What do the arrows indicate in a food web?

Where the energy is being transferred

Suppose that a llama is hit by a truck and dies. Where will most of the biological matter in the llama go next?

To the soil to be used by plants

To first order consumers that might eat the llama

To microorganisms that decompose and recycle matter

What happens to 90% of the energy in each trophic level?

It is used for metabolic processes

All of the energy is used and none of it moves to another level

the change in characteristics/traits of a species over a long period of time (many generations)

errors in an individual's genetic code (DNA) that leads to changes in the genotype and/or phenotype of that organism

shifting of traits to better align with the environment

anatomy that supports common ancestry (homologous, analogous, and vestigial)

the development of a new species

the study of the distribution of organisms

when two different species mate and create a new species

when certain traits are favored by the environment and increase in frequency

Where do adaptations come from?

Both mutations and genetic recombination are sources of adaptation

The individual organism decides to adapt

Mutations that give an organism an advantage in its environment

Genetic recombination during meiosis

Two organisms that are closely related would have

completely different DNA sequence

In this example of natural selection, what environmental factor is acting as a selection force - or environmental pressure - on the giraffe?

Having spots that act as camouflage

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

The function of these bones is the same in all animals

They live in similar environments

a group of the same species in the same geographic area.

a group of similar species in different areas

a group of several species in the same geographic area

a group of several species along with their abiotic factors in a small area.

Researchers studying medium ground finches on the island of Daphne Major in the Galapagos Islands collected the data below on the survival rates of finches with different sized beaks over a three-year period that included a drought. Which statement about the finches in this environment is best supported by the data?

Finches with large beaks are more fit for the environment than finches with small beaks are

Finches with large beaks had more genes than the other finches did.

Finches with small beaks reproduce more quickly than finches with large beaks.

Finches with medium beaks had more mutations than the other finches did.

the movement of genes into or out of a population

Random chance; small population

A sudden change in one or more characteristics due to a change in a gene

Occurs due to physical difference as a result of a genetic difference

The movement of organisms from one place to another

Which answer is true regarding biodiversity?

An ecosystem is healthier when the biodiversity is great.

As long as there are enough producers, an ecosystem is considered to have a good amount of biodiversity.

The rain forest has an unhealthy ecosystem because its biodiversity is too great.

Biodiversity is positively affected when non-native species are introduced into an environment
