Basic needs required for a plant to grow are air, water and sunlight. It prepares its food in the presence of sunlight. Its shoot system or stem respond to light and bends towards the direction of sunlight.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 5

Which is the major component of the living environment?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 5

3. All of these

Explanation: The living environment is made up of various essential components such as water, trees, and the sun, all of which are crucial for life. Water is vital for hydration and biological processes, trees provide oxygen and habitats, and the sun is the primary source of energy for all living organisms through processes like photosynthesis. Therefore, all of these components play a major role in the living environment.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 6

The following is a list of some plants and the habitat in which they live. Which option is mismatched?

Thin skin and scales are the features not suited for tropical regions.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 9

Which of these 4 help polar bears adapt to live in extreme cold climate?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 9

The white fur helps the polar bear to conserve heat and white surfaces are poor radiators of heat. Fat stored under its skin provides insulation against heat loss thus helping the animal to survive in the extreme cold conditions in the arctic region.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 10

Which characteristics protect an animal against cold weather?
(i) Thin skin.
(ii) Thick skin or fur

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 10

They have thick skin or fur to protect them from cold. For example, yaks have long hair to keep them warm

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 11

Which adaptation helps the camel to survive in hot and dry desert?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 11

Camel is called the' ship of the desert'. It is used for transportation. It stores reserve food in the form of fat in its hump for future use. A camel's hump does not hold water at all – it actually stores fat.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 16

Which pair has not been correctly paired?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 16
  1. Camel - Desert: Camels are well adapted to live in desert environments. They can survive with little water and have thick fur that helps insulate them from the heat.

  2. Germs - Air: Germs, or microorganisms, can be found in the air, especially in dust and aerosols. They can spread diseases through the air, making this pairing correct.

  3. Polar bear - Snow: Polar bears are native to Arctic regions, where there is a lot of snow and ice. They are excellent swimmers and primarily hunt seals on the sea ice, making this pairing accurate.

  4. Whale - River: This pairing is incorrect because whales are marine animals that live in oceans. While some smaller species, like dolphins, can enter rivers, true whales do not typically inhabit freshwater rivers.

In summary, the pair "Whale - River" does not represent a correct association since whales are found in saltwater environments, not in rivers.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 17

Which of the following is an abiotic component of habitat?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 17

All non-living things such as soil, water, sunlight, temperature etc. are abiotic component of an habitat. Tulsi, snail and bacteria are living components of an habitat.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 18

Mountains usually have trees that cools the environment. Hence, the animals with thick fur are most likely to be found in mountains, fur insulate the body and keeps the body warm.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 19

Which organism depends on abiotic components for food?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 19

Plants depend on abiotic components for food. They use carbon dioxide, water and sunlight for preparing food by photo-synthesis.

Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 20

Which part of a camel will shrink in size when there is no food for a long time and retain its size when food is available?

Detailed Solution for Olympiad Test: The Living Organisms - Characteristics & Habitats - Question 20
