FINAL 01 - Biodiversity and the Healthy Society Flashcards
A common measure of biodiversity is called __________
Species richness
Refers to the vast variety of life forms in the entire Earth
Biodiversity
Refers to variations among organisms of the same species; these variations are usually passed down from parents to offspring (Types of biodiversity)
Genetic biodiversity
Refers to a variety of species within a particular region; this is influenced by the environmental conditions in the region (Types of biodiversity)
Species biodiversity
Refers to a network of different species in an ecosystem and the interaction of these species (Types of biodiversity)
Ecological biodiversity
Major contributing factor is the inhabitation of human beings and the use of land for economic gains (Threats to biodiversity)
Habitat loss and destruction
Alterations and sudden changes, either within species groups or within the environment, could begin to change entire ecosystems (Threats to biodiversity)
Alterations in ecosystem composition
Overhunting, overfishing, or over-collecting of species can quickly lead to decline of biodiversity (Threats to biodiversity)
Over-exploitation
Can cause irreversible damage to species and varieties (Threats to biodiversity)
Pollution and contamination
Can cause biodiversity loss; species and populations may be lost permanently if they are not provided with enough time to adapt to changing climatic conditions (Threats to biodiversity)
Global climate change
Disease caused by parasitic worms
Schistosomiasis
3 parasitic worms that can cause schistosomiasis (SM, SH, SJ)
Schistosoma mansoni, Schistosoma haematobium, Schistosoma japonicum
__________ can have a serious impact on human health and it could deteriorate farming systems and reduce nutrients in some foods
Climate change
