Multiple choice commercial applications issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

When we destroy a forest we destroy

  1. An ecosystem

  2. The environment

  3. Population of wild life

  4. Food and shelter of wild animals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When we destroy a forest, we destroy an ecosystem. It is because ecosystem constitutes of both abiotic and biotic components. The biotic components constitute all the living organisms present in the ecosystem, i.e. plants and animals. Whereas, abiotic components constitute the environmental factors like air, soil, water etc. When a forest is destroyed, it results in the loss of food and habitat of wild animals, due to which the population of wildlife is threatened. The loss of forest also results in deforestation, which affects the environment by raising the temperature and causing a flood. So, the correct option is A.

Which one of the following is the definition of ecosystem?

  1. A localised association of seven plants and animals.

  2. Different communities of plants, animals and microbes, together with their physicochemical environments.

  3. Different communities of plants and microbes, plus their physicochemical environments.

  4. A community of organisms interacting with one another.

B Correct answer
Explanation

An ecosystem consists of the biological community of living organisms that occurs in some particular area and the physical and chemical factors that make up its nonliving or abiotic environment. There are many examples of ecosystems - a pond, a forest, an estuary, a grassland. 

 Therefore, the correct answer is option B.

Two components of ecosystem are

  1. Plants and animals

  2. Trees and fungi

  3. Living and non living

  4. Frogs and man
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The ecosystem is comprised of various food chains in which the organisms interact with each other. There is also the involvement of the non-living forms. The living form is the biotic component and the non-living forms are the abiotic components. The producers, consumers and decomposers are the biotic components. Sunlight, air and water are the abiotic components. 

Thus, the correct answer is option C.

An ecosystem is a complex interacting system of

  1. Individuals

  2. Population

  3. Communities and their physical environment

  4. Communities and their soil condition
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An ecosystem includes living things in a given environment, their interaction with each other, and also with their non-living environment i.e., weather, earth, sun, soil, climate, and atmosphere. Thus the correct answer is option C.

Which of the following is true in an ecosystem ?

  1. Animals can live without plants

  2. Plants can live without animals

  3. Animals can survive for long without plants

  4. Plants can survive for long without animals
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The ecosystem is a community like a system of checks and balances between physical elements and living beings. Removal of any one component, living or non-living will eventually lead to the destruction of the ecosystem. So, plants and animals cannot live without each other. However, if animals are removed plant would still survive longer as they can perform photosynthesis.
The correct answer is 'plants can survive for long without animals'

An ecosystem may be a small or a large sized based on kind of 

  1. Habit

  2. Habitat

  3. Components

  4. Molecules
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Habitat is the environmental area where particular organisms live. Hence the size of the habitat determines the size of an ecosystem. More the number of the organism more the area will be covered and thus the size of the particular ecosystem increases.

Interaction between biotic and abiotic factors is called as _________. 

  1. Ecology

  2. Ecosystem

  3. Niche

  4. Biomes

B Correct answer
Explanation

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.

The least inclusive level of ecological organization that includes interactions among living and non-living factors is 

  1. A community

  2. A population

  3. A species

  4. A biosphere

  5. An ecosystem
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation
A. A community is a group of populations of different species in a given area.
B. Population is a group of individual organisms of the same species in a given area.
C. Species is a group of individuals which resemble each other in morphological, physiological, biochemical and behavioral characters.
D. The planet Earth along with its atmosphere (air, land, and water) that sustain life is called biosphere.
E. An ecosystem is stable, a settled unit of nature consisting of a community of organisms interacting with each other and with their surrounding physical and chemical environment.
Hence the ecological organization that includes interactions among living and non-living factors is an ecosystem.
So, the correct answer is 'An ecosystem'.

An ecosystem contains

  1. Producers

  2. Decomposers

  3. Lentic

  4. Xeric
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

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. 

Thus, the correct answer is 'Both A and B.'

Well known ecosystem ecologist is

  1. P. Maheshwaii

  2. E.P. Odum

  3. M.S. Swaminathan

  4. W. Sutherland
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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.'

Thus, the correct answer is 'E.P. Odum.'
