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

Components of environment are

  1. Biotic

  2. Abiotic

  3. Resources and regulatory factor

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Environment is composed of biotic (living) and abiotic (nonliving) components. All components of environment are closely related and they interact with each other.  Environment is composed of both environmental resources and regulatory factor. 

Biotic components include producers, consumers and decomposers.
Abiotic components include temperature, light intensity, moisture, water levels, air currents, energy radiation, carbon dioxide levels, pH of water, soil etc.
Some component of the environment serves as resources while other serves as regulatory factors. 

Resources include air, water, biota, land and geological and natural resources. Regulatory factors include temperature, light, weather etc.

Thus, the correct answer is option D.

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.

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

Ecosystem contains

  1. Food web

  2. Food chain

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In ecology, a food web describes the feeding connections between organisms in a biotic community. Both energy and nutrients flow through a food web, moving through organisms as they are consumed by an organism above them in the food web. A single path of energy through a food web is called a food chain. A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

Biotic components include

  1. Only producers

  2. Producers, consumers and decomposers

  3. Only consumers

  4. Only producers and consumers
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The biotic components of an ecosystem are the lifeforms that inhabit it. The life forms of an ecosystem aid in the transfer and cycle of energy. Examples of biotic components are producers and consumers. There are three main types of consumers: herbivores, carnivores and omnivores. 

Therefore, the correct answer is option D.

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

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.
Reveal answer Fill a bubble to check yourself
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.

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

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. 

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

What are biotic components?

  1. The living components

  2. The non-living components

  3. Both living and non-living

  4. None of these
Reveal answer Fill a bubble to check yourself
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.

  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.
