Predict how species diversity would change if sea otters disappeared from kelp forests. O A Diversity would Increase because invertebrate species could multiply without predation. O B. Diversity would not change because another predator would fill the niche left by the sea otters O C. Diversity would increase because other species would move into the kelp forests to fill the niche left by the sea otters. D. Diversity would decrease due to the sea urchins consuming the kelp and removing an essential habitat for other species.

Suppose a team of scientists uncovers a new species of small, predatory mon deep in the jungles of South America. To better understand the organism's history, each member of the scientific team investigates a different aspect of the animal's ecology. Identify the type of ecological system this researcher is studying: Beverly investigates how interactions between the mammal species and different types of prey influence the amount of available phosphorous in the area. O community ecosystem O individual

Which of the following statements related to classifications of rarity and extinction is TRUE? A species with an extensive geographic range and large local populations cannot be vulnerable to extinction. O Once species are the list of endangered species, they can never recover. O Species that are the most vulnerable to extinction have small population sizes, broad habitat tolerances, and narrow geographic ranges. O The majority of bird species that have gone extinct were those restricted to islands.

Why are species that live at the tops of mountains at increased risk of extinction due to climate change?   a. The colder temperatures at the tops of mountains gradually increase, and the species at the tops of the mountains are displaced by species at lower elevations moving up.    b. The species at the tops of the mountains are adapted to moving up and down the mountains and species at lower elevations are displacing them as they move down the mountains.    c. The species at the tops of the mountains are adapted to lower oxygen and climate change increases oxygen content in the air.    d. Species at the tops of mountains do not have the genetic diversity for adaptation that lower-elevational species do. Therefore species at the tops of the mountains are more likely to go extinct.

Where would be the best place in Polk County to see a shrub bog? Select one: a. Tiger Creek Preserve b. Avon Park Air Force Range c. Catfish Creek Preserve d. Lake Marion Creek Wildlife anagem Area O e. Marshall Hampton Reserve Cypresses have structures called that grow up from their roots and may help them obtain oxygen. Select one: a. haloes b. strands O c. buttresses d. point bars e. knees What ecosystem grows on old dunes that are no longer being moved by the wind? Select one: a. maritime hammock O b. coastal berm c. coastal grassland d. shell mound e. coastal scrub

9 According to the text and figure 2, which statement accurately describes relationships among variables in the SAVANNA model? A. Predation is directly affected by bison distribution and weather.   B. Plant population is directly affected by water, fire, and bison population.   C. Bison distribution is directly affected only by weather and predation.   D. Bison population is directly affected only by predation and hunting and culling.

D Question 2 Tasmanian devils became extinct on the mainland of Australia probably because of competition for resources with dingo O The two species are both herbivores O The two species evolved to eat different prey species. The two species' niches were very similar. O The interaction between the two species was mutualism.

Two islands in the Pacific Ocean are of equal size but differ in their distance from the mainland. Island C is 5 km from the mainland, while Island D is 50 km away. According to island biogeography theory, how would the extinction rates on these islands compare and why? Group of answer choices: A. Island D would have higher extinction rates because its greater distance from the mainland makes it harder for species to recolonize after local extinctions, reducing species turnover B. Both islands would have similar extinction rates because island size, not distance from the mainland, primarily determines extinction rates C. Island C would have lower extinction rates due to its smaller distance from the mainland, allowing easier recolonization and rescue effects D. Island C would have higher extinction rates due to its proximity to the mainland, which increases competition and predator pressure from mainland species

slands are well known for having many endemic (unique) species. What is a likely explanation for this pattern?   A. Humans bring partly or fully domesticated species with them when they arrive on islands.   B. Colonizers encounter fewer competitors on an island, so they can diversify.   C. Islands are more complex habitats than continents are, so they have more niches for specializations.   D. Colonizers are likely to have more diversity than local populations and thus outcompete them.   E. The type of organism that is a good colonizer has more than the average amount of genetic variability, so it's more likely to speciate.
