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.

A Correct answer
Explanation

  • The ecosystem is comprised of various food chains in which the organisms interact with each other.
  • There is also involvement of the non-living forms. The living form is the biotic components and the non-living forms are the abiotic components. The producers, consumers, and decomposers are the biotic components. 
Thus, the correct answer is option A.

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.

Multiple choice evs - i issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

Ecosystem has two components

  1. Plants and animals

  2. Weeds and trees

  3. Biotic and abiotic

  4. Frogs and man
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
An ecosystem includes the interaction of the living things i.e biotic factors in a given area with the non-living environment i.e abiotic factors such as weather, earth, sun, soil, climate and atmosphere
So, the correct answer is 'Biotic and abiotic'

A Correct answer
Explanation

An ecosystem includes the interaction of the living things i.e biotic factors in a given area with the non-living environment i.e abiotic factors such as water, weather, earth, sun, soil, climate and atmosphere. Bacteria, Daphnia and Chlorella form the biotic component of the ecosystem. Thus the correct answer is option A.

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.

Which of the following is an abiotic component?

  1. Plants

  2. Animals

  3. Soil

  4. Microorganisms
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The correct answer is 'soil'

The biosphere consists of two components-biotic and abiotic component. Biotic components are the living things while non-living things make up the abiotic component. Plants, animals and microbes being living make up the abiotic component whereas soil being non-living is a part of an abiotic sphere.
