Speciation, Cladogram, Food Web Quiz

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?

• gametic isolation
• geographic isolation

The process by which one species becomes two is called:

• temporal isolation

• geographical isolation

• speciation

• evolution

In a worm population, there are two variations. One type of worm likes to live in the acidic soil, and one type of worm likes to live in basic soil. This reduces the likelihood that they will reproduce. Eventually, the two worms become two different species.

• geographical isolation

• ecological isolation

• behavioral isolation

• reproductive isolation

In a population of mice, there are long-tailed mice and short-tailed mice. The long-tailed mice only mate with the long-tailed mice and the short-tailed mice only mate with the short-tailed mice. This reduces the likelihood that they will reproduce with each other. Eventually, they become two different species.

• behavioral isolation

• reproductive isolation

• geographic isolation

• temporal isolation

In order to be a species, organisms:

• need to be the same size and color

• need to be able to produce fertile offspring

• need to be able to produce offspring

• need to be be in the same location

A population is a group of organisms:

• of the same species in the same place at the same time

• of related species in the same habitat

• who share a common ancestor

• who are close to each other on a cladogram

• hair

Check all the traits that a lizard and a human have in common.

• jaws
