Flashcards about Communities and Interactions based on lecture notes.

Why do zebras and gazelles exhibit herding behaviors?

To protect the group from predators.

Eastern cottontail rabbits are commonly found eating grass, leafy greens, and shrubs. They are best described as:

What abiotic limiting factors could a scientist study to see how environmental factors negatively impact the survival of a population?

Amount of sunlight, Frequency of drought, Temperature changes

Chipmunks run to take cover when a hawk circles in the air. To the hawk, the chipmunk is:

Its prey

What is the relationship between coral and seagrasses when seagrasses overgrow coral, causing reef damage?

Competition

In a food web, which organisms are carnivores?

A decrease in the number of mountain lions in a food web would most likely result in an increase in the number of:

Deer

In a food web, the rabbit is:

Prey to the mountain lion

If a new disease enters an ecosystem and causes the shrew population to decrease dramatically, what population changes would most likely occur?

Snakes would eat more rabbits, which could lead to a decrease in the rabbit population.

Which type of graph would best display data collected over a four-month period to show change over time?

According to a predator-prey graph, what is the most likely reason the predator population increased from day 6 to day 8?

The prey population was high on day 6.

Oxpeckers land on a rhinoceros to eat ticks and parasites. The birds get food, and the rhinoceros gets pest control. What type of symbiotic relationship is this?

Mutualism

Which is an example of competition that would most likely occur in nature?

Chimpanzees fighting over territory or a mate

Which are examples of populations?

Red foxes in a forest, Grasses and flowers in a park, Vampire bats living in the same cave, Emperor penguins living on Antarctic ice

Commensalism

What is the honeybee's niche?

In an aquatic food web, which statements are most likely correct?

Seagulls and seals will compete with each other for some food sources, Squid are prey for penguins.

If too many krill are caught due to overfishing, what is most likely to occur in an aquatic food web?

The seals would eat more penguins and squid.

Which animal, if removed from an aquatic food web, would have the greatest effect on the competition between the seagull and seal populations?

Squid

A tick attached to the skin under a dog's fur, feeding on its blood and potentially giving it Lyme disease, represents what type of symbiotic relationship?

Parasitism

What is the term for organism that benefits in the symbiotic relationship depicted.
