Ecology (Ernst Haeckel)An organism’s relationship to its biotic and abiotic environment. Ecologists study factors that affect spatial distribution and abundance of organisms.

Community ecology Species interactions Species diversity CompetitionNiche, tolerance ranges, habitat Predation & parasitism Models & mimics Keystone species—starfish & mussels Species diversity
Ecosystem ecology Gross and net productivityTrophic levels and food webs Producers, consumers, decomposers
ORGANIZATION IN THE BIOSPHERE. WHAT DOES BIOLOGY MEAN? THE STUDY OF LIVING THINGS WE’VE LOOKED AT THE BUILDING BLOCKS OF LIVING THINGS… BUT WHERE DO.
ORGANIZATION IN THE BIOSPHERE. LIVING THINGS, AS WE KNOW THEM, ARE CONFINED TO A SPECIFIC AREA OF EARTH THAT WE CALL… THE BIOSPHERE !!
What is Ecology?.
