiotic (nonliving) and biotic (living). All of these factors interact with each other. The living world is divided into a different sphere, namely:

1. Lithosphere
2. Hydrosphere
3. Atmosphere
All these spheres together constitute the biosphere.
So, option D is the correct answer.
