APES Biodiversity Review (Miller Ch.4)

Number of different species &the number of individuals of each species combined in an ecosystem

The ability of one or more organisms in a population to tolerate a chemical designed to kill it

T or F:Shifting continents changed the global climate and changed where organisms could survive

The model that shows the evolution and diversity of life on Earth is called the ______

Type of organisms have narrow niches, only live in one type of habitat or eat one type of food.

The distinct role that each species has in an ecosystem is an ecological

When individuals with a desired trait have more offspring than other members of the population

Species that provide early warnings of damage to a community or ecosystem

The theory of evolution is supported by all these types of evidence EXCEPT...

___________ enables life on Earth to adapt to and survive dramatic environmental changes

The second phase of speciation is...

Which trait did NOT allow humans to become such a powerful species?

The variety of processes such as nutrient cycling and energy flow within ecosystems

True or False: Survival of the fittest means the physically strongest organisms survive.

A non-native species that takes over or otherwise damages native species' niches and habitat.

The normal, low rate of the disappearance of species

Scientists have identified about how many of the Earth's species?

What geological concept(s) is illustrated in this animation?

T or F: Plate movement allows organisms to move, adapt to new environments and form new species

The relative abundance of each of those species in an ecosystem

This concept covers Earth's variety of deserts, grasslands, forests, mountains, oceans,lakes...

An example of a local endemic species is...

When environmental conditions change, organisms face 3 possible futures.Which ISN'T one of them

Species who play vital roles and whose disappearance would cause an ecosystem to collapse.

A species with broad niches that can live in a variety of places or eat a variety of foods.
