Base your answer to the following question on the

following statement and on your knowledge of

biology. The gene pool of a large population of

organisms living on an isolated island was analyzed

for gene frequencies. The population used for the analysis consisted of all

All the plants and animals interacting in a given area

make up a

• community

• population

• biosphere

• species

Two species of animals with a similar appearance

live in the same habitat but do not compete for food.

This is because they most likely

• reproduce at different times of the year

• are the same size

• occupy different ecological niches

• are active at night

Which sequence of organisms represents a food chain within this food web?

• tadpoles -> algae -> daphnia -> back swimmers

• sedges -> ants -> frogs -> kookaburras

• algae -> daphnia -> decayed material -> bacteria

• dragonflies -> sedges -> ants -> centipedes
