Study Notes
Habitat and Niche
- Habitat encompasses biotic (living) and abiotic (non-living) factors that impact an organism's existence.
- Small organisms often inhabit limited areas within broader ecosystems visible to humans.
- Organisms can survive and reproduce in varying conditions, even when those conditions differ from their optimal environment.
- The full range of physical and biological conditions an organism utilizes is termed its ecological niche.
Competition and Symbiosis
- Competitive exclusion principle: No two species can occupy the same niche simultaneously in a shared habitat, leading to resource competition.
- Intraspecific competition occurs among individuals of the same species, while interspecific competition occurs between different species.
- Commensalism is a symbiotic relationship where one organism benefits while the other is not affected.
- Parasitism involves one organism living on or inside another, causing harm to the host.
- Mutualism is a symbiotic relationship from which both species derive benefits.
Ecological Succession
- Ecological succession refers to the gradual changes within a community that follow a disturbance.
- Primary succession occurs in areas devoid of any life or soil remnants from previous communities.
- Pioneer species are the first to colonize an area during the primary succession.
- Secondary succession takes place in areas that have been partially disturbed, allowing life to regenerate quickly.
Biodiversity and Resilience
- Biodiversity refers to the variety of habitats, communities, and ecological processes present in the biosphere.
- Species richness is the measure of different species represented in a given area.
- Genetic diversity is the total of all the varied genetic information of a single species or all species on Earth.
- Ecological resilience is the capacity to recover from disturbances and adapt to changes in the environment.
