Animals 
Based on Class
Fish
Fish are aquatic animals that have
scales, fins and gills, and are the
largest class of animals that inhabit
seas, oceans, lakes and rivers.
Birds have a characteristic body
covered with feathers and start
life from eggs.
Mammals are animals that suckle
and are animals with the most diverse
species on earth. Mammals come in all
shapes and sizes.
Reptiles are vertebrate animals
that are cold-blooded and have
scales all over their bodies.
Amphibians are a group of animals
that can live in two places, namely in
water and also on land.
Invertebrates are animals that
do not have vertebrae. The skeleton
of invertebrate animals is generally
found outside the body (exoskeleton).

FAQs on Poster: Animal Life - Science Class 5

1. What are the main characteristics that define animal life?
Ans.Animal life is primarily characterized by multicellularity, the ability to move at some stage in their life cycle, heterotrophic nutrition (obtaining food by consuming other organisms), and complex organ systems. Animals also have specialized cells that perform specific functions and reproduce sexually or asexually.
2. How do animals adapt to their environments?
Ans.Animals adapt to their environments through various means such as physical adaptations (like camouflage or body structure), behavioral adaptations (like migration or hibernation), and physiological adaptations (like changes in metabolism). These adaptations enhance their survival and reproductive success in their specific habitats.
3. What are the different classifications of animals?
Ans.Animals are classified into several groups, primarily based on similarities in their physical and genetic characteristics. The main classifications include vertebrates (animals with a backbone, such as mammals, birds, reptiles, amphibians, and fish) and invertebrates (animals without a backbone, such as insects, arachnids, mollusks, and crustaceans).
4. Why is biodiversity important in animal life?
Ans.Biodiversity is crucial in animal life as it contributes to ecosystem stability, resilience, and productivity. A diverse range of species ensures that ecosystems can function effectively and adapt to changes, providing essential services like pollination, nutrient cycling, and habitat provision, which are vital for the survival of all living organisms.
5. How do animals communicate with each other?
Ans.Animals communicate with each other using various methods, including vocalizations (like bird songs or wolf howls), body language (like postures or facial expressions), chemical signals (like pheromones), and visual signals (like color changes). Effective communication is essential for social interaction, mating, and establishing territory among animals.
