• a wide variation of traits

• the ability to pass on traits to offspring

• the ability to inherit traits from parents

• genes that code for traits

The study of biomes most closely relates to the study of ____.

• genetic diversity

• ecosystem diversity

• species diversity

• ecosystem services

• pollination

The greatest benefit of species diversity is that ____.

• it tends to lead to more stable ecosystems

• it creates more ecological niches for species to occupy

• it reduces competition among species for resources

• functional diversity is lower when species diversity is high

• it can help species adapt more successfully

Earth’s variety of deserts, forests, and grasslands are all examples of __________ biodiversity.

• biome

• ecosystem

• species

• genetic

• functional

Ecosystems with a high level of species diversity tend to be more ____________ in the event of environmental changes.

• fragile

• likely to fall

• resilient

• noisy

• dangerous

NGSS.MS-LS2-5

Ecosystems that are biologically diverse are more likely to include species with traits that enable them to adapt to changes in the environment, such as disease or drought. Such species could help an ecosystem maintain its resilience even if other species are lost.

This statement describes:

• the endangered species act

• the four types of biodiversity

• generalist vs specialists species

• the insurance hypothesis

• keystone species
