which of the following best explains how environmental stressors such as wildfires can affect biodiversity in an ecosystem

ecosystems with more species diversity are more likely to recover after a disturbance and ecosystems with low species diversity

which of the following best describes a supporting ecological service provided by wetlands

wetlands provide a habitat for a wide variety of organisms

A1 Hector pond is sampled in early September the sample yields one small catfish as well as 17 benthic in verb of invertebrates that represent 10 species which of the following can be estimated from the sample for the invertebrates in the pond

The species richness

which of the following best identifies the authors claim

aardvarks are keystone species and their decline would have a trophic cascade effect on the ecosystem

The money, finch species of the Galapagos islands of all from a single species are immigrated to the island from the coast of South America, the species different, primarily in big shape, which is closely related to the type of food, each species specializes in eating, which of the following best explains why each of the finch species on the Galapagos islands evolved to be specialists?

Islands have limited food resources, forcing species to feed on a small range of food items

based on the theory of island biogeography, which of the following is most likely reason, then island in the ocean is 5 km from a continent or have a higher number species than one that is 15 km from a continent

there are more species that have the ability to travel 5 km than can travel 15 km

A one hector pond is sampled in early September the sample yields one small catfish, as well as 17 beneath invertebrates that represent 10 species if the pond is resample the year later, which of the following would best indicate that the pond I’ve been adversely affected by adjacent development

The biodiversity of the pond has decreased

highly specialized species tend to evolve on islands because of the environmental conditions and resource availability based on the theory of island biogeography, which of the following would most likely experience the greatest decline of a specialist species, if an invasive species emerge from the mainland

A small island in close proximity to the mainland

at which time after clear cutting does the ecosystem exhibit the greatest species richness

100 years

based on the data shown in the graph, which of the following best describes how ecological list could determine when this ecosystem is approaching a climax community

Record the number and type of producers present every year after the eruption

The devils hole pupfish is one of the worlds rarest fish is spending most of its time in the top view. Meters are very warm waters of a cavern located in the middle of the Mojave desert devils hole, El Chico, logical pool is the only naturally occurring habitat for the endangered, devils hole, port fish the fish is habitat is one of the smallest natural ranges known for any vertebrate. Devils hole is an extreme environments with water temperatures and dissolved oxygen concentration. You’re the lethal limits for most fish species, which of the following statements, best explains why the devils hole Paul fish are able to live in this environment.

The pup fish are well adapted to the habitat of devils hole, and can thrive in conditions that are outside of the range of tolerance for most other species

based on the data shown in the graph, which of the following events occurred after the glacial retreat

primary succession

which of the following best describes the role of moss in the transition stage three of the process

it breaks down rock and adds organic nutrients to the soil

which of the following is the best example of a keystone species

see otter

which of the following best shows the process of evolution

population of mosquitoes develops resistance to a pesticide

which of the following statements correctly describes a trend seen in the data?

The lowest sea level occur during the Paleogene period
