Introduction About Animal Around Us :
There are many different organisms that live in our world both on land and sea. A habitat is where an animal lives. Animals need food, water, and shelter to live. They find these things in their habitat. Animals are living organisms that grow, reproduce, respire, and give off wastes.
Group of Animal:
Unlike plants, animals cannot make their own food from simple molecules, they can move on their own from place to place, and they show quicker responses to environmental change. There is a great diversity of living organisms on this Earth. There are natural groupings of organisms as they live together. Humans however have developed ways to connect similar organisms that do not live near each other.
Type of Animals:
Animals could be mainly divided into two parts as wild and domestic. However, the domestic animals that live under wild conditions are called Feral Animals. Animals live in habitats on land and in water. Land habitats include forests, grasslands, and deserts. Deserts get very little rain. They can be cold or hot. Oceans are salty water habitats. Most lakes are fresh water habitats. Wild animals have their own preferences to survive in the environment that they live. However, they face an array of problems caused by humans or anthropogenic activities. Hence, the free roaming environment has been reduced to small areas compared to the earlier situations. As a result, the human-wildlife conflict has been resulted.
Wild animals live without direct influence from the human whereas domestic animals live under the care of humans. Domestic animals are trained to obey the human commands but not the wild animals. Some animals live in natural habitats for their homes. Other animals build their own homes. Some animals even live in other animal’s homes. A natural shelter is a home that the animal has made for itself. Animals live in different kinds of homes like:
- holes in the ground
Animals are divided into groups, depending upon how they are alike and different.
Six common groups of animals are: Birds, Fish ,Reptiles, Amphibians, Mammals and Insects.
Classifying Animals According to the Food They Eat:
Animals that only eat plant.A herbivore is an animal that gets its energy from eating plants, and only plants. Many herbivores have special digestive systems that let them digest all kinds of plants, including grasses.
Animals eat only other animals.A carnivore meaning ‘meat eater’ is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue, whether through predation orscavenging. Animals that depend solely on animal flesh for their nutrient requirements are considered obligate carnivores while those that also consume non-animal food are considered facultative carnivores.
Animals that eat both plants and animals.An Omnivore, meaning ‘all-eater’ is a polyphage (“many foods“) species that is a consumer of a variety of material as significant food sources in their natural diet. These foods may include plants, animals, algae and fungi.Omnivores often are opportunistic, general feeders with neither carnivore nor herbivore specializations for acquiring or processing food, and are capable of consuming and do consume both animal protein and vegetation. Many omnivores depend on a suitable mix of animal and plant food for long-term good health and reproduction.
Animals that eat the remains of died animal.Detritivores, also known as detritophages, detritus feeders, detritus eaters, or saprophages, are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces).There are many kinds of invertebrates, vertebrates and plants that carry out coprophagy. By doing so all these detritivores, contribute to decomposition and the nutrient cycles.
Example: Bacteria, Fungi and Protists
Scavengers are typically not thought to be detritivores, as they generally eat large quantities of organic matter, but both detritivores and scavengers are specific cases of consumer-resource systems. The eating of wood, whether live or dead, is known as xylophagy
