Question

Write the basis on which an organism occupies a space in its community/ natural surroundings.

Answer 1

Hint: An organism occupies an individual or species level in its community. This level is occupied on the basis of its ecological level of organization or ecological hierarchy.

Complete answer: It is also based on the feeding relationships of that specific organism with the other organisms and the source of their nutrition/ food.
The following are some examples of organisms in its habitat:
1. Camels in the desert.
2. Polar bears in the arctic tundra.
3. Howler monkeys in the canopy of Indonesian evergreen rainforests.
4. Prairie dogs in the grasslands of America, etc.

The following are some factors affecting the presence of an organism or a group of organisms in a place:
1. Abundance of food.
2. Less interspecific competition.
3. Fewer predators that target it.
4. Suitable environmental conditions (abiotic factors like sunlight, water, wind, etc.).

Additional information: Freshwater habitats include rivers, streams, backwaters, lakes, ponds, estuaries, marshes, and bogs. Even though some organisms in these habitats have no specific requirements, the majority have more specific requirements.
These include water velocity, temperature, and dissolved oxygen saturation.
Marine habitats include brackish water, estuaries, bays, seas, intertidal zones, sea bed, coral reefs, and oceans. Other variations of the marine habitat include rock pools, sandbanks, mudflats, brackish lagoons, beaches, and seagrass beds.
The benthic zone or the seabed provides shelter for static organisms that are anchored to the substrate and for a large range of organisms that crawling and burrow into the surface.

Note: Terrestrial habitat types include forests, grasslands, wetlands, and deserts. There are more specific habitats within these broad biomes that have varying climate types, temperature, soils, altitudes, and vegetation types.
