Question 1

Which of the following best describes the relationship between the predator and prey shown in the first image (a fish eating another fish)?

Accepted Answer

Predation, because one species benefits by killing and eating the other.

Question 2

Which of the following is an example of a foundation species in a coral reef community, as shown in the second image?

Accepted Answer

Coral, which provides habitat and food for many other organisms.

Question 3

In the context of community ecology (third image), which of the following best describes the focus of this field?

Accepted Answer

The study of interactions between species and factors affecting the number, type, and abundance of species in a community.

Question 4

The cartoon in the fourth image shows several animals interacting. Which interaction is an example of interspecific competition?

Accepted Answer

A monkey eating a banana while a baboon chases it away.

Question 5

The image of two kangaroos fighting (fifth image) is an example of which type of competition?

Accepted Answer

Intraspecific competition

Question 6

Based on the sixth and seventh images, which of the following best distinguishes intraspecific from interspecific competition?

Accepted Answer

Intraspecific competition occurs within the same species, while interspecific competition occurs between different species.

Question 7

Refer to the population density graph of Paramecium aurelia and Paramecium caudatum (eighth image). What ecological principle does this experiment demonstrate?

Accepted Answer

Competitive exclusion principle

Question 8

The images of lizards occupying different parts of a tree (ninth and tenth images) illustrate which ecological concept?

Accepted Answer

Resource partitioning

Question 9

In the barnacle experiment (eleventh image), what is the difference between the fundamental niche and the realized niche?

Accepted Answer

The realized niche is the area actually occupied by the species, while the fundamental niche is the area it could potentially occupy.

Question 10

The beak depth distributions of finches (twelfth image) on different islands illustrate which evolutionary process?

Accepted Answer

Character displacement

Question 11

Which of the following best describes the interaction between a lion and a zebra, as shown in the predation image (thirteenth image)?

Accepted Answer

Predation

Question 12

The image of a cheetah chasing a gazelle (fourteenth image) is an example of which type of interspecific interaction?

Accepted Answer

Predation

Question 13

The canyon tree frog blending into its environment (fifteenth image) is an example of which type of adaptation?

Accepted Answer

Cryptic coloration

Question 14

The stick insect camouflaged among leaves (nineteenth image) is using which type of defense mechanism?

Accepted Answer

Question 15

The poison dart frog with bright colors (twentieth image) is an example of which type of adaptation?

Accepted Answer

Aposematic coloration

Question 16

The nonstinging syrphid fly mimicking a stinging bee (twenty-third image) is an example of which type of mimicry?

Accepted Answer

Batesian mimicry
