Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Which of the following is a climatic factor?

  1. Oxygen

  2. Temperature

  3. Soil structure

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

The constituents of the environment, which directly or indirectly influence the form and functioning of organisms in any specific way are known as environmental factors. They are of two types: abiotic and biotic. 

The abiotic factors are of four types-
  1. Climatic (light, air, temperature, humidity, precipitation)
  2. Edaphic (soil)
  3. Topographic (surface behaviour of earth)
  4. Fire 
Therefore, the correct answer is option B.

If all the plants of the world die, all the animals will also die due to shortage of

  1. Cold air

  2. Oxygen

  3. Timber

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Plants maintains the balance of oxygen and carbon dioxide in the atmosphere. The plants perform photosynthesis and releases oxygen. The oxygen released by the plants is taken by the animals which is used for breakdown of food and release energy. If all the plants will die the animals will also die due to shortage of oxygen.
So, the correct answer is option B.

Source of energy in ecosystem is

  1. Sun

  2. ATP

  3. Sugar made by plants

  4. Green plant
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The source of energy in an ecosystem is the sun. The solar energy is trapped by green plants and converted into biologically useful form i.e., carbohydrates. All the consumers depend either directly or indirectly on green plants for nutrition. The energy flow in an ecosystem is always unidirectional i.e., solar radiation to producers to herbivores to carnivores.

Which of the following is a source of energy to an ecosystem?

  1. Solar energy

  2. Sugar stored

  3. Heat liberated during respiration

  4. ATP
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In an ecosystem, green plants trap solar energy and convert it into sugars which are utilised by all the living organisms and also passed on to successive trophic levels. Thus, the correct answer is option A.

In an ecosystem of abiotic components which of the following occur?

  1. Flow of energy

  2. Cycling of materials

  3. Consumers

  4. Flow of energy and cycling of materials
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In an ecosystem plants produces their own food by utilising solar energy, water and carbon dioxide, which is then transfer to the successive trophic levels. Some of the minerals are locked in living systems as constituents of protoplasm. These minerals are returned to environment through the decomposition of death and decay of organisms.Thus, the correct answer is option B.

Which one of the following components of ecosystem comes from outside?

  1. Oxygen

  2. Temperature

  3. Insects

  4. Energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In an ecosystem, the ultimate source of energy is the sun. The solar energy is trapped by producers and converted to usable biochemical compounds like carbohydrates. These carbohydrates are passed on successively to higher trophic levels. Thus, the correct answer is option D.

Source of energy in ecosystem is

  1. Sun

  2. Sugar produced in photosynthesis

  3. Green plants

  4. ATP
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An ecosystem consists of living things like producers, consumers and decomposers and nonliving things like air, water, land. The ultimate source of energy in an ecosystem is sun. The plants in presence of sunlight synthesize its food. From plants, the energy is transferred to primary consumers and secondary consumers and decomposers. 

The correct answer is 'Sun.'

Pick the odd one out
Natural gas, Sun, Bio-mass, Wind.

  1. Natural gas

  2. Sun

  3. Bio mass

  4. Wind
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Natural gas is a non-renewable source of energy that is made of hydrocarbons, primarily methane. Its usage is subjected to the exhaustion because its formation takes time. Sun, biomass wind are the renewable sources of the energy. Their usage does not result in their exhaustion.

Hence, the correct answer is 'Natural gas'

Which of the following is most ecologically relevant factor ?

  1. Precipitation

  2. Temperature

  3. Soil

  4. Wind
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Precipitation is any form of a liquid or solid water particles that falls from the atmosphere and reach the surface of the earth. Its effect deflect the temperature, wind and humidity. 
So the correct answer is 'Precipitation'.
