In the rocky intertidal zone, two barnacle species are found, one low down in the wet zone and the other higher up in the dry zone. Let's call them WET and DRY. Which of the following statements is true? The fundamental and realized niche of DRY are identical. The fundamental niche of WET is smaller than its realized niche. The fundamental niche of DRY includes the wet zone (where it doesn't occur in nature). The fundamental niche of WET includes the dry zone (where it doesn't occur in nature).

Which species is the stronger competitor for space in the intertidal zone? O Chthamalus Balanus

Which of the following organisms would you expect to be most abundant in the tall grass prairie ecosystem?         Bobcats and and coyotes       White-tailed deer and cottontail rabbits       Harriers and and kestrels       Grasses and flowering plants

The competitive exclusion principle is best defined as   Multiple Choice   the competition among individuals of the same species in the same location.   the principle that two species that occupy the same niche cannot coexist indefinitely.   an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual.   the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.

Temperate grasslands have very seasonal temperature and rainfall. Summer can be hot and a bit wet, while winters can be cold and dry. Because of these conditions, you would expect temperate grassland species to have.. Narrow fundamental niches Wide fundamental niches

which of the following statement is false: -The two major compounds in the atmosphere that are responsible for acidic precipitation are sulfuric acid and nitric acid.  -Evolution in a parasite from ectoparasitism to endoparasitism would most likely be caused by an increase in the number or intensity of natural enemies of the parasite.  -A fundamental niche is often not realized because no one species has exclusive access to all the resources within its fundamental niche.  -Competition is often an important driver of early succession, while facilitative interactions tend to play a more dominate role later in succession.

The population of trout in a lake has significantly declined over the past year. The main source of food for the fish in this lake are aquatic insects. Due to poor climate conditions, there are significantly fewer insects and thus, not enough food to sustain the population of trout in the lake. Trout is a food supply for larger fish in the lake and without enough trout, other fish are negatively impacted in the lake. How does climate change cause a problem for the lake in this scenario?

Describe three kinds of benthic marine communities that use hard sub-strates and three that use soft substrates. What are the main physical factors that separate community types within each substrate category?

A group of golden lion tamarins were released into their natural habitat but most did not survive. The researchers found most were very underweight, presumably due to a lack of food availability. Using the information provided above, What is a possible solution to this human impact problem before releasing more tamarins into this habitat?

Desert rodents and ants both depend on seeds from scrub plants as a food resource. What conditions would favor the existence of both species within the biological community? Rodents prefer larger seeds as a food choice, while ants tend to consume smaller seed types. Rodents and ants inhabit different areas of the habitat based on temperature and rainfall patterns in the environment. Foraging rodents are more efficient at gathering food resources in the desert habitat than the foraging ants. An increase in rodent predators in the biological community causes a dramatic increase in the size of the ant population.
