Animal Worksheet for Class 3: Behavioral & Structural Adaptations

EVS Worksheet : Animals Adaptation For Class 3


The natural world is a tough place to survive . Faced with competition for resources and sometimes hostile climates, life can be even more difficult for animals.

But, in order to beat the odds and survive, some animals adapted to some pretty interesting and unusual ways.


Adaptations are any behavioural or physical characteristics of an animal that help it to survive in its natural environment. An adaptation is a special skill that helps organisms to survive in their harsh and odd environments. Adaptations could be PHYSICAL, PHYSIOLOGICAL, or BEHAVIOURAL.

Adaptations are influenced by environmental and physical factors, including climate, predators and food availability. Animals have needs like food, water, shelter, and breeding. To meet those needs, animals adapt to their environment.

Animal adaptations are behavioural or physical traits that improve an animal’s chance of survival in their environment. Adaptations are influenced by many environmental factors including terrain, climate, and food availability. Animals have needs such as food, water, shelter, and reproduction. To meet those needs, animals have to adapt to their external environment.

Examples of physical adaptations include beak sharpness, fur colour, fish gills, reptile scales, and bird feathers. Animal mimicry and camouflage are other examples of physical adaptations. These are all things that animals have that help them survive in their environment. Animal mimicry is an Interesting adaptation.

These characteristics fall into three main categories: body parts, body coverings, and behavioural.
Any or all of these types of adaptations play a crucial role in the survival of an animal

Some animals have scales, some have nails, and some animals have spots. Some animals migrate, while some animals hibernate.

Behavioural Adaptation:

Actions animals take to survive in their environments. Examples are hibernation, migration, and instincts. Example: Birds fly south in the winter because they can find more food. Structural Adaptation: A characteristic in a plant or in an animal’s body that helps it to survive in its environment.

Social behaviour – some animals live by themselves, while others live in groups.

Behaviour for protection - An animal’s behaviour sometimes helps to protect the animal. For instance the opossum plays dead. A rabbit freezes when it thinks it has been seen.

  • Migration is main example of behavioural adaptations
  • Sharp Claws.
  • Large beaks.
  • Wings/Flying.
  • Feathers.
  • Fur.
  • Scales.

Structural Adaptation

Structural adaptations of animals are the physical features which allow them to compete. Animals have a wide range of structural adaptations including sharp claws to catch prey , dig burrows or scratch trees to signal territories. The scratching of trees is a behavioural adaptation

Examples of Structural Adaptations

  • Giraffe’s long neck.
  • Giraffe’s long necks help them reach food high up in trees that other animals cannot reach Fish’s gills.
  • Beaver’s large pointed teeth.
  • Duck’s webbed feet.
  • Whale’s blubber.
  • Snake’s flexible jaw.
  • Bird’s sharp eyesight and sharp claws (some species)

In general, adaptation is a process that can take hundreds And thousands of years. Favourable traits and behaviours increase an animal’s chance of surviving in his or her environment. This enables that animal to pass those traits and behaviours to their babies through the process of inheritance.

Instructions to solve the worksheet

Given below are some behavioural and structural traits of animals, study them and put a X in the chart to show whether each organism's adaptation is structural or behavioural.

Importance of Environmental Education for kids

  • EVS helps children to develop their own insights into the functioning of several things or understand human processes in their environment. Such interactions with their surrounding environment are immensely important for the healthy development of children.
  • Not only does environmental education offers opportunities for experiential learning outside of the classroom, but it also enables students to make connections and apply their learning in the real world.
  • EVS helps learners see the interconnectedness of social, ecological, economic, cultural, and political issues.
  • By providing environmental education to students they will engage problem-solving techniques of the outer world to their subjects to understand a particular problem by implying outdoor environmental solutions.
  • Environmental Education gives students a new meaning of exploring mother nature to see and resolve the issues which are harmful to the environment and this will also help them in maintaining their own health by doing physical work so that their bodies will be immune from some serious health issues such as short-sightedness, obesity and in some cases even lack concentrations
  • The one major issues which we need to deal with is pollution and if we don’t educate our kids about the hazardous effects of environmental damage there will be no future of the world.
