Ecology is
Ecology is a branch of biology that studies the interactions among animals and their affecting environment, which includes both biotic and abiotic components
Ecology is a branch of biology that studies the interactions among organisms and their affecting environment, which includes both biotic and abiotic components
Commensalism is
when one species benefits from the interaction and the other is neither harmed nor benefits
when one species benefits from the interaction and another is harmed
when two different species both gain benefits from the interaction
when one species is the predator and the other the prey
Species diversity
The number of plants in a habitat
The number of humans in an area
The number of different species in a habitat
The number of animals in a habitat
A symbiotic relationship is
Different species living together for an extended time

when one species is the predator and the other the prey
Evenness is
How evenly the individuals in a community are distributed among the different species
A measure for the total number of the species in a community
How much space a species takes up based on how many there are of that species
