D.A warming event causing species to become smaller has never happened before.答案:A 细节理解题。根据第四段最后一句“There is a recent report on warmer temperatures' negative effects on plankton, the base of the marine ecosystem.”可知,气候变化已经对浮游生物产生了有害影响。故A项正确。20.What...
like fishing.There are fish and snails that eat starfish, particularly the giant triton snail, which is the main predator of the starfish.These fish and snails have themselves experienced a decline in population because of overfishing by humans.So with a decline in starfish predators, the starfish...
And here's what's so fascinating: as more and more fishing vessels with better and better fishing technology were competing for cod, this competition was causing changes to the biology of the fish and these changes were making it more and more difficult for the cod population to sustain itsel...

Species can also be threatened by genetic pollution – uncontrolled hybridization and gene swamping. For instance, abundant species can interbreed with rare species, thus causing swamping of the gene pool. Overexploitation is caused by activities such asoverfishing,overhunting, excessive logging andilleg...
Natural disasters create temporary cost-push inflation by damaging production facilities. That's what happened to oil refineries after Hurricane Katrina.10In general, the depletion of natural resources is a growing cause of cost-push inflation. For example, overfishing has reduced the supply of seafoo...
B.Dark colored surfaces reflect the sun’s heat, causing air temperatures to rise C.Because urban surfaces absorb heat, air and surface temperatures increase D.Rising ambient air temperatures lead to urban surfaces absorbing more heat2. Which of the following is not a cause of the urban heat ...
What is the importance of biodiversity? How are habitat loss and biodiversity connected? How does conservation affect biodiversity? How does biodiversity loss impact the rate of decomposition? How can biodiversity affect an ecosystem? How are humans causing biodiversity loss? What is the greatest ca...
When a critical component or raw material becomes scarce, the entire supply chain can be disrupted, causing delays that ripple through to the end customer. Global supply chains are particularly vulnerable to scarcity. For example, the pandemic exposed the fragility of global supply chains. Lockdown...
