community ecology
beneficial interactions
If two organisms interact such that both benefits, that is mutualism or a mutualistic relationship.
if one organism helps another without receiving any benefit, that is a facilitation, the first organism facilitates the presence of other.
Nurse plants are an example; these are plants that alter small area of habitat immediately below themselves such that it is more favorable to the survival of seedlings of other plants.

A community is a group of species that occur together at the same time and place.
population biology focuses on the member of a single species, their growth, interbreeding, survival, and so on.
The more or less predictable sequence of changes is called Succession.
The disturbed patch undergoes succession until it becomes spruce fir forest again which is the climax community.
Interconnectedness of species: food chains and food webs
The simplest is to choose one predator, then identify its main prey and the plant species that supports them. this direct line of consumption would be a food chain.
If we trace all the prey of the top carnivores, and then trace the food sources of each of the those prey species and so on we obtain a network of numerous interrelationship called a food web.
energy flow web is the trace of how energy flow between organism.
The presence or absence of certain species called keystone species.
