Biodiversity

Globally, the leading cause of biodiversity loss is 

• invasive species
• poaching and overharvesting
• pollution
• habitat change and loss 

What is the difference between biotic and abiotic?

• Biotic are non-living things

• Abiotic are living organisms

• Biotic is life,

  Abiotic is non-living

• Biotic is non-living, Abiotic is living

Emphasizing the preservation of entire ecosystems will

• cause the economic needs of farmers to suffer in order to save a single species.

• decrease biodiversity, especially in tropical rainforest.

• throw the food webs of many ecosystems out of balance.

• save many unknown species from extinction.

What does biodiversity mean?

• Only one species in an area.

• The different amount of species in an area

• All abiotic life

• Nitrogen fixation

Some species are so important to the functioning of an ecosystem that they are called

• keystone species

• threatened species

• endemic species

• hybrid species

What does this picture represent?

• species diversity
• ecosystem diversity 
• genetic diversity
• biodiversity

Pollution is one of the five threats to biodiversity.

• TRUE
• FALSE

What is the most impactful cause of biodiversity loss world wide?

• habitat loss
• pollution
• invasive species
• overharvesting

An endangered species is

• a plant growing on public land

• a species in danger of extinction

• a species that has disappeared entirely

• an organism brought to a place where it has never lived before

Why is biodiversity important in fighting disease in food crops?

• It prevents one disease from wiping out an entire food crop.
• It prevents habitat loss of native species.
• It provides different foods for different populations.
• It prevents fungal disease from wiping out corn crops.
