why would an animal need an habitat?
To find food, shelter, protection and mates for reproduction.

name two small animals that have their homes in the soil Earthworms and Snails what is a habitat? It is the type of natural environment in which a particular species of organism lives. how are environmental factors related to it? Animal communities are reliant on specific types of plant communities. how many different types are there? Terrestrial habitat, Freshwater habitats, Marine habitats, deserts which favours the presence of amphibians etc can you please give an example of the environmental factors that you mentioned Terrestrial habitat types include forests, grasslands, wetlands and deserts, Freshwater include rivers, streams, lakes, ponds, marshes etc, Marine include brackish water, estuaries, bays, the open sea, the intertidal zone and further variations include rock pools, sand banks, mudflats etc. and what about the second type? They  include rivers, streams, lakes, ponds, marshes and bogs. are there microhabitats? Yes, every habitat includes large numbers of microhabitats. how does the first animal that lives in the soil move? They crawl faster primarily by taking longer "strides" and a greater frequency of strides. what kind of regeneration abilities does it have? They have the ability to regenerate lost segments, but this ability varies between species and depends on the extent of the damage. what economic impact does it have? They are used in vermiculture, the practice of feeding organic waste to earthworms to decompose food waste. has it ever been considered as an invasive species? From a total of around 7,000 species, only about 150 species are widely distributed around the world. what kind of nervous system does it have? Central nervous system do they have sense organs? Yes, Epidermal receptors what are these? They are sense organs distributed all over the epidermis of an Earthworm which contains columnar receptor cells. what is meant by extreme habitats? Organisms, most of them microbes, managing to colonise extreme environments that are unsuitable for more complex life forms.

Habitat [SEP] Introduction
In ecology, a habitat is the type of natural environment in which a particular species of organism lives. A species's habitat is those places where the species can find food, shelter, protection and mates for reproduction. It is characterized by both physical and biological features. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every organism has certain habitat needs for the conditions in which it will thrive, but some are tolerant of wide variations while others are very specific in their requirements.
