Interaction between biotic and abiotic factors is called as _________.
-
Ecology
-
Ecosystem
-
Niche
-
Biomes
Interaction between biotic and abiotic factors is called ecosystem. Study of ecosystem is called ecology. The study of interaction and habitat or organisms in certain area is called niche and major ecosystems is called bio-mes.
Which of the following explains stable ecosystem?
-
Requires a constant energy source
-
Requires a living system
-
Is self-sustaining
-
Requires cycling of materials between the living system and the environment
-
All of the above
The least inclusive level of ecological organization that includes interactions among living and non-living factors is
-
A community
-
A population
-
A species
-
A biosphere
-
An ecosystem
Biotic factors are
-
Chemical factors of soil which affect life
-
Physical factors of soil which affect life
-
All living organisms which influence other organisms
-
Factors of atmosphere which affect life
(c) Living organisms have effect on other living organisms and these constitute biotic factors or living factors.
An ecosystem contains
-
Producers
-
Decomposers
-
Lentic
-
Xeric
An ecosystem consists of biotic and abiotic omponents. Biotic or living things involve producer, consumers and decomposers. Abiotic or nonliving things involve air, water, soil. An area with very little water is called as xeric or desert ecosystem. A lentic ecosystem is an ecosystem which consists of still water.
Biotic community along with its interacting physical environment comprises
-
Phytosociology
-
Phytogeography
-
Ecosystem
-
Ecology
Biotic community along with its interacting physical environment comprises ecosystem. The biotic community involves living things like plants, animals, microorganisms. The physical environment is called as abiotic community or nonliving things. It includes air, water, land, etc. Ecology is the study of interactions of organisms with one another and with environment.
Well known ecosystem ecologist is

E.P. Odum

Ecosystem ecology is the study of living (biotic) and nonliving (abiotic) components of an ecosystem and their interactions within an ecosystem. Well known ecosystem ecologist is E. P. Odum. Eugene Pleasants Odum is well known for his pioneering work on ecosystem ecology. He wrote a book on 'Fundamentals of Ecology.'
Stability of ecosystem depends, upon
-
Primary productivity
-
Number of producers
-
Number of consumers
-
Interchange between producers and consumers
Stability of ecosystem depends upon interchange between producers and consumers. Producers and consumers occupy different trophic levels of a food chain. High interactivity between producers and consumers makes the ecosystem to be independent of outside factors for its stability.
Given below are the characteristic features of an ecosystem
(a) Little diversity
(b) Little cycling of nutrients
(c) High productivity
These features are correct for
-
Forest ecosystem
-
Cropfield ecosystem
-
Grassland ecosystem
-
More than one option is correct
Why are crop fields known as artificial ecosystems?
-
Crop fields are man made.
-
Some biotic and abiotic components are manipulated by humans for the production of crop.
-
Both A and B.
-
None of the above.
