ANSWER FOR QUESTION`2
Ecological interactions
The ecological interactions that take place within a specific area are generally classified into four levels: populations, communities, ecosystems and the biosphere.
Look at the following illustration which shows the levels of organisation.
(JUST SEE THE SECOND DOCUMENT !! )
Individuals live together in populations. Different populations together make up a community. Communities together with the non-living things in their surroundings make up an ecosystem. All the ecosystems on Earth make up the biosphere.
Interdependence
All organisms in an ecosystem depend upon each other. If the population of one organism rises or falls, then this can affect the rest of the ecosystem.
A simple food chain is:
grass → rabbit → fox
If the foxes in the food chain above were killed, the population of rabbits would increase because they are no longer prey to the foxes. As a result the amount of grass would decrease because the increased population of rabbits would be eating it.
Often very small changes to ecosystems have large consequences, which can be difficult to predict. This means that all the organisms in an ecosystem are dependent upon each other. We call this interdependence.
