Environmental Biology Exam Questions and
Answers with Verified Solutions | Latest
Updated 2026
Environmental literacy demonstrate knowledge and
understanding of the
affect the environment has on humans and
the
effects that humans have on the
environment
Ecosystem services - human dependence on ecosystems
- examples: water purification,
biogeochemical
cycling, natural resources such as
firewood, and
food
Ecological footprint - human domination of ecosystems
- examples: deforestation, freshwater
salinization
syndrome, climate change/global warming,
agricultural nutrient runoff
Sustainability - human stewardship of ecosystems
- sustainable societies must live within
regenerative
capacity of Earth; meet present needs
without
compromising future generations
, Sustainable development development meets present and future
human
needs without damaging environment and
biodiversity
Habitat destruction the single greatest cause of modern
extinction
Habitat fragmentation habitats are broken up into fragments
mostly too
small to support populations
Wildlife corridors connect habitat fragments
Invasive species - introduced species are accidentally or
intentionally moved from native locations
to new
geographic regions
- Nile perch in Lake Victoria, led to the
extinction
of many native Cichlid species
Overexploitation - humans harvesting plants and animals
too fast to
replace
- ex: Atlantic Cod, Minke Whale, Bison
Disruptions of food chains the extinction of one species can doom
other
members of its trophic chain
