Which of the following is a habitat and way of life to which a particular organism is adapted?

2

Giraffes use their incredibly long necks and tough, prehensile tongues to expertly remove acacia leaves from their spiky branches. Honey badgers are opportunistic and will chase other predators away from carcasses to eat carrion. They will also destroy beehives with their huge claws to reach honey. Additionally, they can use their claws to dig burrows and find yams. Gerenuks will stand on their back legs to reach the tops of grassland shrubs, which is a unique trait among grass eating antelope. Last, aardvarks have immense nails and sticky tongues that they use to open termite mounds and consume thousands of termites and ants in a given night.

Using this information, which of the following species would best be described as a niche generalist?

3

A group of species that share common food sources avoid competition by living in different locations. Of which of the following is this an example?

4

Niche Theory allows us to understand the role a species plays in its environment. Niche Theory includes a species home range, life history, mating patterns, food sources, and many other characteristics. Which of the following terms is used to describe the whole range of areas a species can occupy within its environment?

5

Every species has a different range of habitat in which it can exist. A healthy species that is found only in a specific region (i.e. Hawaii) is said to be __________ to that region.

6

A species' __________ is its unique role and position in its ecosystem.

7

Some plant species require their seeds to be "activated" by high temperatures, and only sprout after a forest fire. Given this, where in the succession must these species be placed?

8

Individuals who are better-adapted to a certain environment are more likely to survive and reproduce; thus increasing the the proportion of those individuals in a population. This process is called natural selection.

Over time, natural selection can result in a population specializing to form what?

9

The process by which species are driven into different niches by availability of resources is called __________.

10
