4.1 Species, communities and ecosystems
ecology-✔✔ the study of the relationship between living organisms, or
between living organisms and their environment
biotic factor-✔✔ living factors in an ecosystem, such as the plants and
animals
abiotic factor-✔✔ non-living factors such as pH, water, wind, soil, etc.
ecosystem-✔✔ the interaction between biotic components (e.g.
communities) and its abiotic environment (e.g. habitat)
habitat-✔✔ the abiotic environment, a location where a species/organism
lives
community-✔✔ a group of populations living and interacting in a particular
area
population-✔✔ a group of organisms of the same species that live in a
particular area at the same time
species-✔✔ a group of organisms that can potentially interbreed and
produce fertile offspring
examples of interbreeding-✔✔ liger (lion + tiger), mule (donkey + horse),
zorse (zebra + horse)
mode of nutrition-✔✔ how an organism obtains organic molecules and
energy
autotroph-✔✔ Producers in the food chain, "Auto" means self, "trophic"
means nutrition Organisms which synthesize its own organic molecules
from simple inorganic substances, derived from the abiotic environment
