  2. Decomposers

  3. Water

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

Environment is defined as a natural ecosystem that includes everything around the biotic factors. These are nonbiotic factors. These includes air, water, sunlight. Decomposers are the biotic factors of an ecosystem.

Thus, the correct answer is 'Decomposers.'

Two species in the same habitat can coexist when they

  1. differ in their use of resources

  2. share the same resource in different ways

  3. use the same resource at different times

  4. all of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

2 species that are coexisting in a particular area have few characteristic features to avoid intraspecific competition.

These differ in the use of resources
These share the same resource in different ways
These use the same resource at different times
So, the correct option is 'all of these'

An example of biotic components in nature is

  1. Cells

  2. Organic molecules

  3. Plants

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Biotic components are the living things that shape an ecosystem. Examples of biotic components include animals, plants, fungi, and bacteria. Abiotic components are non-living components that influence an ecosystem. Examples of abiotic factors are temperature, air currents, and minerals.

So, the correct answer is 'D'.

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

  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
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

  1. True

  2. False

  3. Either

  4. Neither
Reveal answer Fill a bubble to check yourself
B Correct answer
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?

  1. pH

  2. Minerals

  3. Organic matter in soil

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