All of us have seen movies and read stories already about animals. We have our own favorite pets; like cats, dogs, birds and the like. Animals can be found in almost any places on earth. They are numerous. Animals have unique characteristics which make Earth beautiful.
Animals have big role in the maintenance of the balance of nature. Although animals look different, they share several common characteristics.
CHARACTERISTICS OF ANIMALS
Animals range in size from the tiny insects to the gigantic whales of the sea. Some have legs to walk on land and fins for swimming in water. Others have wings for flight in the air.
Animals are able to survive in their habitats because of ADOPTATION, animals have body parts that have enabled them to get their own food, find their mates, fend off competition, move from place to place, maintain a constant body temperature, and perform other day- to-day activities.
THE DIFFERENT WAYS OF GETTING AND EATING FOOD OF THE ANIMALS
- Feed on plants – HERBIVORES
- Eat other animals or even members of their own kind – CARNIVORES
- Eat both plants and animals – OMNIVORES
HERBIVORES – this includes cows, carabaos, goats, and horses. They have powerful teeth for crushing and grinding food.
CARNIVORES – they use their sharp fangs to kill their prey. E.g are: lions, tigers, talons and eagles.
OMNIVORES – e.g dogs, cats, and pigs.
ANIMALS’ INSTINCT OF SURVIVAL
1. Live in forests, mountains, deserts, and grasslands.
2. Live in water like ponds, rivers, seas, and oceans
3. Live under the ground
4. Live in cold places
HABITAT is where animals lived. It can be Terrestrial or Aquatic.
2 KINDS OF HABITATS
1. Terrestrial Habitats
2. Aquatic Habitats
Are habitats found on land. Animals that live in terretrial habitats have structures that enable them to move on land. Mammals have legs that allow them to move from one plave to thhe next. Birds use their wings to fly. Snakes use undulatory motion to move on land even though they don’t have legs.
Are habitats that have different characteristics such as temperature, amount of water present, and elevation.
E.g A desert – is a terrestrial habitat that is characterized by having very low rainfall. Thus, animals living in deserts should have the capability to store water in their bodies or perform body processes that require little water. Camels, mammals that thrive in deserts, can store water in their bodies.
In the polar regions, where the climate is cold, animals should have body parts that will allow them to maintain a constant body temperature. Bears have thick coat of fur to keep them warm. Penguins have special feathers that keep them warm too.
Can be marine or freshwater habitats (water-based).
E.g; Fishes have fins that allow them to swim efficiently in the water. Their bodies are also covered with scales. Aside from covering and protecting their bodies, scales also lessen the drag when fishes swim in the water. Fishes also have a swim bladder that allow them to control their buoyancy in the water.
