what is meant by extreme habitats?
Organisms, most of them microbes, managing to colonise extreme environments that are unsuitable for more complex life forms.

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.

Habitat [SEP] Extreme habitats
Although the vast majority of life on Earth lives in mesophyllic (moderate) environments, a few organisms, most of them microbes, have managed to colonise extreme environments that are unsuitable for more complex life forms. There are bacteria, for example, living in Lake Whillans, half a mile below the ice of Antarctica; in the absence of sunlight, they must rely on organic material from elsewhere, perhaps decaying matter from glacier melt water or minerals from the underlying rock. Other bacteria can be found in abundance in the Mariana Trench, the deepest place in the ocean and on Earth; marine snow drifts down from the surface layers of the sea and accumulates in this undersea valley, providing nourishment for an extensive community of bacteria.
