On the Living World — Chapter Concepts

To assign organisms fixed labels independent of new evidence

To organize organisms by evolutionary relationships and shared traits

To rank organisms by how useful they are to humans

To list every species in alphabetical order for record keeping

A chart showing only species numbers per habitat

A representation of energy transfer and biomass across feeding levels

A seasonal calendar of reproductive cycles

A classification of mutualistic relationships only

Its potential to disrupt native species and food webs

The number of humans who will like the species

Its exact genome sequence compared to all other species

Whether it can survive only in laboratory conditions

Diverse species provide resilience and multiple functions like pollination and nutrient cycling

Fewer species always mean more efficient ecosystems

Ecosystem services are unaffected by species interactions

Biodiversity only increases scenic value, not ecosystem functions

Any trait acquired during an individual's lifetime

A heritable trait that increases an organism’s fitness in a given environment

A random trait that always becomes universal quickly

A behavior taught to all species in a community

By predicting genetic mutations each species will have

By listing only physical shelter options in an area

By defining resources and conditions a species needs, showing potential overlap and competition

By ranking species by attractiveness to predators

Limiting habitat destruction and reducing high-risk wildlife contact

Increasing global wildlife trade without regulation

Avoiding all vaccinations in livestock

Only monitoring water quality in cities

It guarantees immediate population growth regardless of conditions

It ensures every individual looks identical to predators

It prevents any mutations from occurring

It provides raw material for adaptation to changing environments and disease pressures
