Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.
Q. Which area would have the most species diversity?
Species diversity is greatest in the tropics, particularly in tropical forests and coral reefs. The Amazon basin in South America has the largest area of tropical forests. The southwestern Pacific has the greatest diver- sity of coral reef species.
Q. Which region would likely have the greatest amount of biodiversity?
The Amazon rainforest is a tropical rainforest with the world’s largest biodiversity (it has more species than the rainforests of Africa or Asia).
Q. What is a natural factor that would most likely decrease the ecosystems biodiversity?
The source of sunlight is the main source of energy and if there will be more sea weed trapping sunlight then there will be a competition between seaweed and coral reef. So, the natural reason for the decreased biodiversity is overgrowth of population of seaweed which prevents the light from reaching the reef.
Q. Which ecosystem would most likely recover the fastest?
Based on the information, which ecosystem would most likely recover the fastest from a natural disruption? Ecosystems with more genetic diversity and larger number of different species are more likely to recover from natural disruptions.
Q. Which of the following is most likely to cause an ecosystem to become unstable?
the ecosystem will become unstable because predators will have fewer prey, the birds will have fewer nesting sites, and the area downriver will become vulnerable to flooding without the burrows to aerate the soil and provide drainage for monsoon rains.
Q. What happens in an ecosystem as biodiversity increases?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
Q. What causes change to ecosystems?
4.1 Natural or human-induced factors that change ecosystems are called drivers. Habitat change and overexploitation, for instance, are direct drivers that influence ecosystem processes explicitly. 4.3 Important direct drivers include: habitat change, climate change, invasive species, overexploitation, and pollution.
Q. How changes in environmental conditions can affect both individuals and ecosystems?
Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought.
Q. Who believed that as animals became more complex so did their emotions?
Carolus Linnaeus
Q. What helps keep the snake and rodent population in check in a particular area?
A scavenger that cleans up the environment by ingesting dead animals. Helps to keep the snake and rodent population in check in a particular area. Is a filter feeder.
Q. What is the study of animals structures behaviors functions and evolution?
Ethology is a branch of zoology—the study of animals’ structures, behaviors, functions, and evolution.
Q. Which statement best describes energy of an ecosystem?
The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat. – best describes energy of an ecosystem.
Q. Which statement best describes what happens to energy and molecules in ecosystems?
Which statement best describes what happens to energy and molecules in a stable ecosystem? Energy is continuously added to the ecosystem and molecules are recycled.
Q. Which of the following best describes the role of autotrophic organisms in ecosystems?
These are the necessary reactants for the process of photosynthesis. Which of the following best describes the role of autotrophic (self-feeding) organisms in ecosystems? They consume other organisms for energy. They produce their own inorganic molecules, which can be broken down for energy.
Q. Which statement best describes how matter moves within and between ecosystems?
Which statement BEST describes how matter moves within and between ecosystems? Matter flows in a one-way direction through food chains and food webs.
Q. What is it called when nutrients move through an ecosystem?
Nutrients move through the ecosystem in biogeochemical cycles. A biogeochemical cycle is a circuit/pathway by which a chemical element moves through the biotic and the abiotic factors of an ecosystem. It is inclusive of the biotic factors, or living organisms, rocks, air, water, and chemicals.
Q. How does the way that matter flows through an ecosystem?
How does the way that matter flows through an ecosystem differ from the way that energy flows? Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Why do living organisms need nutrients? Every living organism needs nutrients to build tissues and carry out essential life functions.
Q. How does matter flow in an ecosystem?
Next, energy and matter move up the trophic levels of an ecosystem as producers are eaten by primary consumers, which are then eaten by secondary consumers, and so on. Dead producers and consumers and their waste products provide matter and energy to decomposers.
