In landscape ecology, the matrix is the area surrounding a habitat patch. The matrix can affect a species living in the habitat patch by altering: O A. Dispersal between patches O B. The availability of resources O C. The abiotic environment in patches D. Our appreciation of Keanu Reeves' acting skills O E. A, B and C are correct

An ecologist studying the availability of nutrients and the distribution of the plants that live in this habitat is working at this level. An ecologist studying the size and distribution of the Karner blue butterfly is working at this level. An ecologist studying the mutualistic relationship between the Karner blue butterfly and ants is working at this level. An ecologist studying behavior of the caterpillars when they are at different larval stages is working at this level. < Previous a Choose ] [Choose ] Community Organismal Ecosystem Population ThouT [Choose ] [Choose] No new data to save.

When substances are not broken down in metabolism but stored and passed on to higher trophic levels which of the following processes occurs? Group of answer choices a. Predation b. Coevolution c. Ecological Succession d. Biological Magnification e. Competition

T or F Edge habitat always provides differential access to one habitat type when resources are spatially separated.   Birds nesting in edge habitats can be exposed to increased rates of nest predation.   Edge habitats often become intermediate between the two adjacent habitats   The three general mechanisms by which edge habitats can become different from core habitat include abiotic factors, access and species interactions.

Habitat fragmentation results from human activities that change large blocks of landscape, leading to many negative effects on species and ecosystems. Which of the following is not one of the possible consequences of fragmentation? A. reduction of available habitat O B. increasing degradation of habitat patches C. increasing wind speeds and temperatures at patch edges D. spatial isolation of patches E. increase in top predators present in patches

23. Wayne Sousa glued small boulders in place within an intertidal boulder field in Santa Barbara and discovered that ...   a. low disturbance frequency resulted in a community composed of a mix of r and K-selected species b. low disturbance frequency resulted in a community composed of K-selected species c. species diversity was highest where disturbance frequency was high d. moderate disturbance frequency resulted in a community composed of r-selected species e. species diversity was highest when disturbance frequency was low

I’m having hard time which outcome would best fit the question can you please help?

1) Compare the biodiversity indices to one another. State a claim about the effect of pollution on the biodiversity of the stream ecosystem. Describe how the pollution levels affect the species richness and biodiversity of the stream. Justify your claim with evidence. Describe the difference in species richness you observed. Explain how human intervention can change biodiversity in positive ways.

What is the difference between a community and an ecosystem? Group of answer choices a. an ecosystem includes the abiotic environment b. a community includes the abiotic environment c. they are exactly the same thing d. an ecosystem covers a larger geographic area e. a community covers a larger geographic area

Match the following definitions or descriptions of community ecology to the most appropriate vocabulary word A model where there is a unidirectional influence from lowe to higher trophic levels A model where predation mainly controls community organization. An event, such as a storm, fire, flood, drought, or human activity, that changes a community by removing organisms from it or altering resource availability. ✓ [Choose ] top-down model disturbance A term which describes most communities as constantly changing after disturbance Occurs in a virtually lifeless area where soil has not yet formed, such as on a new volcanic island or on the rubble left by a retreating glacier Occurs when an existing community has been cleared by a disturbance that leaves the soil intact secondary succession bottom-up model nonequilibrium model primary succession [Choose ] [Choose ] [Choose ] [Choose ] + +
