G7-8 ECOLOGY

Ecology is the study of organism-environment interaction.

Conservation and biodiversity emphasize the interdependence of endangered species.

Sustainable resource management aims to prevent resource depletion.

Restoration ecology aims to recover biodiversity and ecosystem services.

Natural selection is guided by a breeder and produces order and complex function

Descent modification is the process by which random genetic mutations occur

All life on Earth is related according to the theory of common descent

Charles Darwin and Alfred Russel Wallace worked together in discovering natural selection

High species diversity enhances ecosystem stability and resilience.

Invasive species can cause extinctions of native plants and animals and alter habitats.

Overexploitation means harvesting species from the wild at rates faster than the natural population can recover.

Evolution is the process by which new species arise and existing species adapt to their environment through gradual changes in their genetic makeup.
