Questions Related to habitat and adaptation

Which of the following examples show the interdependency of biotic and abiotic factors?

evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Frigid climates do not support lizards and other cold-blooded animals

  2. Relation between water and life

  3. The need of sunlight for the process of photosynthesis

  4. All of the above

Show answer
Correct Option: D
Explanation:
  • The biotic components of the ecosystem are the producers and consumers. The abiotic or the non-living components include soil, water, light, inorganic substances.
  • Both biotic and abiotic factors are interdependent in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.
  • Examples showing the interdependency of biotic and abiotic factors include Frigid climates do not support lizards and other cold-blooded animals, Relation between water and life and the need for sunlight for the process of photosynthesis.
  • So, the correct answer is 'All the above'.

An ecosystem is made up of one type of community.

evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. True

  2. False

  3. Either

  4. Neither

Show answer
Correct Option: B
Explanation:
Ecosystem is a community of different organisms that interact with each other and with their surroundings or environment. A community is a group of populations of different species present in a given area. An ecosystem is made up of different communities. It includes different populations which interact with the biotic components and abiotic components of environment.
Hence, the statement given in the question is not correct.
So, the correct answer is 'False'.

Which of the following are Edaphic factors?

evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. pH

  2. Minerals

  3. Organic matter in soil

  4. All of the above

Show answer
Correct Option: D
Explanation:
  • Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. For example, rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight.
  • The edaphic factor is an abiotic factor relating to the physical or chemical composition of the soil found in a particular area. For example, the pH of the soil, Minerals present in the soil and organic matter in the soil.
  • Hence pH, Minerals and organic matter in soil are examples for Edaphic factors because these are physical or chemical composition of the soil found in a particular area. 
  • So, the correct answer is 'All the above'.

Only living things form a part of our habitat.

evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Our habitat includes both biotic components like micro-organisms, plants, animal etc and also abiotic components like soil, water, atmosphere etc

So, the correct answer is 'False'

Show answer
Correct Option: C

A $400$km thick, bright layer around the sun is known as _______.

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Photosphere

  2. Chromosphere

  3. Terrestrial

  4. None o fthese

Show answer
Correct Option: A
Explanation:

Photosphere is the lowest layer around the sun in which the energy of the sun is emitted as light. Due to this the layer appears bright. It is approximately 400 km in thickness. So, the correct option is 'Photosphere'.
