NEED BIOLOGY HELP PLEASE ASAP!?

• 1)High biodiversity often helps make an ecosystem more A. susceptible to disease. B. resilient. C. competitive. D. challenging to survival. 2)What happens in a food chain if one of the lower consumers is eliminated or reduced in numbers? A. There is little effect B. The whole food chain dies out C. Those higher in the food chain must find alternate sources of food; those lower in the food chain must be controlled by other consumers D. Those higher in the food chain benefit; those lower in the food chain suffer 3)As a population reaches its carrying capacity, resources become more scarce. Which of the following would increase within the population? A. available shelter B. nesting sites C. competition D. birthrate 4)Which of these activities causes the greatest loss of biodiversity? A. habitat destruction B. air pollution C. water pollution D. soil erosion 5)As the density of a population increases, the effects of starvation and disease also often increase. These are which kind of factors? A. abiotic B. symbiotic C. density-dependent D. density-independent 6)Which two key factors determine the climate of a region? A. soil type and day length B. temperature and precipitation C. organism types and bodies of water D. biodiversity and habitats 7)Natural selection is the process by which A. organisms with traits well-suited to their environment reproduce at a greater rate than less well-adapted organisms in the same environment. B. change occurs in the genetic characteristics of individuals that live together in an environment from one generation to another. C. baseball players pass on the trait for strong arm muscles to children. D. use and disuse of a characteristic leads to evolutionary change. 8)Linnaeus's two-word system for naming organisms is called A. binomial nomenclature. B. taxonomic evolution. C. Genus species. D. Greek polynomials. 9)Temperatures on Earth may continue to increase because A. decomposers essential to recycling matter are being destroyed. B. increasing carbon dioxide in the atmosphere will trap more heat. C. too much oxygen is now given off by plants. D. Earth tilts toward the sun in the summer. PLEASE HELP ASAP! THANKS

• Answer:

  Do you trust a random stranger on the internet with your grade? I haven't read your textbook so I am going to just guess. 1)High biodiversity often helps make an ecosystem more B. resilient. Note that this is true of the ecosystem as a whole. A climax community that has existed a long time may be composed of a lot of specialist species, and the specialists are fragile. 2)What happens in a food chain if one of the lower consumers is eliminated or reduced in numbers? C. Those higher in the food chain must find alternate sources of food; those lower in the food chain must be controlled by other consumers ...and note here that I've assumed for this answer that the eliminated population was not a "keystone species" in this ecosystem. 3)As a population reaches its carrying capacity, resources become more scarce. Which of the following would increase within the population? C. competition 4)Which of these activities causes the greatest loss of biodiversity? A. habitat destruction 5)As the density of a population increases, the effects of starvation and disease also often increase. These are which kind of factors? C. density-dependent 6)Which two key factors determine the climate of a region? B. temperature and precipitation 7)Natural selection is the process by which A. organisms with traits well-suited to their environment reproduce at a greater rate than less well-adapted organisms in the same environment. Note: I considered and rejected option B, which better describes "evolution." 8)Linnaeus's two-word system for naming organisms is called A. binomial nomenclature. 9)Temperatures on Earth may continue to increase because B. increasing carbon dioxide in the atmosphere will trap more heat. Note: Global warming is real, but the cause is somewhat controversial. Warming on Mars suggests that the sun is going through a phase of greater production of radiation. http://news.nationalgeographic.com/news/2007/02/070228-mars-warming.html
