habitat loss Flashcards
an ecosystem is more likely to be sustainable if there is more…
biodiversity
what can biodiversity mean
- many different species
- differences within a species
- number of ecosystems
what are the four main changes in biodiversity
- habitat fragmentation
- habitat loss
- habitat degradation
- habitat destruction
example of habitat destruction
clear cutting
WHAT is habitat fragmentation
what an ecosystem of habitat is broken into isolated fragments
fragmentation happens when
parts of a habitat are destroyed, leaving behind smaller unconnected areas.
why is fragmentation a big deal
because animals won’t move from one section to. another I fear of predators and part of habitat is destroyed
when does habitat loss occur
When it is converted to other use
Examples of habitat loss
A wetland is filled
a prairie is covered by housing
forest cut down for development
what is habitat degration
when habitat is so diminished in quality that species can’t survive
why can urban development degrade a habitat
Urban development can degrade a habitat because plants and soil or replaced with ash fault and concrete
Examples of urban development degrading a habitat
- water runs off instead of soaking in
- temperature rises because asphalt and concrete absorb more heat
what is habitat destruction
when the whole habitat is destroyed
what is the main cause of habitat destruction
agriculture
what is pollution
the contamination of air, water or land
