Zooplankton populations in Lake Erie and the Hudson River have declined by up to 70% since the arrival of zebra mussels because . Group of answer choices Zebra mussels feed on phytoplankton, which zooplankton need as a food source Zooplakton are reduced due to predator mediated competition Zebra mussels block sunlight penetration into lakes and thus prevent zooplankton from photosynthesizing Zebra mussels prey exclusively on zooplankton Zooplankton are replaced due to competitive exclusion

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
