The greatest threats to coral reefs is the rising temperature of the oceans as a result of climate change and the acidification of the oceans due to increased levels of carbon dioxide in the atmosphere which dissolves in the ocean and forms carbonic acid.Aug 3, 2015
A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
Answer:
<h2> Each daughter molecule contains one parent strand and one newly synthesized strand</h2>
Explanation:
In DNA replication, each daughter molecule contains one parent strand and one newly synthesized strand because DNA replication is semi-conservative. One template strand is parental strand and the other one is its complementary which is new one, which is synthesized by DNA polymerase enzyme. So both daughter molecule contains one parent strand and one newly synthesized strand and they are same in the sequence of bases because each strand contains one original parental strand.
The illustration is missing the type of organisms known as decomposers. They break down dead animals and plants and have the vital role in returning the nutrients back into the system, where they can be used once more by the primary producers.
In the illustration:
The primary producers are the phytoplankton.
The primary consumers are the: krill, cod and zooplankton
The secondary consumers are the remaining species that feed on the primary consumers.
