Habitats ,Niches and Succession Flashcards
Habitat
described as an area with a particular combination of physical and biological environmental factors that affect which organisms can live within it. ecological “address”
Tolerance
the variety of environmental conditions within which it can reproduce
Optimum Range
Is the range where the environmental conditions enable individuals to find enough energy and nutrient to maintain homeostasis
If one or more environmental conditions, such as temperature rise above or fall below that optimum range then?
individuals experience stress and individuals under it must expend more energy to remain in homeostasis and leaves less energy to grow and reproduce the higher the stress fewer they will produce and fewer of those offspring will survive and when it reaches the tolerance limits individual may survive but not reproduce
Niche
where an organism lives and what it does for a living including the way it interacts with biotic and abiotic factors also includes the range of physical and biological conditions in which it can survive reproduce and the way it obtain resources it needs
Ecological Succession
a series of somewhat predictable events occur in a community over time
Primary succession
Succession that begins on newly formed rock or other areas that have no remnants of an older community
Pioneer species
first species to colonize barren areas ( broad range of tolerance and they break down rock, synthesize organic material, and begin to form new soil)
Secondary Succesion
when a disturbance affects an existing community but doesn’t completely destroy it proceeds faster than primary succession HAS SOIL
Climax communities
area which has reached a stable ecological succession doesn’t always be uniform and stable
