A man - made ecosystem is
-
Less in diversity
-
More in diversity
-
Man does not make ecosystem
-
More stable then natural ecosystem
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
-
Uniform vegetation
-
Biome
-
Ecosystem
-
Niche
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.
The living organisms of all ecosystems collectively consitute
-
Producers
-
Decomposers
-
Consumers
-
Biosphere
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 word 'ecosystem' was first coined by

All of the above
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
-
Ecotype
-
Blame
-
Ecosystem
-
Population
-
Ephemerals
The highest level of ecological hierarchy is
-
Ecosystem
-
Biosphere
-
Biome
-
Landscape
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.
Major ecological community of plants and animals extending over large natural area is known as
-
Bioregion
-
Biosphere
-
Biota
-
Biome
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
-
Biome
-
Landscape
-
Ecosystem
-
Biotic community
MAB Programme means
-
Man and biosphere programme
-
Man and biodiversity conservation programme
-
Manually aided biosphere conservation programme
-
None of these.
-
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
-
a component in the ecosystem
-
composed of the plants present in the sil
-
life in the outer space
-
composed of all living organisms present on earth which interact with the physical environment.
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:
