Answer:  The blank in the question can be filled as-

If the type of food available changes, then over the passage of time, evolution of different beak types will result  that reflects adaptation according to the changing food habits because their body wants to adapt in order to survive and reproduce ( pass their genes to the next generation) under the changing conditions.

Therefore, the frequency of allele corresponding to beak will be enhanced or increased.

If the type of food available changes, then the types of bird's beaks will change with it, because their bodies are adapting to suit their environmental needs more efficiently.

Each fossil with the layer where it will be present based on are layer A-BIRDS, layer B -dinosaurs , layer C-amphibians, layer D-Corals ,layer E -trilobites.

<h3>What is the oldest fossil layer?</h3>

The Pilbara area of western Australia's Strelley Pool is home to the oldest known fossils. Stromatolites are fossilized mats of microorganisms wedged between sedimentary layers. The fossils have an age of 3.4 billion years.

<h3>How are the layers containing the fossils organized?</h3>

The Law of Superposition, which asserts that in undisturbed rock sequences, the bottom layers are earlier than the top ones, is the foundation for this theory. Because of this, certain fossil discoveries can be dated using the strata—a particular stratum of rock—in which they were discovered.

Which is a weakness of traditional food webs when they are applied to complex ecological problems?
Anna007 [38]

A food web does not represent all the links in an actual ecosystem.

Explanation:

A food web is also called food cycle. It is understood by the natural interconnection of chain and their graphical representation.  The concept is given by Charles Elton. He mentioned about the concept of food cycles in Animal Ecology but later this food cycle is replaced by food web.

Food web are limited representation of eco system. Ecologists can keep together all life forms broadly into one of the two categories which is called tropic levels.  These two categories are autotrophs and heterotrophs
