Match the following:

Camels can survive a week or more without water.

When an animal or plant copies a characteristic of some other organism in order to better its chances of survival and reproduction is called:

If the temperature of the Earth increases gradually and the surroundings become drier, which of the following plant would more likely survive?

Succulents grow in which region?

The arctic environment has lower temperatures ranging between −22°C and 6°C, with snow covering the majority of the area. Which adaptation would be favourable for the survival of a population of organisms in this environment:

What is INCORRECT about hibernation.

An adaptation where animals move to a different habitat in search of food, water and shelter is known as:

The flexible jaw of a snake is a: 

During hibernation, animals show which of the following changes?

______________ allows an organism to survive better in its environment

• Such changes occur in the organisms that helps them to survive better in the environment. This is called adaptation.
• These changes occur at genetic level and pass on to the next generation.
• These adaptations can be structural, behavioral or physiological. 
• For example, most of the animals found in desert have a thick dermis layer on their body that assure minimum water loss. 

Animals migrate because of:

• Animals migrate according to the season.
• The conditions of the place in a season becomes unfavorable.
• The animals can't survive or breed in such conditions, so they move to the other place. The distance of the travel can be around 25 miles.
• They migrate because of high or very low temperature conditions or unavailability of food. 
• Bar headed geese migrate from Himalaya to south Asia in winter season.
• They travel 1000 miles. 
• The condition of this place when becomes unfavorable they again move to the Himalayas.

The phenomenon in which animals go into a deep sleep is known as

• Hibernation and aestivation are also types of behavioural adaptation.
• During winters animals show hibernation.
• They avoid normal activities like hunting or roaming.
• Also they slower their metabolic rate, heart rate and breathing rate.
• So that they can save their energy.
• Most of the bears and snakes go into a deep sleep. 

Camels can drink up to how many liters of water in one go?

• Camel is found in the desert.
• The temperature is around 50 C during summer.
• There is a lesser availability of food and water. The environment is also dry.
• So the camel has to survive in such conditions and it shows many adaptations like it can live without drinking water for 7 days.
• It can live for a maximum of 15 days without drinking water.
• It can drink around 100 to 200 water once. 
• The water is stored in its blood.
• Also in the hot temperature, it is required to resist water loss.
• So, they do not sweat much and due to low metabolism, their body temperature is lesser.

Arctic foxes living in polar regions show which adaptation?

• The Arctic fox is found on ice packs
• They show many adaptations to survive in the cold environment.
• They have grey or brown fur.
• They can change the colour of fur according to the season.
• During winter their coat colour is white.
• When summer starts the white fur sheds and a thin grey coat covers its body.
• Later the grey fur becomes brown.
• So, this is how the arctic fox show camouflage.
• This helps in blending with the colour of the environment so that it can hide from the prey and can easily hunt. 

Populations do not change if their environment changes.
